Compost Tea Recipe – Inoculate Your Garden With Microbes
A compost tea recipe doesn’t have to be complicated in order to be effective.
In fact, the simplest compost tea recipes are often the best because they’re easier to experiment with.
In case you don’t know, compost tea doesn’t look like the picture here.
It’s actually made by putting a small amount of compost in a bucket of water and bubbling air through the water to detach the beneficial microorganisms from the compost as well as give them air to breathe.
We also add specific foods to feed and multiply those microbes. The resulting tea is applied to the garden.
To make a high-quality compost tea that’s going to provide benefits for your garden, you need to get a lot of factors right — air pressure, water quantity, size of the air bubbles, amount and types of compost and microbes foods, and on and on.
Today, I’m focusing on the ingredients.
Compost Tea Brewing
Whether you buy a compost tea brewer or make your own, you start with just a small amount of exceptionally good, aerobic, nice-smelling, fully finished organic compost.
(Here’s my post on composting at home. if you want to know more about that.)
A mixture of two or three different composts is even better. Using different composts will bring more microbial diversity, and you can even throw in a small amount of healthy soil.
You can put this compost first into a mesh bag or directly into a bucket of clean, room temperature water. Many people use a five-gallon bucket, which is fine if your pump is powerful enough.
If you’re just using a basic aquarium pump, I suggest putting only a gallon of water in the bucket and cutting the ingredients by 80%. Using less water ensures you have enough air moving through.
By “clean” water, I mean it can’t have chlorine in it. If you use city water, you need to let that bucket of water sit out for 24 hours for the chlorine to dissipate, or you can turn on your air pump for 20 minutes instead and that also does the trick.
If your city uses chloramine to disinfect the water, you need to add ascorbic acid (vitamin C) or humic acids to neutralize it.
Your air pump will blow air through tubes in the bucket. The air goes through the water and compost, keeping the environment aerobic to favor the aerobic microbes.
In the old method of making compost tea which was just to let it sit and perhaps occasionally stir it with a stick, those microbes would mostly stay attached to the compost and wouldn’t have enough air to multiply.
The new method gives them the right amount of air, plus we add the foods they need to multiply.
Compost Tea Recipe
Examples of good microbe foods include molasses, kelp, fish, humic acids and rock dust. Obviously, these products shouldn’t have preservatives in them, because preservatives are designed to kill microbes.
Here’s an organic compost tea recipe I’ve adapted and evolved for a five-gallon homemade compost tea brewer. This takes 1-3 days to make. We don’t really know when it’s done if we’re not testing it, but 2-3 days is a good time frame to start. The compost tea ingredients are:
- 2 cups good, aerobic, nice-smelling, fully finished organic compost
- 1 Tablespoon unsulfured blackstrap molasses
- 1 Tablespoon organic liquid kelp fertilizer
- 1 teaspoon organic liquid fish fertilizer
A good batch of compost tea can be a miracle worker when it comes to fulfilling your organic gardening goals. It’s a microbial inoculant to improve your soil food web, broad-spectrum organic fertilizer to foliar feed your plants, and even pest control (although it can’t legally be marketed for controlling pests).
And this simple compost tea recipe is all you need to get started. If you have any questions, feel free to let me know below.
Update: Nearly 2 years after writing this, I decided to start selling the same compost tea brewer that I use myself. You can check it out (and learn more about compost tea) here.
Hi Phil…great stuff, as usual. I’m looking for a solar powered aerator to drop in my compost tea bucket. Do you or anyone know if there’s one out there? I’d say such a device from the technospere might be allowable in the biosphere…so when the sun shines our little microbial buddies will get some oxygen. Rex Harrill from the Brix talk forum supplied a couple of your links. Very cool…and a great compliment to you.
Wow, that is a great compliment. Don’t know about a solar-powered aerator, but I’d recommend going for just a solar-powered generator that you can use for many different purposes, including the aerator. 🙂
I made my own. Took a 10W (12v nominal) solar panel ($20 on Amazon) and connected it to a very small submersible fish-tank pump (draws about 400mA) ($6.71 on Banggood.com). Connected a hose to the output of the pump and pointed it straight up, so it hits the inverted lid of my 10-gallon trash can, which contains the pump, water, and compost (in mesh bag). The water spray hits the lid, sprays/aerates and falls back to rest of the water, kind of like an aerating pond-fountain. My logic here is that it works for aeration ponds, it must work for this application. Plus there are no small holes (like in an aeration stone) to get clogged. Have had it running daily for about a month now, no problems.
Love the solar panel idea! And it sounds like you have the beginnings of an interesting system there. It won’t make good compost tea yet, though – it’s not pushing nearly enough air. Do you know the wattage of the pump? Even better, do you know how many cubic feet per minute of air it pushes?
Hi Phil, I read something recently about the use of compost tea during or just after the use of a subsoiler (ie yeoman’s plough or general sub soil ripper) where the soil is not turned over or up, rather just ripped in a line with a plough in the shape of an upside down ‘T’ like the keel of a yacht. I understand the great benefits of applying compost tea to biologically active areas of soil and vegetation however do you know of any benefits of applying bio active compost tea to soils such as inactive clay sub soils? I don’t see what the compost tea organisms can feed on in the inactive sub soil once they have consumed all of the molasses or other feed they were sprayed in with… The only way I see a benefit of placing compost tea into sub soil is if the farmer somehow mixes a substantial amount of organic material into the sub soil area to assist in creating/expanding the depth of topsoil. Some of these articles are written by influential permaculture teachers and it seems I’m not getting the point here! Your thoughts would be most appreciated.Kind regards,Ben.
Hi Ben, that’s a very astute observation. If there’s no organic matter down there, I would think that most of the microbes won’t stick around for long. Perhaps just being there for a little while will help improve the soil, though. Maybe applying some humates along with the tea would give them a better habitat. Perhaps some roots will find their way down in there to feed the microbes. I’d be very interested to see some research on all of this. And you’re right, applying organic matter would be the best if at all possible, and really, it wouldn’t need to be much to provide food and habitat for the microbes.
Thanks mate, yes I’m not convinced, however I am intrigued with the idea of regenerating otherwise poor soils. If anything I suppose keylining the soil could provide an area for sheet run off of water and topsoil to collect into rather than wash all the way down into a valley. That could be where the process may take off but it would need monitoring. Cheers, Ben
Hello Phil, Your compost tea advice, for a solid brew foundation, is, as usual, spot on. I wonder if I could get your opinion on a more advanced compost tea topic? I was watching Bob Webster, a trained biologist and organic gardening radio host, from OrganicTexas (on youtube). Near the end of his informative talk on compost tea he dropped a potentially very valuable tip. He says that adding corn meal can selectively enhance the presence of Trichoderma in our teas. He points out that it has evolved a set of enzymes to efficiently metabolize corn, hence its very widespread occurrence in the root-zone of growing corn. Trichoderma, of course, is an important part in many of those expensive bio-innoculants on the market. It has been show to promote growth and suppress pathogens in a huge variety of plants since the 1920’s. If Bob’s little side remark is correct, I think mixing up a batch of “tricho tea” might be very easy and potentially quite beneficial.Tell us what you make of this Obi Wan?Eric in Denver
That’s interesting Eric. I hadn’t heard that corn promotes Trichoderma. That could be useful, but in my opinion, the goal of most compost tea applications is to promote as wide a diversity of beneficial microbes as possible.If we focus on the Trichoderma, which certainly may be beneficial but may also inhibit certain microbes including mycorrhizal fungi, we’re not really doing much to improve the diversity of our soil food web.So in my view: Fun experiment for advanced compost tea brewers? Sure. Good goal for the other 99%? No, it’s probably better for most gardeners to stick to compost and perhaps effective microorganisms, and for more advanced gardeners to stick to balanced compost teas.
wow. somebody mentioned trichoderma fungus. Phil, this is the growing medium I’m currently trying. thank you, Eric for talking about it as I’ve found very little info or anybody recommending it. BTW, Phil, your tea is about what I’ve been using for a year, though I don’t have access to compost. Chris in Thailand
We have a worm farm that produces a lot of worm tea, which we dilute and feed the vegetables. Are there are disadvantages to this?
Hi Helen, I’ had a small worm bin for many years, but I just let the tea drain out of it, so I don’t have any experience with using it and I haven’t seen any research on it. It’s not near as diverse as compost tea, but I could see it being useful because it will have plenty of bacteria. I could also see it being detrimental – if it smells really bad, it may mostly be comprised of microbes that we don’t want in our gardens. Wish I could tell you more…
Hi Phil, I happened upon your site while researching the soil food web. What Helen is referring to is not tea but leachate. It can contain E. coli and other anaerobic nasties and I for one would never use it on my plants. Vermicompost tea is made the same way as compost tea–only it’s been proven to be more effective and have a greater variety of microbes. When I make vermicompost tea, I also throw in a little regular compost to get the best of both worlds. As I’m sure you are aware, there are also techniques to bias the mix toward bacterial, fungal or neutral. Keep up the good work.
Thanks Jim, yes, compost leachate is often horrible stuff, but coming out of a vermicomposting system, it can be beneficial. Helen, I should have mentioned that it would be best to get it tested by Soil FoodWeb if you’re planning to use it on a large scale.
Phil: I am very excited about this pump idea. I’ve been looking on u-tube and saw fellow from Alaska with marvel plants he wins ribbons on for size. He sells something like this, but my son has a little compressor he does not use much I asked him for it. It would be great on my 5 gal. drum a few days with ” STUFF” in it…like the items you have above. Thanks for this good article of advise. Also I want to grow salad all year here in Maine not far from you. I saw this done not far from here in grow trays in the windows….add this to your winter works and I’ll be watching. Thanks phil. Ruby at beach in Maine
Thanks Ruby. I definitely encourage you to play with the compressor. Making a really great tea with a homemade brewer requires lab testing (or your own microscope testing) and subsequent tweaking of the whole setup, but you can definitely make an okay tea with just some basic planning.
Compost tea results will vary. I’ve test exactly the same recipe that Phil mentions in his article above multiple times, but have seen no improvement over the placebo. I’ve also read a study from a university extension service that says you shouldn’t use compost tea on indoor seedlings –especially if it has molasses — because of increased damping off. According to the study, this is true even when watering from the bottom.That’s not to say it doesn’t work for some folks who hit the mark and get the right microbes growing in their tea. But my point of view is that brewing effective tea is more difficult than most garden writers suggest. It’s a garden investment that I would better make elsewhere.
Hi Bill, you’re definitely right about the fact that making good compost tea takes some effort. You certainly can’t put together your own brewer and expect to make a great tea without doing some lab testing and some tweaking to your brewer. Or if you’re already composting, it makes sense that using regular homemade compost tea may not improve your soil food web much more than your compost already has, and so won’t make much difference. That being said, I’ve been involved with compost tea since 2005, and the results often blow me away. You just need to get a good system going, as you said.
I take your point Phil, for the vast majority of applications we want to introduce as broad a spectrum of “good” microbes into the rhizosphere as we can, and let the plant-soil ecosystem select out what it needs, for example, via root exudates. In which case we should try to brew our tea with as wide a variety of quality compost sources (castings, pond muck, etc.) and as wide a range of quality food sources as practicable. (I would recommend the addition of inexpensive organic oat or wheat bran and soy bean meal.) This makes sound practical sense because the soil is probably THE most complex ecosystem on the planet, and we are only beginning to unravel its often subtle web of inter-connections. Until we know more we should proceed delicately in our gardens.All that having been said, I think seeking to selectively brew bacterialy or fungally dominated teas has proven an easy and effective technique (“Teaming with Microbes”). In some case, like for foilar spraying, brewing a less bio-diverse, more focused tea has real potential. I have little doubt that we will eventually be able to brew teas effective at targeting specific pathogens or pests. Or how about a “Tricho tea” inoculation for a new corn field?Now is our chance to get in on the ground floor of this exciting new science. Get a microscope (400x), learn to identify the main types of soil organisms, refine your brewing techniques, and set aside a place in your garden for experiments.It sounds much harder than it actually is, and there is plenty of work to be done.
Agreed, it’s an open field for people who enjoy experimenting. We just have to be careful not to get so specialized that we forget to adequately address the basics.
Great article Phil. I still do it old school in a 20 gal muck bucket without aeration. A couple shovels of compost, several handfuls of alfalfa pellets, and fill with water. Stir occasionally, and let steep for several days until the alfalfa forms a froth on the top. Dilute 5:1, and pour it on where needed without filtering out the large bits. Wonderful results. Feed the soil, not the plants. The plants will take care of themselves.
Thanks Bill. Yes, the older method doesn’t extract near as many microbes, but that doesn’t mean it’s ineffective. I suspect it’s acting as a nice little fertilizer. Easier to make, too.
Hi Phil – You know, that has been debated a lot on the SoilFoodWeb newsgroup. While aeration does produce better aerobic microbial numbers in the bucket, what happens after it soaks into the soil where the mechanical aeration no longer exists? The water near the surface remains aerobic sustaining the aerobic species in the tea, and the water that soaks deeper becomes anaerobic sustaining those species. In other words, the soil microbe stratification remains the same.I argue it is a self adjusting system. You can select for aerobic or anaerobic in the bucket by your tea making process, but that will all change once it hits the dirt.Further, merely watering the garden creates tea in situ. If you incorporate into the vegetable garden the same compost you brew with, you are making extra work for yourself. Tea allows you to spread the benefits of compost over a much larger area. You can add tea to a permanent potted plant that you cannot disturb to add compost to. Likewise, pouring tea on a lawn is less work than spreading compost. You can reserve compost for the beds that you want loamy soil while enhancing the microherd in the soil on the rest of your property.
I’ve followed the debates over the years. I mostly use compost tea to inoculate my plants and mulch, which is why I prefer aerobic. You’re right, there are applications for fermented teas, too. But compost is still better than compost tea if you have a choice. Compost supplies the organic matter that tea doesn’t supply, and has many times more nutrients. You can spray tea on your lawn and potted plants, which is a great way to get the microbes in there, but it doesn’t make up for a soil that’s low in organic matter. So the “extra work” of compost is quite critical extra work.
Thanks Phil. I have used this recipe before and I have been pleased with the results but it has been a while. I think I need to try it again. Question: When making the tea it starts to develop a bubbly foam on top. It almost looks like a pond scum. I thought I read somewhere that that is a good thing. Is that true? Also, I have some mycorrhizal fungi in powder form. If I added a little of that into the compost tea would it multiply and/or be beneficial? Thanks as always.
Hi Andy, the foam is normal. It’s no problem. Adding mycorrhizal fungi to the tea isn’t beneficial, and they don’t multiply. If you’re planning to do a soil drench, you can add them to the tea right before you spray.
Wow! this is indeed a very interesting tea. Thank you so much for sharing this page.
Great article. You mentioned, “Examples of good microbe foods include molasses, kelp, fish, humic acids and rock dust.” You include kelp and fish in the recipe but not humic acid or rock dust. Do the kelp and fish replace the humic acids and rock dust? Would it be a better tea with them? If so how much humic acids or rock dust would you add to a 5 gallon bucket of tea?
There’s still a bit of debate about using humic acids, but I use it especially if I’m brewing with city water, because the humic acids tie up the chloramine that my city uses. I use no more than 1 Tbsp. I also use 1 Tbsp of rock dust.
Timing is everything they say…..last winter here in Michigan was quite mild and there’s no saying what sort of winter this one coming will be but my question as I am starting to put my heap to bed for the winter is this….. will the areas of my garden in which I intend to plant and other areas with berries and such benefit with a good drenching of compost tea NOW…or should I just wait until early spring when the garden’s soil is nice and warm. I turn my heap in January and the column of steam that rises into the air is quite impressive. Thanks for this great blog!
It will definitely benefit now, and it’s worthwhile if you’re planning to grow and harvest crops this fall.If you only make tea a couple of times a year, it’s nice to do them when you’re actively growing crops – spring, summer and perhaps early fall.
Phil Found your “Brewing Compost Tea – Some Important Tips For Success” video very interesting. Tried finding the air pump/blower you used, but no luck. Could you please share the manufacturer and model number and or where you purchased it. Thanks much, Ron
Hi Ron, it’s the 5 gallon brewer: https://www.smilinggardener.com/sale/compost-tea-brewer/
Find an aquarium store of the aquarium place in your grocery store……they got em
Hi Phil, with the compost tea recipe above, from a 5 gallon container of water you mentioned to go one gallon of water, but how much ingredients would I need to use with one gallon (because I have a small aerator not an industrial one.By cutting the ingredients by 80%, I am not sure how to do this, can you pls help.
It would be:
-1-2 cups good, aerobic, nice-smelling, fully finished organic compost
-1 teaspoon unsulfured blackstrap molasses
-1 teaspoon organic liquid kelp fertilizer
-1/2 teaspoon organic liquid fish fertilizer
Hi can I use a good organic compost bought from Bunnings? because I have not got my own made yet? and how do you apply it, do you mix this tea with unchlorinated water before i give it to the plants, if I have to add water how much do I add to that one gallon (4 Litres), and is it sprayed over the leaves or do I give a small amount into the ground where the main stalk of the plant is?
Odds are that the compost from Bunnings is not necessarily loaded with beneficial microbes. You could use a little of it, but I would recommend also getting another source. If someone in your city is making fresh worm compost, that is usually a good addition to a tea. You don’t need to mix it with any more water – just spray it directly onto plant leaves and also it’s great if a little goes on the ground.
Phil the tea brew do you mix this with additional water, how much water to a gallon of tea brew. Also do you feed to where the stem is in the ground, or spray over the plants leaves?
I don’t mix with more water. I try to spray the whole plant – leaves, stem and the soil beneath it.
I’m thinking of trying something a little different to brew my tea. I have a small aquaponics system I’m going to use. First I’ll remove the fish. I will be able to brew 100 gallons of tea ! Tell me what you, everybody think/s.
Worthwhile if you have 20 acres, but otherwise there’s no need to make that much tea. 5 gallons of good tea can cover an acre, and it’s certainly easier to brew less.
I have a response to locating a solar aerator. I found one at http://www.1000fountains.com that will aerate 48 gals. per hour for $49.00. Hopes this information helps. I do have a question about how much aeration Is required for a 50 gal. container in order to create sufficient oxygen for healthy and successful tea making? Is their a simple formula maybe? I’ve been looking all over for this information. Everything I find is very vague. Thank you
Hi PhilI have a couple of of questions. Is it even worth doing with an aquarium pump say a gallon amount as you suggest? Can I use sea water in my compost tea? I live on the coast so it is easy to get. Also what is the best way to apply the tea with a spray?
Yes, it’s worth doing. You may not make an incredible tea with that small of a pump, but it can be decent. You can use perhaps 1 Tablespoon of sea water per gallon of water. I talk about how to apply it about halfway down this page under the subheading ‘How To Use Compost Tea’: https://www.smilinggardener.com/sale/compost-tea-brewer/
Hi Phil. Ive been debating whether to get a batch of compost tea going, but am starting to feel a bit discouraged by some of the comments on this thread. I dont have access to a lab, nor the money for testing. I have a pretty decent green thumb, and have never had any problems with growing anything before, even in the absence of compost. If I were to build a tea brewer, what would be the most important aspect of the build? Is too much aeration a bad thing? Is it possible to over fertilize with compost tea? If I were to built one, it would be with a larger garbage can and a sufficient commercial aquarium pump. Any input would be great!!
Too much aeration is bad, but much more common is too little. It’s not possible to overuse the tea. Tim Wilson’s website gives some great tips on making a brewer: http://www.microbeorganics.com/
Hi Phil,
Just started my Compost Tea Brewer for the first time. The pamphlet in the brewer says to run a batch for 12 hours, kiss says 24 to 36 hours. Does it matter?
Can you put Humic Acid in the brew?
My wife has a friend that would like some “tea” for their garden. Can I let a partial brew run for 72 hours to keep it aerated?
Do you put EM in with the brew? If so, can you send me a link to the instructions.
I’ve had difficulty finding all the material I’m looking for and have been on smilinggardener.com a lot this evening. I’m looking for charts of what to mix with what and what product to use on what, etc. [I’ve bought one or two of everything you sell, I think] 😊
We bought the glacial and basalt rock dust. Which one should be used in the brew?
Doug
Their original brewer could do a brew in 12 hours, but the pumps didn’t last long. These newer pumps take longer (24 hours is great, 36 hours is usually even better), but these pumps last a long, long time.
Yes, you can use humic acid. Ideal is to put 1 Tbsp of humic acid in at the beginning and run the pump with just that for a couple of minutes. If your water has chlorine or chloramine, the humic acid will help neutralize it.
72 hours is pushing it, but it should still be okay. It won’t go bad as long as it stays well-aerated, but the microbial mix of the tea will change to the point where it won’t be as effective as a 36-hour tea. I’d have no problem doing this occasionally, but would want it to be shorter for most applications.
Yes, I put 1 Tbsp of EM in along with the other ingredients at the beginning.
You can use all of my products on all types of plants. As for what to mix with what, the calculator can be helpful for that: https://www.smilinggardener.com/sale/calculator/
You can use either or both dusts in the brew.
On your compost video you use a garden hose with a sprayer; however, in another place you say do not dilute the brew…..which is it?
Undiluted is best for foliar applications of compost tea, in order to get the max number of microbes on the leaves. Diluted is still okay, but undiluted is ideal. For soil applications, diluted is fine.
Hi Phil,
Most of my plans are for foliar spraying. Since 36 hours is better for a brew, what do you do if rain shows up 1.5 days after beginning your brew?
How far in advance of a rain should you apply compost tea as a foliar spray?
I’m happy to brew for anywhere between 24 and 48 hours, so if rain is coming, I have some flexibility as to when I stop it. As far as applying before a rain, I’ve never seen any set rules as to timing. A light rain is fine. A heavy rain will remove some of the organisms, but not all of them.
Phil,
Are you continuing to use molasses in your teas? I see that Elaine Ingram is no longer using it in her recipes. Thanks for helping me learn more about gardening.
Yes, I still use molasses at the above rate. Just that small amount. And I make sure my tea is well-aerated during brewing.
Hi sir Phil, you recommend unsulfured blackstrap molasses but most cases here in our country we used ordinary molasses for brewing (non food grade or used for commercial feeds only). Does it matter? thanks
Food grade isn’t necessary but sulfured molasses is a problem because sulfur kills microbes.
Hi Phil!
This is was amazing! Thank you!
I made the tea as per your recipe but left out the kelp bc I don’t have any. I hope that’s ok. Sort of in the vain of another commentator here by the name of Bill_G, I was wondering what happens when we store the tea. DOesn’t it become anaerobic in the jar? If so, doesn’t that change the nature of the tea and its beneficial makeup? Could I still use that tea in my garden? And what happens when these microorganisms hit the soil? if I use the fresh tea, once those nice aerobic microorganisms get into the soil, will the be ok with their new (less aerated) environment?
It’s best to use the tea within a few hours because, you’re right, it starts to go anaerobic if just left in the jar. As for what happens when they hit the soil, the top few inches of the soil have enough air for them, and that’s where most of them will be. It’s good to spray them on the leaves, too.
Hi again,
I have another question, could I make a tea with veggie scraps and an airstone?
Thank you!
Yes, but it won’t be nearly as useful. Good compost has millions of times more beneficial microorganisms and many more nutrients, too. And an airstone may be helpful but the big thing is that the pump needs to be powerful enough.
Here’s a question about shortcuts from an amateur. I am a home gardener, and have been inspired by reading The Omnivore’s Dilemma and learning about permaculture. I’m wondering if there are any substitutes for the kelp or fish meal. Could I use a cup or two of water from a well established pond that has carp in it? Can I throw in scraps from cooked or uncooked fish? Also, if I just make “tea” from mixing only compost or very rich soil in water and pour it over my lawn, am I giving the grass some of the benefits / nutrients of the compost without “brewing”? What advice do you have for people who are not bent on perfection of the recipe?
-Could I use a cup or two of water from a well established pond that has carp in it? Yes, but ocean fish/seaweed/water is much more nutritious.
-Can I throw in scraps from cooked or uncooked fish? Definitely.
-Also, if I just make “tea” from mixing only compost or very rich soil in water and pour it over my lawn, am I giving the grass some of the benefits / nutrients of the compost without “brewing”? Not much. It’s a tiny fraction of the benefit.
-What advice do you have for people who are not bent on perfection of the recipe? Use effective microorganisms instead.
Great conversations! I’ve been brewing compost tea in a 30- gallon barrel for 15 years. One of your comments (April 13, 2017) indicated that too much aeration is bad. I had not heard this before. My pump really churns the water, which I thought was a good thing – a little aeration is good, lots of aeration is even better. Can you elaborate and advise please?
My recipe is compost, earthworm castings, kelp meal, glacier dust, molasses, water.
I have seen it mentioned, but not sure what the issue would be. I don’t think you have to worry at all.
I read, (I’m pretty sure on Tim Wilson’s site) that too much aeration can “shred” the microbes. Obviously, the larger the batch the larger the pump needed but I don’t have specifics. On his site he does have information on building a 5 and a 50 gallon brewer and pump sizes recommended.
BTW, I’ve really been enjoying your site.
Thanks!
That makes sense. I suppose too much aeration is kind of like a rototiller when you think about it.
Hello Phil
It might help some of your followers for me to post my attempts at fertilizing our organic crops(ie. soybeans) with homemade compost teas by foliar spraying. It’s a learning experience for us and could be for others too.
Let me know, if you want me to start posting our efforts and results.
