After initially answering the question about what type of water is best for aerated tea I found myself going into greater detail than what your question asked. So, I decided to simply go ahead and describe the entire process just in case there are some people who are interested in a more indepth explanation. First, the best water is pond water, where there are fish living in it is the best. Ponds with fish have all kinds of material that microbes really like. There will be a significant increase in the quality of your tea if you can use pond water. However, you can make great tea using tap water where the chlorine or chloramine has been eliminated. Be sure to check with your local water district to determine if your water is treated with chlorine or chloramine. If your water is treated with chlorine all you have to do is put the airstones in your bucket of water and turn it on for about half an hour, and that will take care of the chlorine. Chloramine, on the other hand, is a totally different situation. Chloramine is far more toxic and it will not outgas like chlorine. You have to go to a pet store and buy the drops that are used in aquariums that break the chloramine bond. Be sure to use twice as much as the directions say to use. The stuff is very inexpensive so don't worry about the cost. I think I use 4ml for 5 gal of water. For some reason I thought my city used chlorine and so I was aerating the water before using it. I made two batches of tea for myself and one for a neighbor before I called the city to verify the situation. When the water guy said chloramine I said, to myself, CRAP. I just wasted three batches. And since I use worm castings it was an expensive lesson. I don't know why I assumed the city used chlorine. But it was really dumb not to call first. Also, do not use pantyhose or a pillow case if you put your compost in a bag. The openings are too small to allow fungi to pass through. Fungi are simply too big. And when you consider the fact that there will be a certain amount of sediment that will build up inside your bag the holes are made even smaller to the point that even bacteria might have difficulty passing through. Use a paint strainer bag. And be sure to put an airstone inside the bag holding the compost as well. The bubbles inside the bag really help the bacteria to release from the organic material and push it into the water where they can really begin to multiply. I use a 70gph aquarium pumt that has two hose plugs. I have found that this allows me to attach the hoses to a three hose gangline. A gangline is much better than using a manafold to split one of the lines for two airstones. What I found is that air takes the avenue of least resistnence which means that if one of the airstones is not as poorous as the other then little air will be pushed through that stone. However, if you have a separate air hose for each airstone then air seems to be more evenly distributed resulting in all the airstones being very usefull. Many people do not use a bag to hold the compost. They simply put compost in the bucket, then fill the bucket with water and begin to aerate the tea that way. The problem with this method is that 99% of the compost settles at the bottom of the bucket which prevents effecient oxygenizatin (I think that is how you spell that). Unless you intend to stand there and stir the sediment for 32 hours, use a bag. After putting an airstone in the bag, tie it closed with a piece of twine and then tie the other end to a wood dowel or some other thing that will keep the bag suspended off the bottom of the bucket. With a bag, all I have to do is squeeze the bag every couple of hours just to make sure the bacteria in the compost is getting well aerated. I fill my bag with about 5 cups of worm castings. You can use any good quality compost, just be sure the mateial is FULLY composted. When you place the bag of compost into the water add 1oz of unsulphered molasses. This is the energy source the microbes will need to sruvive. Take a stick or a long spoon and stir the water so the molasses does not simply make a blob at the bottom of the bucket. Turn on the air pump and walk away. At no time should the water stink. It should smell earthy, or even slightly sweet. This is an indication that you are making a good aerobic tea. If for some reason your tea has an amonia smell, or it stinks at all I would suggest tossing it out and starting over. If for some reason the power is interrupted for a couple of hours, I would toss the whole thing out and start over. If you get a lot of foam on the top, use a couple of drops of vegetable oil. DO NOT use olive oil. Olive oil,like honey, has antimicrobial properties which will kill your tea. Also, do not use honey in place of molasses. After about 8 to 10 hours take the bag of compost out of the water and put the airstone that was in the bag into the bucket with the other two airstones. You can either put this compost in the garden or back into the compost bin. After taking the bag out of the bucket let the tea brew for between 24 to 32 hours. The tea will hit its max benefit, for a 5 gal bucket, at about this time. If you are going to brew the tea for longer than this you will need to add a tablespoon or so of molasses. Remember bacteria reproduce very fast, like every five minutes. During this process the number of bacteria will be increasing exponentially. All these bacteria need something to eat or they will die. One comment about the amount of air. Some people have gone to extremes and push so much air through their bucket that the water looks like the water you see in a juccuzzi. This is way too much force. Fungi are actually very large structures and you will totally destroy them if you push the air throught the water with too much force. A 70 gph aquarium pumt I bought for $15 at Petco is all you need for a 5 gal bucket. If you are going to use a 55 gal barrel then you would need to increse the size of the motor on the pump, but not for a 5 gal bucket of tea. The water should look like ther is a gentle rolling boil. Not like it is splashing out of the bucket. If you want to add fish emulsion or seaweed, add these at the end, a few minutes before you take out the airstones. Fish hydorolisate is really good stuff that fungi really like. Seaweed is another excellent product. If your tomato plants have problems with spider mites use seaweed every day until they are gone. Seaweed is fabulous for treating spider mites. If you intend to watering the garden with the tea try and apply it to soil that is moist; water penetrates moist soil much faster than it does dry soil. This will help the microbes penetrate into the soil faster which will result in less UV destruction. This also applies if you are doing a foliar application. The less UV the better. That means before 8:30 or so and after 5pm. It is the same idea why we should not till our garden. Tilling exposes the microbial matter, bacteria and fungi, to the sun where they oxydize and die, but that is a whole other discussion. Finally, be sure to apply your tea within two to three ours (no more than four hours) from the time you take the airstones out. Immediately if you can. Do not let it sit around for longer. Application: I just use a 2gal bucket that has a nozzle. I use the nozzel when I intend to foliar feed and I take it off when I simply want to ground water the plants. When you intend to foliar feed it is always best to try to get the tea on the bottom of the leaves too and a pump up sprayer works great. If you use a sprayer do not use a really fine mist. Be sure to use the setting that gives you the biggest dropletts. There are two primary reasons for this. First, you want the tea to stay on the leaves as long as possible. If you spray a really fine mist there will be a significant amount of evaporation before the plant has time to take in the tea. If you apply the tea using the largest dropletts you will greatly increast the time the tea stays on the leaves which will allow more time for the plant to take in the tea. Second, as I stated earlier, fungi are much larger than bacteria. If you try to use a setting that produces too fine a mist you will simply turn the fungi into mush, killing the fungi. Using large dropletts allows the fungi to be applies without killing them. This is a good thing. Clean your bucket, hoses, and aristones after each batch with clean water and a little hydrogen paroxyde. Do not use Clorox bleach. Clorox has added an ingredient that is designed to keep the bleach on stuff longer. This addative makes it difficult to fully remove the bleach film. Obviously, bleach is not something you want in your bucket or on your airstones the next time you go to make a batch of tea. I know I went way beyond just what kind of water is best, but I figured there might be people who are interested in the whole process. Sorry if I turned a simple question into a novel. The short version: one 5 gal bucket - lid is optional. unchlorinated water an aquarium pump (minimum 60gph) and three aristones. My airpump came with hoses. a three-line gangline paint filter bags (package of two cost .95 at DoIt Center) unsulphered molasses. I bought 1gal at Smart and Final for $16. a little twine Extras: fish emulsion or fish hydrolisate, seaweed. Total cost, not including fish emulsion or seaweed = $48.00. Bucket, pump, airstones, gangline, paint filter bags and chloramine drops.If my city used chlorine I could drop $12 off the price tag. If I used a splitter in stead of a gangline I could drop anothe $9. Tom

Here are the instructions. This still does not answer my question about using compost tea as the "liquid medium" for spraying the nematodes...nor does it address whether it's ok to add the nematodes to the water BEFORE beginning the brewing process. APPLICATION RECOMMENDATIONS: Application for the 10 Million nematodes: Mix with water and spray or sprinkle on the soil along garden, lawn or crop rows or around larger plants. Place the entire sponge of nematodes in a bucket. Pour at least two quarts of water over the sponge and repeatedly squeeze for a few minutes to get the nematodes out of the sponge and into the bucket of water. Discard the sponge and pour the water into a sprayer or water can. At this stage, you should have the amount of nematodes indicated on the bag suspended in about two quarts of water. Add clean water to dilute the suspension and make up the volume that your sprayer requires. You can always add more water for distribution of the nematodes to cover the required square footage. Just add 2, 5, or 10 gallons of water so that you have enough to allow even spread of the nematodes. Keep the soil moist during the first 10 days after application.

Old socks, old kitchen tea towels, old t-shirts, old sheets/pillowcases, coffee filters make good small bags, old cotton shirts, etc. Cheese cloth is great and sold in the paint department. ;) Thin fabrics work better than thicker ones - anything that you can form into a bag shape. Dave

In the container forum, there is a thread I started that has been ongoing a few days regarding Mycorrhizal Fungi and specifically their effect on container grown plants during hot weather. A condensed version of what we've talked about there: Some ectomycorrhizal fungi that colonize the roots of trees can be found growing in a compost heap, but soil and leaf mold from a forrest floor are better sources of free spores for MF. The endomycorrhizal arbuscular fungi that colonize the roots of grasses and vegatables don't grow except on the roots of plants and will not reproduce in a compost heap. Starting from a sample of soil from very healthy grass roots or a commercial inoculant is the best source to grow them from. The only way to grow them is on the roots of living plants. For small amounts of inoculant for containers or to start growing your own, the cheapest source is Myco-Grow Soluble from Fungi Perfecti. This product is about $8 with shipping for an ounce that will inoculate up to 200 plants when dissolved in water. Many others are available, but this was the best one we could find that had lots of strains of MF and sold it in small quantities for individuals rather than commercial growers. When mixing an inoculant with water to pour on the soil, it is probably best to use filter water, rain water, distilled water, or Chloramine neutralizer in tap water. While the chlorine and chloramine in tap water are neutralized by soil when you water plants and doesn't do much damage to soil microbes below the top inch of soil, dumping the inoculant spores directly into chlorinated tap water may kill many of the spores you've just paid for or collected. Here are two artilces about growing your own MF inoculant http://www.extension.org/article/18627 http://newfarm.rodaleinstitute.org/depts/NFfield_trials/0404/mf_update.shtml Here are two articles from Texas A&M research on containers and MF during hot weather http://aggie-horticulture.tamu.edu/faculty/davies/research/abstracts/pdfs/2005-130-jashs.pdf http://www.hriresearch.org/docs/publications/JEH/JEH_2000/JEH_2000_18_4/JEH%2018-4-247-251.pdf Below is the link to the thread in the Container forum Here is a link that might be useful: Mycorrhizal fungi helps plants survive high temps in containers
