Man I hate to make you type more than you did, but what was the exact recipe for the tea...there are several versions...how many gallons of tea did you make?...was it distilled or tap water. if tap does it have chlorine /chloramine(sp)? did you use unsulfred molases? how many hours did you brew the batch? what is your water res temp?. about how cold or warm was the water you used to brew the tea with?.....about your grow, why 5.3 ph?...that seems way low to me, unless that is what is called for on the nute bottle..........as you can see, any question about tea or slime, is not just a cut and dry simple answer.....but if you were a patient and were gonna die...and i HAD to make a guess...Id say that you added to much molasses to your tea or else didnt brew the tea long enough for the microbes to eat up the molasses....or went bat shit crazy and added molasses directly to your res. .....however you didnt say you had slime, you said you are trying to PREVENT pythium.... the foaming we usually see is a result of bad bacteria (slime) being gobbled up by good bacteria, or bad bacteria being fed by organic matter or (in your case) the molasses.... so the bigger question that I would have is, if you dont even have slime OR pythium....what the hell is wrong with your water that it foams when tea (undercooked or not) is added.?...
Alright, I followed the instructions given by Heisenberg at the very very beginning of this thread... here it is:
-------------------------------------------------------------------------------------------------------------
Start with non-chlorinated water. I make 2 gallons at a time, but you can easily adjust the additives for whatever amount you wish to make. Now put the water into a bucket and throw in a couple air stones. The more air the better. You want the water to be
almost turbulent from the bubbles. Now, add 15-30ml of aquashield and about 1/4-1/2 scoop of the ZHO powder. You will be breeding these into the billions so it doesn't really matter how much you start with, just don't overdo it. Now take an old sock or pantyhose and fill it with about 2 handfuls of EWC or Ancient Forest. Tie off the sock and place it in the water above an air stone, or better yet, feed an air stone down into the sock itself. If you want, you can just throw the EWC directly into the water and strain it out later with cheesecloth or even an aquarium net. Next, add about a tablespoon of molasses to wake up the microbes and give them something to eat. We will only be feeding the microbes in this tea; never add food for the microbes to the res itself. It's okay if the bennies in the res starve. You will be replacing them every few days. Now let the tea bubble at room tempeture for 48 hours. It can be used after 24, but will be more active and diverse at 48. If you use EWC you will probably notice a foam eventually, this is normal. After 48 hours you can store the tea in the fridge where it will stay fresh for about 10 days. Once it starts to go bad it will develop an odor. If you ever detect an odor from your tea, throw it out and make a new batch. Fresh tea can have a range of smells from earthy to mossy to shroomy. Bad tea smells like gym socks, fecal matter, or decay.
Initially, add about 1 cup to your res for every gallon of water, and then add 1 cup total every 3 days after. If you can, pour a little over the base of the stalk to inoculate the root crown. Your water might get a little cloudy but your roots will stay white and stimulated. When you use tea and practice proper res maintenance you can feel confident your roots will be healthy. By multiplying the microbes this way your products should last a great deal longer. Once you have eradicated slime and simply want protection from future outbreaks, adjust the tea dosage to 1 cup per 10 gallons about once per week..

This is the recipe i used.To start, i got 2 gallons of tap water, boiled it to get rid of the chlorine. After it boiled for about 20 minutes, i put it in the bucket, added slightly less than what is called for in the above recipe, about 1/4 of a scoop of ZHO powder, roughly 15 ml of hydroguard, and 2 handfuls of EWC in a sock added to the mix over the bubble bars. Next i added about 3/4 of a tablespoon of unsulphured molasses and let it bubble for 48 hours. Like mentioned in the recipe, there was a foam on the top of the tea, which i though to be okay.. The tea was brewed at around 77 or 78 F and there was a little over 1 gallon produced after boiling the water and allowing the mixture to bubble for 48 hours.
There is one thing wrong with my system that i think is questionable.. Using a MH light, my res temperature has been a little higher than i would like, when i checked it about 20 minutes ago, the res temp was about 83 F with a PH of 5.5 which is about where I want it as opposed to the original 5.3 i listed before, correct me if i'm wrong, i've been told the optimal PH range for cannabis was between 5.2 and 5.9.
Seeing this high res temperature, I just now decided to raise my light a little higher over the plants (it is now about 2' over the plants and i figure this is okay since the intensity from a MH light is so high). Also, note that I have had the light on 24 hours a day for the passed few days.. Finding this high res temperature, I am going to go back to my 18/6 light schedule. Hopefully this well help the high res temperatures.
Dynagro foliage pro is not organic.
As for what the hell is wrong with my res and the reason for the foam on the top, This is what I
THINK after reading your response: I think that my res is running a little bit warm and pythium is beginning to show up in the res, however, since I am running bennies, the pythium is being consumed, hence the foam.
This is strictly speculation, and i could be totally wrong.
Also, is there a cheap solution to chill a 10 gallon res? many of the options i see online are hundreds of dollars
