alright i gotta get this cleared up once in for all cause this sway of information is killin me. I bubble my teas from the moment i mix up all the ingredients. Iv been using peruvian guano consisting of 10-10-2, as well as liquid kelp, molassas(concentrated stuff called heavy weight), SPT, worm castings, and the occasional dolimite lime, while always using tap water thats sat no less then 48 hours so its clorine free-also checked with the water department to make sure there's no chloramine.
Every time i brew this batch with the 10-10-2, it always turns to an unpleasant smell rather quickly, and after brewed for a couple days i have to keep "knocking" the bubbles back down that it creates in the bucket(while always bubbling), but when i would brew with a Nitrogen guano it wouldn't succumb to a foul smelling brew.
iv been using the 10-10-2 because iv been on the verge of flowering, was waiting on an a/c window unit. and will continue to use the 10-10-2 going into the flowering until the 3rd week when ill start to cut back on the Nitrogen.
But my quetion is, why would my natual tea start to go sour on me? i have given no reason to start to become anerobic. to hit any possible angles on this problem, i use the same air stone each time but soak it, clean it, and then hook it up to the pump to get any water out.
Ohso you said that the anerobic start to increase because of the lack of disolved oxygen but its always bubbling. The only factor that i can see is the increased number in nutes- 10-10-2, reacting with the SPT to produce alot of bioconversion with the SPT going to town with all the nutes. So im not sure whats the deal, but its really my only problem with my grow, and its kind of a big one so could you help me out and try to address it, thanks man

Swishatwista.... What "Grow Space" was talking about was making fertilizer tea without using a source of constant oxygen like an aquarium air pump. I told him, pouring his tea from bucket to bucket, several times a day would add oxygen and help keep his tea aerobic. This will work for several days, but after that, the anerobic bacteria will start to gain ground. Because as the micro-beasties increase in population, they will begin to exhaust (use up) the oxygen at a faster and faster rate. In his situation, not having an air pump, will allow this to happen faster.
.
If you constantly bubble a tea, it will stay aerobic (sweet). The longer you bubble (brew) it, the more it is broken down by the micro-beasties. If you use it in the first few days, say 24 hours to 72 hours of bubbling, I have always seen the best results.
.
I once bubbled a tea for an entire month and used it on just a few plants. They did not show any improvements over the other plants feed teas, bubbled only a few days.
.
I later learned, what had happened was I allowed so many micro-beasties to reproduce that they actually consumed a large portion of the NPK in the mix. Did it get lost ? No, just converted. Later the dead bodies of the micro-beasties will either breakdown (freeing up the NPK from their bodies) or they will act as a food source for other micro-beasties (& get bioconverted - eaten & pooped out in a smaller / more soluble size). So, you don't really lose NPK, it just gets converted from one form to another.
.
Bubbling for long periods of time, say more than three days, tips the scales and causes more micro-beasties to be present in your tea.
Bubbling for 24 to 72 hours provides the best compromise / balance of NPK value & micro-beastie population.

That being said, don't get hung up on smells. What smells fresh & earthy to one person, does not smell the same to another person. Especially with bat guanos, their odors do vary, based on what they ate in their diets, the age of the guano, how it was stored, moisture content...etc....

Hope this helps.....
