mr bond, i guess i came across a little harsh. I did not intend to point fingers. I have read this complete thread twice, but with nearly 1500 posts, i must have overlooked some critical details or did not think some details were as important as others.
The is no light coming in the buckets (maybe through the hydroton in the netcups, but that is taken care of now), they are completely wrapped in reflexive material. I have a chiller and had one all along. I think the downfall was a combo of the extra sweet in the tea, not enough air, and extra additives in the res. I am currently doing a physan sterilization and brewing a fresh, clean batch of tea. I do realize that it was the brewer's fault, so i will fix everything i can and try again.
How high up the net cup should that water level be? I completely missed this. post 855
"Water should be splashing on the net pots to keep them moist, but the water level should be an inch or so below the pot to promote air intake and to prevent standing water that could collect in the pots and go anaerobic. "

"The concern for disease is a secondary reason to leave the water level below the pot. If you have true net pots and they drain or the water flows freely through them, you probably wont end up with pockets of anaerobic water which can lead to root rot. The real reason to leave the gap is for air intake of the roots. They should remain moist but be free to take in oxygen, as the water can never supply enough oxygen no matter your DO levels."
so the bennies live in the hydroton, and just get splashed down towards the roots? With 6" net pots, should i worry about keep the top few inches of hydroton moist?
