Thanks for the info guys. Room temp is running around 75 to 78, but that's away from the lights, top of buckets are running around 80 to 84 on one and the other runs around 90. Two different types of reflectors are being used, one is a bat wing and that's the one that runs higher temps at the bucket. Fan is running across both to help dissipate the heat, but the two plants are still small and hasn't created a canopy yet. Thought about painting the buckets white as well as using some kind of insulation, maybe foam, to help block out light and heat. Water temps do play a huge role in the formation of bacteria and mold. Ever hear of FATTOM? It's the recipe for breeding bacteria on food, Food, Acid, Time, Temprature, Oxygen, Moisture, and a bubble bucket produces pretty much all of these. Acid levels arent too low or high, Plenty of time, temps are always in the danger zone of 40-140 which is the breeding temps for bacteria, plenty of oxygen is present in the water due to air pumps, and moisture is abundant, the food can be the nutrients especially organics as well as any sugars that may be present for bacteria to munch on.
After the last disaster the buckets, lids, air stone, hydroton, tubing, PH pen, TDS meter and caps,eaduring devices, and the 5 ml droppers was soaked over night in a strong bleach solution, and the floors and walls were washed with a strong bleach solution.
