Hey guys, before we start in on the "use the search" and all that jazz I have been. I'm in dire need of some advice and would really appreciate if someone could point me in the right direction.

I'm just starting to flower in a BCNL bloombox and I noticed some root rot on my plants yesterday during a transfer and res change. I have been using 5ml/gal h202, and I placed the plants in a clean res w. nothing but pH balanced water and h202. I also made a 5ml/gal h202 spray and gave the roots a spray down before returning to a clean res w. week 1 flowering nutrients.

Here is my concern: I HAVE BEEN USING 3% HYOX!!! I know I messed this up relatively badly, as I should be using 35%(???). I just added about 250mL to my 23L res. So is using 10-11x more 3% hyox going to be effective? I can go to a hydro store and grab some 35% I'm just very concerned about my plants that WERE incredibly healthy until my res temp was off.

Good luck i have some Mild Root Rot and im thinking of soaking in h202 water or in Hygrozime Water

Thx smokedup, +rep; I'm not familiar w. guardian angel. I solved the root rot by transferring to an h202 and clean water bath, cleaned my res with bleach solution and mixed a fresh one up. This curbed it nicely, I've been using frozen water bottles to keep my res temps down, but it's becoming a little bit of a pain in my ass.. I just don't understand how anyone is able to keep their res cool in these boxes; the internal temperature is around 78 with my ambient room temp at 66! I got some 29% h202 and am using 5ml/gal, but I think I'm getting some root rot starting again due to constantly fluctuating res temps.. Any ideas for something to be added to my res weekly as a preventative rather than curative measure? I'm a little sketched by adding bleach, although I can imagine that killing the pythium.

I run a drip system on my mothers and it only turns on for half an hour every two or three days depending on the humidity. Is it possible to time your drip periods so your pots can get a chance to dry some. In my mother room the fans kick in at 80 degrees and cut out at 78. The electric heater system is set at 75 degrees. Just wondering.

My drip emitters run 5 minutes twice daily; enough to make sure there is no salt buildup, but not so much as to water-log the root ball. I would decrease watering but they're in prime flowering time, and any less watering would probably be detrimental. I keep my mother in coir and only water her every 4 days or so when she gets dry. I really think my main issue is high temps more so than damp roots. The system has a pretty effective outtake fan on the flowering side, as well as both intake and outtake fans for the HPS lamp. Overall it is cooled really nicely, it just invariably runs quite a bit hotter 28" under a 400w HPS with dual t5 lamps below. The reservoir is all white as to reflect as much light as possible. Just when the inside of the box is at 78, eventually the reservoir heats up to around 70.. I'm going to do some more forum research on this, and maybe invest in an aquarium chiller eventually...

Sealed some light leaks in my res, increased h202 and grabbed some hygrozyme yesterday. Hopefully this will do the trick
