Deja if you're pretty sure lack of 02 is the answer then good. If you can get the root stuff I would....my hydro guy swears its the best bar none.

Never heard about the penny theory so can't recommend it myself and would worry about possible copper toxicity.

Cannazym is the best to prevent root rot....all conditions given being the same and Root Exeluater (however the heck it's spelled) is best to TREAT root rot.

Stay on top with the H202.....it'll be the only thing killing the pathogens.

What number ppm were you/are you at?
Weedhound Reviewed by Weedhound on . Root Rot Strikes Again So I started 5 plants in a 50 gallon DWC bin for mt 4th flower a week ago. I got an 18W industrial air pump and 4 4' flexible air lines and figured I was set to grow some massive buds. Such was not the case. After 2 days, the roots started rotting and the plants were sagging hard and a couple were drooping so hard that the stems gave out. I freaked out and went and got 5 gallon buckets and threw them in there, think they just needed more direct air to the roots. I also added 1 tbsp of 3% Rating: 5
