No then they start acting all giggly and silly and it's not a pretty picture. I think you are right as well and it is heat......200 is certainly not anything near overnute level anyway.

Interesting your are talking root rot here.....I've been having quite a few issues with it myself lately due to my cannazym getting too old and some other lovely tricks I pulled on my (now dead) plants. What enzyme are you planning on or just going to pick tidbits? Let me know what you end up using.
