Root prune on the modules nearest the return mani......keep roots outta there and you'll be all good.
Hey everyone thanks for the comments/compliments!
I have (1) 8" fan for every 5 hoods. (3) total.
The A/C is a 32,000 BTU freidrich industrial window air conditioner. She's doing great with all 15kw, co2, (2) dehumids, etc.. come summer time i doubt i'll be lucky, so that is first on the "upgrade" list.
I'll take some pictures tonight for everyone for sure ... thanks for the interest.
