@KeeBeeper, I do use it..but it's not really that important….what's really important is the air renewal…in and out 24/7…that's always on… and the temperatures and humidity…that's what makes the difference.
Think i just had a little sympathy anxiety thinking about all the work for 36 plants. Hope it's a sog grow... not so overwhelming in that regard, if so. I did 16-20 a few times, non-sog, and it was crazy.
@00110001001001111O, it seems you don't see my updates... I don't do transplants... and I've been working this way for a long time... and you can see the results more than just the photos.. you would realize.
