The plants look fantastic, definitely stealing the box fan idea to cool my LED Drivers too.
Do you run any predatory mites or other forms of insect ipm like rove beetles?
I'm starting a 4x8 bed in place of about half of my grow space going from 30g pots to there, I never really saw a boom in insect/mite population in my pots I'd see the occasional one here or there but I don't think it's really enough to consider an active population. I was considering buying some mites and rove beetles to get over the early problems and then was going to throw in some nematodes closer to when I flip to flower to really try to jumpstart the cycling. I'm also planning on letting it sit and the cover grow for about 2 months before growing in it. If I plan to let it sit do you think the mites, springtails, and rove beetles should get added as soon as there's decent cover crop or should I wait until I do like the first chop and transplant? I know there's not really a good way to skip building your soil food web but I'd like to push it along as much in the right direction as I can.
