I’m a little thrown back by the attitudes on here recently. I mean let’s not pretends that 30 plants and 3000k of lighting is huge or Is not doable by a newb. Or that it’s unmanageable, or that Updog is the key to success here.
obviously 10 315s is ambitions. but it’s just a plant.
To the OP
tomake things simple go with amended organic soil. Either build your own or source something quality. Don’t get over complicated.
with your space. Dialing in a room takes time. I would recommend building and running empty for a few days and watch your swings in temp/rh.Things might change slightly when plants are in space but at least you know what’sgunna be your biggest hurdles.
Sometimes you gotta dive in, headfirst and hope you come up. I’m in a situation where I’m expanding exponentially and really feel lost, but things always seem to work out. Just gotta stick to the basic and listen to the plants talk
