Just an update & a couple of more newbie questions. Got the (2) 320 watt kits assembled & tested them, these things are frigging bright ! Waiting on my 6"carbon filter & 6"exhaust fan to arrive (supposed to be delivered today), then I can install them & get the lights hung. My AF beans have arrived as well & I will be using Fox Farms soil this first attempt at a grow. One of my questions is with the lighting, I would assume that I will need to cut back on the power of the lighting somewhat when the plants are young correct ? Any recommendations on how much to dial them back & what height I would need to keep them above the plants ? Still reading, trying to learn the basics & still have a few more things to get ordered. Thanks Guys !
