I have to add, that I too tried a few grows in the attic, tents wouldn’t fit because of the roof trusses, so I got busy with styrofoam furring strips duct tape, and visqueen, screwed the whole thing together and made a grow space up there. It took days to construct, still had all the problems of an attic, tight spots, access problems aways, not to mention the dust. It had ventilation and circulation inside, but didn’t monitor in any way the RH, boom powdery mildew.
Tried outdoor growing, heat and bugs got the better of me, got up to more plants than I wanted, and still didn’t get much to harvest. Started making salves and tincture and that’s what got me reading the forums and finally deciding to join.
It’s been much better for me since then, decided on a more sensible growing area, got one tent, then another then yet another. Along the years I’ve changed from T8 fluorescent fixtures, got a T5 fluorescent fixture, bought my first bluple fixture a “lighthouse black star”, then several others. I initially bought a metal halide 1000 watt fixture and never fired it up, cause I was too worried about burning down the house because of the heat and my futile attempts to grow in the attic. Last year I fought the temptation to purchase another more powerful (from what I then had) pre-made cob style fixture and took the plunge with a Rapid led cob kit. That has been another turning point for me, anyone on the fence, those lights (cobs) and the quantum board lights are the beginning of the future. I’ve just put into service a small two hundred watt four cob Cree kit light and that’s rocking it. Loving the community and sharing in it...
