I've been noticing a lot more of this on blanket/mylar installation. 1 word you guys - velcro. Easy to re-adjust and remove.

SuperZero said:4, I would have more, but the sativa is everywhere. I start under 12/12 so most will be single cola style.
SuperZero said:That stuff looks like those sunshades you buy for your car window. I seen em at the dollar store and wondered, I'll probably pick a few up and redo mine, is that stuff pretty thick? I got dorito bags and other chips that I used, the best part was emptying em.
Budless said:Quick question. Are you guys using the fan in the light attic as a pusher or puller to get air in?
Budless said:Red uses the carbon scrubber fan for a puller for the growing area which has the double exhaust system running from it. The light attic only has one intake, one exhaust, and one fan from what I recall.
Red said:Technical Details:
Anyone can stick some lights in a box but it's up to the ventilation system to make it work right. The basic rule for ventilation is that the intake area must be 2x the exhaust area otherwise the air flow will be restricted.
The lighting chamber is cooled by a computer fan pushing about 38 CFM. The exhaust air comes out at about 82-84F, but there is little heat transferred to the grow chamber. The lights run about 90F inside the lighting chamber.
The grow area of the box is ventilated by the scrubber with about 10-15 CFM. The air temperature exhausted is about 1-2 F above ambient. The air exchange rate is optimal to provide fresh air to the plants while not stressing the plants out by drying from too much air flow.
