I do realize they aren't the best conditions. This is my second grow the first one was succesfull up in the attic. But was only Fluros/ cfl's. And well the weather hadn't gottent real warm yet. So a venible hood and an inline fan wouldn't be enough to keep the plant happy? I really need some help here before i go buy my light system and fan/fans.
Here's what you need to do Tool46. Figure out how many square feet of plants you want to grow. Calculate how much light you'll need to accomplish this many plants.
Put the lights up and run them for a couple of days. Measure the temperature of the grow area with the lights on at the hottest part of the day.
Add ventilation or a/c until the temperature stays below 90 degrees F.
It's that simple man. Make sure you add an appropriate amount of degrees for what your max temp gets to in your area.
If it's 80 F outside and you need one vent fan to bring it to 85 F in the attic, then if it gets to 100 F in your area, plan on either adding a/c to your area or better ventilation.
The goal is to keep the temp down below 90 degrees F. You'll have to put your lights up to see what effect they have in your EXACT situation.
Good luck to you man. Let us all know how it goes.
