You are right, a fan won't actually lower room temperature. So what, were you planning to turn the closet into one giant fridge?
The way I see it, who needs to worry about temp and humidity, as long as nothing catches on fire! This is not some big time operation where such details might have a big impact on total yield (others care to disagree?). The main thing here is that you get yourself an HPS (high pressure sodium) lamp - no flourescents! I would say absolutley no more than a 400W, perhaps even a 150W HPS will be sufficient for that space. Also, don't bother with hydroponics - waste of time + money if you ask me.
So that hole in the wall, does it go directly outside? If so that sounds like your best bet for extraction. If not then I recommend reading this link http://boards.cannabis.com/growroom-...on-filter.html which shows you how to build a device to erase the weed smell.
So my advice to you is do your homework but keep things simple. The main two priorities with any indoor grow are that it's air-tight and light-proof. Theres no need to build a box for the closet if you treat your closet like you would a box.
Thats pretty much all I have to say for now, I am an electrician, only one year older than yourself, but living in the UK, so if you have any electrical related questions let me know.
I couldn't help wondering, which strain do you plan on growing?
GrowmanSparky Reviewed by GrowmanSparky on . Enough closet space? This is an illustration of the closet measurements. As you can see in the crappy photos, the roof slants down at an angle. My questions are: 1)With the closet cleaned and empty...is there enough room to harvest a few plants at a time *veg*+*flowering*? 2)How can I control the temperature/humidity, without adding any holes in the walls? 3)Do I just need to go ahead and make a grow cabinet to fit the size of the room? (If I need to install aircontrol and stuff into the walls....I will Rating: 5
