Hello everyone. I am new to the forums and am also a grower with minimal experience. I have started 3 grows over the last year and a half. No success with the first two, due to environmental conditions. My last was fair but, way short of what I expected. I had a grow room and was using...

Well folks this is my second grow and I am again growing autos. I chose Dutch Passions Big Bang auto and Auto Bomb because I wanted to see if I could achieve high yields as others have. My love for autos is strong I will probably stick primarily with them until I feel ready for regular plants. I...

I built a 2x2x4 cab after a half assed attempt at growing some bagseed. Tried experimenting w/ CFL's at first, but I was having some serious heat problems due to my ignorance and inexperience with proper ventilation (and killed a couple seedlings in my hubris). I've been lurking on here for a...

Hey fellow growers, I know that it is near impossible to have a completely airtight grow room. But i Live in an area where the pollen from the ditch weed is everywhere...i mean everywhere. Can anybody offer suggestions as to how to make my grow room sealed enough to keep this pollen from...

Quick background about me; I am an online professional poker player so I have a load of free time on my hands. I needed a hobby and stumbled across this place a few weeks ago. I've become fascinated by the growing and journals on here so decided to give it a go myself. I started reading here...

I have my first grow box in a plastic bin, the ones that everyone buys right after Christmas when they're on sale ;) I have the lights set up and in the process of installing the fan and exhaust. Since I am putting this box in the attic, and I am in the beginning of a long summer in Florida, I...

Hi, I have a grow tent which is a 3x3x6.5 model. I've just ordered a 600 watt cool tube and need to get some ducting; challenge is what size to buy. My set up looks like this: Fan — 5" Port holes — 5" Carbon filter — 4" Cool Tube — 6" Three different sizes I know, kind of sucks. I...

I had the great idea to convert a mini fridge into a grow box. This will be my 3rd time growing but I've never built a grow box. I need help and ideas on the wiring part of it. I need to know how to install a pc or computer fan as ventilation and how to install the lighting. The simpler the better.

I know this is a stupid question but what is the best position to put a fan in a grow room? above the plants on the side or beneath them? I know that the plant breaths/exhales air from the bottom of the leaves. Does pushing air from the bottom of my room and up the plant help the plant or does...

I have my first grow room. It is a spare bedroom, which is 9' x 15'. Currently I have 8 plants, with 2- 48" fluorescents (well 2 bulbs per light fixture). I plan to eventually add 2 more lights, same type and double the number of plants. I have a cold air return in the room, along with one vent...
