Box update!!! thanks rollitup

now everyone has been extremely helpful with helping me build my first grow box ive taken every1s advice n here it is....
**anymore suggestions!!!!
***i plan on adding another florecent on the back wall and maybe the door

How about ventilation? Airflow = lower temps Looks like a good start tho.

GIARI

Bangin' setup you got chief.

make sure you have some airflow, temps will stay down and plants need fresh air moving through. Get a small intake near the bottom an a nice exhaust up top to bring cool fresh air in and get the warm air sucked out.

You probably don't need too much more light for such a small space.

i have an intake fan at the top of the back wall BUT ill make it an exhaust and put an intake in he bottom corner... i have the whole box sitn on some lil wheels could i make my air intake fan on the bottom floor?????

Yep that would work.

Warm air rises, so your warmest air will be at the top so it's best to have the exhaust up there sucking the warm air out, and an intake at the bottom will bring fresh cool air in to circulate through.

You don't even need an intake fan, a passive intake will work if you have a good exhaust because it will create a slight vacuum in the box, but a little intake fan is great too.

Just do passive intake... both fans exhausting from the top. Cut a few holes in the bottom, put in some pvc pipe... you would then be moving double the CFM since forced intake and passive intake will still get the same amount of air in... just trying to help make it more efficient.

for one big plant? it looks good man, lets see a giant bush in there now

looks awesome, i'm actually building my box right now

Those Fluorescents on the side are just taking up space, those only work well when really close to your plants, plus I don;t think your using the correct tubes. You should at least get a 150hps or 250hps, just vent it to control heat.

ne one have any link to a HOW TO BUILD A GROWBOX. i cant find nething anywhere. really dont want to spend 400 bucks
