Ventilation is not an issue at the moment. the temps stay at 75!!! :D yeh im definitally not using anymore ferts till they get alot bigger. and i think i mixed it wayyyy to strong
I killed off the other one.
but the healthier one I clipped the tips of the leaves and its doing just fine :jointsmile:
I got a new plant germing.
I want to set up a new veg box and a bigger flower box but I dont have the space.. UNLESS ITS STEALTH.
you still need ventilation. fresh air helps your plants breath. as for powering pc fans, find an ac adaptor with 12v dc output.
good job with the lights! your plants will thank you.
if i put computer fans on there wont it let light out the backside of my desk?
the trick I used was: i got a small rectangle cardboard box cut a hole on one end for a fan, and another on the back. it works kinda like the trap under your sink, creating a 90 degree duct for air that light can't backtrack through. i just mount the box with the fan pointing down and duct tape the seams. you could also use flexible tubing to achieve the same effect. here's a diagram of my "light trap". it's my own design so you could probably make some improvements to it. but it works really well.

yeah just put it on the back. the flexible hose should work well for you. PC fans are really quiet, and most manufacturers give detailed specs on pc fans including cfm(how much air they move), as well as db level(how much noise it makes). here's a really good site that has awesome prices in addition to all the specs.
computer case fans

i just cut a whole in the top back and put some air duct through it and its letting a good bit of heat out. are you sure i will need the fans?
