So I've had two PC's sitting around my house and I decided to stitch them together, the result was this:
http://forum.grasscity.com/attachment.php?attachmentid=455910&stc=1&d=1283738490

This is 32'' tall 7.5'' wide and 16.5'' in length as you can see in the image. I am using an actual 200w CFL lamp so its more than enough for 1 plant.

My main question is the ventilation, I read the ventilation FAQ in the forum and the do NOT recommend intake fans. I have two intake fans one blowing from the bottom right and one blowing on the plant from the left. Should I seal one of the intake fans? Should I change my ventilation system entirely, by removing both intake fans?

Another question is should I more the plant closer to the lamp? It is now 4 days old, a lowryder #2.

Also, I use a fogger to increase the humidity in the box and feed the plant as well, it that good enough or will I need to water it as well? The soil keeps staying moist at all times, evaporating about 200ml every 6 hours.

I have alot of free space, how should I be using it? I was thinking of making some DIY light traps and odour filtering.

Any input would be much appreciated.

bump. Any ideas whatsoever? Should I seal up the left fan (making it just a circulation fan) and remove the bottom right one to leave a plain hole for negative pressure? :confused:

Would it be better like that? Any ideas will be much appreciated.

i have a cab with dimensions similar to yours, and Im running 190 watt CFL. started with 2x 80mm for intake and 2x 120mm for exhaust, found that was not nearly enough and couldnt get the temps below 92.

Currently, the temps in my box (which is very similar to yours) hang around 85 w/ 190 watt CFL. In order to get the temps down, I had to ADD 1 80mm intake (for a total of 3) and replace the 120mm exhaust fans with a 4" vortex duct fan. I found that the 120mm fans dont cut it, and couldnt keep enough air circulating past my bulbs to keep the temp down. I managed to lower the temps down to ideal range by adding 3 120mm fans blowing right across my CFL's to keep the air moving. I should mention, I was desperate for a carbon filter so I bought the vortex fan out of necessity so I could pull through carbon. I imagine its possible to get 120mm's to work with carbon, but it will be very hard to manage your temps.

Just some advice from someone who is half way through his first grow:wave:
