The title pretty much says it



this is what I got to work with, so far ive got most of the inside covered in mylar.



I just gotta cut holes for the ventilation system which costist of a coupe 4 in desk fans, and there will be another fan inside to keep air moving.

wheres the test with the light in

I have a 400w with a built in ballast in a closet that is 2' x 3' and 6 feet high and I had to get a bigger fan to keep it cool. I believe you have the same one I do and it is rated for a 3'x3' space without getting too hot.

You will likely need a 6" inline or mixvent fan exhausting air through a carbon filter to keep the smell down and the cabinet cool, something in the 300-400cfm range at the least. 4" desk fans aren't going to cut it.

Even if the ballast was outside the cabinet, and the 400W HPS had a cooltube with a dedicated exhaust fan the cabinet would still need a decent inline/mixvent exhaust fan to stay under 100F.

Before lining the thing with mylar it'd be a good idea to caulk all the joints that don't move to keep the thing relatively light-tight and air-tight so intake air is only pulled in through your intake hole(s) and not every little crack. Also use some sort of filter on the intake so dust & junk isn't being pulled into the cabinet.

looks like a great start man, I'd go ahead and second the extraction/filter maybe even a 4inch will suffice given your running temps, but remember the temp will change
when stuffed w/plant matter too.

Don't forget to watch your water temps if you're doing hydro. Also, I recommend ( probably more in the future ) an Arduino setup to monitor temps, humidity, light, etc. That way you reduce your interaction with the plants to a minimal.

I know its been a while but im back with an update

my one little seedling that just sprouted today....hope its a girl
got another seed germming atm. I definatly still have work to do on the cab to...light leaks like no other and still need to upgrade venting and air circulation, neither a problem for vegging but soon it will need to be fixed.
