so i'm planning to build a pretty big box, (8 feet long, 4 feet wide, and 8 feet tall) and i was trying to figure out fresh air circulation. i've already budgeted in a thousand watt air coolable hps with a glass cover on the bottom.
my question is, by air cooling the HID lights, does that also bring fresh air into the box or is all of that fresh air just taken right back out without ever mixing with the O2 rich air inside the box? do you need seperate intake and exhaust fans for both the box and the light, or do the fans from the light also circulate enough air through the chamber?
would it be better not to get the glass bottom and upgrade the fans to circulate more air through the box? the problem i saw with this approach would be the distance between my lamp and the plants. after calculating the 8 foot total height of the box minus the 4 gallon buckets, minus the height of the lamp and keeping the plants another 2+ feet below the lamp, it doesn't leave me with much actual room to work with veritcally. i'd rather not screw with scrogging. anybody got any suggestions/experience/adivce they can give me?
much appreciated
peace
