http://www.youtube.com/watch?v=gQnyWtxjI0w here's another vid at a nice grow

they look cool. just wondering if the science holds up?http://www.hydrotechhydroponics.com/content/air-pots

it's obviously not to scale but you get the point. hoping to get 5 nice babies in there:leaf:

well the plan is im going to use a cool tube and ducting out both sides to cool it with its own 6" 240cmf duct booster so most of my heat should be gone there. then ill use the 4" inline fan filter combo to scrub and exhaust straight out.

i was planning on using this.... http://www.ebay.com/itm/4-x-14-Carbon-Air-Filter-Value-Combo-4-Inch-Inline-Fan-Exhaust-F016-/281102466057?pt=LH_DefaultDomain_0&hash=item4173033c09 it says 190cfm

great info man!!!!

one other question..... i building from wood, if i use cocking or something similar to seal all the corners. will that release toxins when heated? or is it safe for my babies?

perfect thanks

90 degree angle on what?

i am building a wood grow box. i was wondering what are some ways to make sure light dosent come in my passive intake? i will probably have 2 4" holes. and i wont have any room to run ducting outside of my box from the bottom.

really, that much?

if I use a 4" inline fan and filter combo how big should my passive intake be to ensure proper air flow? the space is 44"X36"x75". thanks

I am building a box, it will be around 45' across x 36' deep x 78' tall and I will be using a hybrid suntube-reflector inline cooled 400w hps setup (the closest one I could find)...

or is it better to hook the light up to exhaust and pull heat out with a normal passive?

like this?

since im using a cool tube could I have it hanging vertical so that the cool air will come out the bottom of the tube?

drawing up plans for a grow box.let me know what you think, any advice? I will be using a 600w hps/mh digital ballast with 6'cooltube, 6' exhaust fan & carbon filter. the maximum size I can build45'x36'x79' I plan on 4 maybe 5 babies...... I have never seen this before but I...
