DIY grow cabinet - First grow

[LaidBackLeo87]

so this is my first official grow, ive made attempts in the past but i never finished through, and i now have better resources to take an honest go at it. im using a marshydro 95x6, 2 60w CFLs, and 4 27w CFLs.

basic frame using 2x2 and 1/2 in osb board

lined with shower lining and frame beefed up a little bit for stability

4in exhaust fan added to top

insides caulked and wheels added to bottom for easy movement

lights set up and plants inside (ill be ordering the adjustable light hangers off amazon, LED is kind of far away from plants about 34in, id like to bring it down to 20in)

a little bit of light leaks but i am using a black out curtain that was lying around, draped in front it blocks all light.
if anybody spots something that could be changed to lower my temp any advice would be appreciated, because the 4in exhaust fan isnt really cutting it, within 4 hours of running the temp inside was at 82F, so ill have to figure something out maybe put another fan in top to exhaust? or flip it around and make it an intake fan?

You will find that small areas just heat up faster than larger areas. I have theories, but the reasons why don't really matter, it just happens

whats your thoughts on two exhaust fans vs one exhaust and one intake? cause im going to have to buy another fan im just wondering if i should make position it to exhaust the hot air, or draw in air from outside the box?

You want to have an intake cut in near the bottom of the box. That should pull in fresh air and the exhaust will get rid of the stale air. That should help some with your temps.

Do you think a 240 cfm intake would wind burn the plants if i put the fan near the bottom of the box?

Maybe idk, why would u put a huge fan on intake?

 

[bunkbudz]

You can use a fairly small fan on intake if u have a decent fan on exhaust

Really I'm just being a bit lazy, i just don't wanna have to take the exhaust fan out (65cfm) so i was just curious about adding the 240 cfm intake

No need to remove the 65cfm. Simple stuff:

After our conversation last night i think I'll just add another exhaust fan because of temperature, i just wanted to answer his question as to not be the anti social new guy . Your the man doctorgonzo!
