My grow room

two 4x4 tents. One 3x4 tent. 6" intake fans on all of them. One 4x4 has a 6" exhaust and the other is tied into a hydro farm 4" high output fan. I'm running a 8000btu pg portable air conditioner. One 4x4 has a mars pro epistar 320 in it. The integer 4x4 has a 600w 6" air cooled mh/hps light with digital ballast, this is the tent exhausted with the 4" tied to the 3x4. The 3x4 has a 250w mh/hips built in ballast. All in all it's a super tight setup and the temps are nicely controlled. All the freezing temps I only run the Ac on fan low, keeps my room at around 73-79 lights on. Led tent usually sits around 73-75. 600w sits around 75-79. 250w sits at 75-77.

I'll post more pictures later

This is my 600w mh/hps 4x4. I ended up getting tent for $35 brand new unopened. The hood for $25 and the bulb for $15 brand new. I paid $65 for the ballast brand new along with a used hydrofarm inline 4" fan. The exhaust from the 4x4 is connected with a wye to the 3x4 tent... so essentially the 4" is pulling the air that is being pushed by the exhaust from the 4x4 while pulling from the 3x4 tent acting as the exhaust from the 3x4. These two tent exhausts are directed out of the window. As of now there is no intake fan in the 4x4 but with the vents along the wall it is pulling plenty of fresh air.

This is the mars pro epistar 4x4. Has a 6" intake and a 6" exhaust vented in the room due to almost no heat and I ran out of 6" ducting. So make soon I'll exhaust out of the room with that also. This tent does run much cooler than the other two with the mh/hps setups..

In the 3x4 I'm running a 250w mh/hps setup for now due to the fact my t5 h/o 8 bulb fried a ballast taking out half the lights. I will have that repaired or do it myself and want to run a two layer led/ t5 h/o 8 bulb setup to feed the two 4x4 tents. Like said before this tent has the 4" hydrofarm fan exhausting air out and a 6" booster fan as an intake.
