rooms too hot! Help

So i have two 150 watts in my grow tent. One wasn't working so i only had the other one running, took out the broken one and fixed it. Turns out the heat from both of them is way too hot. In a room this small do i need the reflective walls? because i feel like it is not helping with the heat problem. I have just been keeping the zipper open now but that's not going to fly when i want to start flowering.

what are your temps? reflective walls are indeed desirable. what kinda fans do you run?

Also are your leaves turning yellow or is that the lighting? Like Scrog said...fans and ventilation?

yea fans and a good ventilation .. do you atlest have a nice 4 inch ventilation to vent that tnet ?

if you can take the reflective walls down .. do it .. they keep the heat is as well as they are reflective ..

but make sure the tent is light proof then .. a tube to a open window or a cool room for the intake might also help ..

also .. do you run it at day or night ? I run mine at night works well both for heat and time schedule as Im home when light is on ..


if every thing els fails look in to cool tubes or a AC

Whats the measurements of your tent? Are your 150's the all in one units with the ballasts built into the unit? It seems like a lot of light for that size space but its hard to know without measurements.

Do you have a centrifugal blower extracting?
