Hey everyone,
I have a small 2x2x4 tent that im using and I feel like im starting to struggle with heat and its not even warm outside yet.

My ambient temps of my room stay between 71-73 degrees. Inside my tent I struggle to keep the tent anyplace between 81-84 degrees. I do run the tent at a negative pressure to help suck the hot air out faster. I am blowing the warm air out into the room that im also sucking air into. I have my passive intake duct about 5-6 feet away from the carbon filter exhaust. This is where im grabbing my rooms ambient temp from as-well.
Tent setup
  • 2 300W Mars Hydro blurples
  • 6" AC Infinity Fan drawing air out the top into a carbon filter
  • 2 6" fans blowing air around the tent
  • 4" passive intake tube
I feel the tent only raising 10 degrees above room ambient temp is pretty good but im looking for some way to help bring that down even more. As it gets closer to summer I feel like I will be dealing with much hotter temps in my tent.
One thought I had was switching the blurple lights out for a Budget grow LED 130W (https://www.budgetgrowlights.com/collections/micro/products/series-3-lm301h-130-watt-dimmable-grow-light) or even a HLG 135W (https://horticulturelightinggroup.com/collections/kits/products/135w-qb-v2-bspec-led-kit) as I then should be-able to mount the driver out of the tent saving myself a few degrees.
Just wanted to get everyones take on what I should do. Happy growing!

6inch ac infinity should handle a 2x2x4 (feet) easily . The only things I can think is definitely try to vent outside it makes a huge difference and then also put the carbon filter on the suck end of the fan..

Low to mid 80's is optimum temp under LED.
The heat will be determined by the actual wattage. What's the actual wattage of those mars lights?
The lights you linked can reduce heat, less wattage needed to produce the same amount of light as the blurples. They will also grow better.
Drivers should be 90% efficient or better so they don't produce much heat, but it all adds up.
Use the exhaust air cool the remote mounted driver. :wink:

separate carbon filter fan from cooltube system and PULL through filter never push.
