Yes, there will be tremendously more heat with a 1000W HPS than with what you've currently got, especially in such a tiny tent.
I was thinking it would be. I had it in a 4x4x 6 and with the doors open it was close to 90*
I had plans on using the spare bedroom to grow, got going, but my nephew basically got abandoned by his parents so I give him the room, which put me in a walk-in closet. Just looking to improve my set up to be more efficient.
That 4x4x6 tent is more than three times the size of a 2x3x4.5. You're talking 96 cubic feet compared to 27 cubic feet.
Ya, I can't handle any more heat, that's for sure. I leave the veg tent open full time and open the flower tent when lights are on and if I close the closet door it's in the high 80's
Well I do, but only into a carbon filter inside the closet. I've got to bite the bullet and cut a hole in the floor or ceiling
Size doesn't mean anything for the inline. What is the actual fan you are using? If it's a basic 4" inline duct fan that you can get at a hardware store then that is your problem. Those don't push nearly enough air.
I ordered it from eBay, they were pretty much shit. Basically, I need to overhaul the room. I just kept piecing it together thinking it was temporary and id move it into my larger closet, but then my gf moved in and I've been a really horrible care taker for all my girls. I guess it's time to fix the environment as well.....fuckin Carole Baskins screwing up my grow.
