will this be too hot?

im planning a box for my autoflowers, it cant be more than 90cm wide, but wanna limit the height to 120cm. gonna have an outtake with 240m3/h and an intake of 4x 4" pc fans. there will be one 250w cfl red spectrum and 2x 125w cfl red spectrums. thanks for the help, but it would be good if people who comment have a similar/had a similar set up. thankyou

anyone have even an inkling? will be 500w of cfl's , 4 pc fans for intake and 240m3/h out take. Ive never used intake or outtake before so the m3/h means nothing to me. Does thhat sound like it could empty a 1 x 1 metre box of hot ar pretty rapidly? thanks

well so i calculated that it should 'empty' the grow box in 15 seconds, which is pretty fast. Im just really scared that the 500w will b too much in such a small space. But with my extraction, it SHOULD be a healthy temp for my babies to grow ?? please help as im planning to order my new shit tomorrow

Sounds like it will be okay! CFL's don't produce very much heat! But who knows till you try!

yeah i had just a 250w cfl last time that hung in the middle of a 1mx 3m cupbard. I used bin bags stapled to aluminium heat blankets to keep the light from getting out. no itake or outtake just a desk fan. and it got quite hot in there. im hoping my new set up will be much cooler, alough im goin into a smaller space with twice as much watts but yes, ill never know till i try or someone has done a similar thing!!
