so i have a 2x3x6 grow locker. i was sold a 1000w hps and i asked the guy if it would get my locker too hot and im at 93f im about to install a carbon filter at top to reduce some heat. so i need some help to get through this. what can i do to lower the temo 20f or should i get a 400w hps and will that produce the same amount of yield.
