my grow space is 20in deep,30in wide and 4.5ft high. i wanna get a hps light and i was wondering how big are they,what are the heat outputs. i dont know what one would be perfect for me 250 or a 400watt. how many plants can i grow in my setup with a 250 or a 400watt hps? also what kind of venting unit am i gonna have to install? i cant vent through the top cause theres a second level to my setup. i only have one side to vent out of.
