some input on lighting please

Ok im building a new grow area and im torn between what lighting to get the are is 46"L x 31"W x 45"H. Basically i would really want to run a aircooled hood with a 400 mh/hps setup is that gonna be possible in such a small space or should i just go with some t5 lighting thanks

Yeah you will have enough room to have the 400 watt mh/hps lamp. You could use both and have the t5 to supplement side growth!

Thank you I will probally go with the 400 and do 4 plants it will be perfect!

400 should work fine. Just make sure you spring for a decent fan to pull the heat off of it. If you try to get by with a booster fan you will end up buying an inline anyway.
