my grow space is gonna be like 4x4x9 and i want to get hid lamps and i know i want three (one for veg 2 for flower) but dont know which to get for flower 2 hps or an hps and a mh or watts i should get if i do this
mh is used for veging. the hps is used for flowering. you will have to have some good venting to use 2 lights in that space. if you can aford it get a switchable. then all you have to do is change the bulb. do a temp test befor you put any plants in there to make sure it don't get too hot. you don't want to cook your plants. chech out the faq at the top of the page it will answer your questions.
thing is it has large shelves and i was gonna put more than 6 plants (3 veg and 3 flower) at a time so i was gonna put em like on top of each other
cause theres enough room for that and just get like 4 fans to keep the temperature down
I have a 400w mh and built my own heat buster hood that worked real well.
For my next step I was going to rebuild a new hood to hold the 400w mh plus a 600w hps and during flower I was going to run both lights. During veg I was going to run only the 400w mh.
My room is 3f x 4f x 7f and my goal is high quality weed to me 1 oz of good shit is better than 1 lb of low grade shit
