I am new to the site and was just wondering which is the best route to go. two 400watt hps or one 600watt hps. my room is basically 6'x6'x8'. just wondering if anyone can help me out.. by the way i love this site for the info that i have learned. thanks
haha no i don't live in a bathroom. thats the size of my grow room.i wish it could be bigger but i guess thats as good ad its gonna get for me. i was just trying to decide which would be the better way to go. two 400watt hps or one 600watt hps?
6x6 = 36sqft, ideally for flower you want 50w/sqft. a 600w light won't adequately light that space. You want 1800w to flower that space right, 1000w would suffice if you cut it down to 4x4.
Id use the 2, 400mh, But as a larger room grower Ive got 4/400 in a 25sqft.. No problems with coverage.. but all lamps are not lit,for full 12 cycles. This type of set up takes alot of practice,. but helps reduce energy bills and still gets super bud.. and theres a low lighting system CFLS, and plants seem to respond to the lows to highs light coverage.. But I most recently began to do this timer induced light mover.. I wish I wasnt so stoned but Id explaine more.. But I thinks its self explanitory.
Hey Kingswib! Ya gotta put a little more effort in and getcherself 3 x 600 watt hps's. I ran a 9 x 5 room with 3 x 400 watt hps's and it yeilded 6 oz every other week. Now lookin back in retrospect I figure I shoulda been usin 600's. Try 3 x 600's. Im usin 4 ofem now. If your dead set on doin one or the other, 2 x 400's or 1 x 600, Id advise you to go with the 600. That way when you get another light you can get another 600. You shurly will want more light later on. Its human nature. Get the 600's. Like Orison say's, 400's are a bit harder to work with. The 6oo's are easier. I dont think 400's are very effective anywhere after 14" or so. I think 600's are good for at least 18". This is really important when you consider the tekneeks youl have to use to keep your plants trained under your lights. This all bein said, it all really depends on how youl be growin. --Hey Howdy Orison! G-Mornin Brudda! Good to see ya up this time a mornin! --I dunno. I figure a new grower will prolly do better with the 600's. Itl be less work for him.
thanks for the help. i think im just going to stick with my two 400's and see what happens. :cheers2:
I used to use a straight, 1000w in the 25sqft. But you get alot of dead spots. not full coverage.. and its somewhat wasteful... the 2 400, are good.. youll have some space to play with imo.. could use a bit more light.. as noted above but still your gonna have very decent coverage..
Yea, he'l do good with that. Mabey he could setem up about 16" offa his farthest wall from the door. One to the left and one to the rite, 16 inches offa the wall and about 3.5' apart. Hel have some nice room to work.
so far so good. i hung the second 400 and it seems to be lighting very well. i noticed new growth on all my babies. another quest how far would you keep the lights from the crops? what is a good temp for my room? mine stays between 70 and 75 degress f. is the good or should it be a tad bit warmer?
Those temps are pretty much perfect... don't change a thing... with a 400 you can get the plants pretty close to the lights, 8 inches give or take (more when they are young), less if you air cool them....
