430w or 1000w hps for 5x5 ft growroom?

like the title says should i get a 430w hps or 1000w hps for 5x5 ft growroom?
any help would be appreciated

Defidently a 1000 watt! A 430w would only be bout 20 watts per square foot which would seriously suck. Nothin would grow right. A 1000 watt still isnt really enough in my opinion because it would still only cover 40watts per square foot which is just enough. 70 to 80 square per foot being optimal. If your planning on filling up the space corner to corner you need at least 2 600watts.

600 is more efficent of all three sizes, more lums per Watt, best bang for the buck.

Even a 600 and a 400 would be better than a 1000. (less heat, better light distribution, can get the lights closer to the plants)

I ran two 430s in a 6x6 and pulled allmost two lbs.I know run a 600 watt in that space now.I leave the 430 in therewith the 600 during the stretch and at the end of flowering

your right, kind of. the 1000w is best when heat isn't an issure, which it easily can. 1000w in a cool tube is best by far. and as far as coverage goes.. it will penetrate the canopy way better than the others. you could do 2 1000w cool tubes in a 5x5 but 2 600w in cool tubes would be the most effective for the price and space. you light coverage is heavily dependent on the reflector, especially if you have only one.

that right there is perfect for 5x5 if you can vent it good enough and dont need a cool tube

Cool tubes are terrible at putting down an even caopy and are famous for blowing bulbs premature.Two 1000 watters are overkill bad and maybe two 600s are too.My power is high as hell now,if I burned two 1000s Id be broke and in jail

go with an cooltube and the 1000 watter. in that area you should be able to pull a p easy with the right strain and number of plants

I don't know how you could consider a 400w lamp. Simple answer if those are the two options. Lay it down with the 1000w.

My buddy has a 5x5 with a 1000w and it's got the potential to pull down some decent yeilds. A pound would be a good STARTING point. You should be able to yank down a bit more than that if you can find a good strain and style of growing that works well in your space.

600w's are great, but you need a rectangular space or 4x4 or smaller. I have a 4x4 and I'm considering swapping to a 1000w lamp and ballast from my 600w. It's just not quite enough coverage.

Buy you a nice reflecter and a piece of glass,Ive got three cool tubes laying in my bedroom floor.Sunlight supply hoods with glass yield a third more than those tubes.If you run those tubes you might as well just hang a fucking bulb in the middle of the room, they have no downward light penetration into the canopy.

Oh yeah...good point. I meant to add that, get a good reflector. And get one that meets your needs, not the cheapest one or the most expensive one. The one that is designed to cover your area and shape. Do some research on them and don't use a cooltube.

Cool Tubes are really only good IMO when you make them yourself and only because they are cheap, not because they work well. You wouldn't catch me buying a 1000w ballast and lamp and putting it into a cooltube. should've just dropped the $100 to get the reflector. your yeild will more than pay you back your $100.00.

try hgtsupply for good lights and stuff

thnx for the input! another question, what is the difference between using a 120v cord or a 240v cord for a 1000w ballast?

-I would use the 1000w it is perfect amount of lumens for the space you have, unless you want to buy two light systems.

-The 240 pulls less amps..ie my sun system ballsts pulls
~6 amps at 240 and 9 at 110.

uhmmm....really? I'm not an electrician, but wouldn't that make the 110 much more efficient whichi is counterintuitive?

240v x 6 amps = 1440w
110v x 9 amps = 990w

eh? How does that work? Did I miss something?

They both use 1000 watts.. one does that by pulling more amps than the other..there is some differences in opinion of whether or not you actually save energy with the 240, but I had mine wired by an electrician friend and his opinion was that the 240 is more efficient

So then obviously your first numbers weren't correct. It is indeed about 9 amps @ 110v, but at 240v it would have to be more like 4 amps.

lol, okay... you know your suppose to circulate air threw them right. also, i wasn't talkin about some cheap refelctor, but a nice air cooled reflector.. lol 2 1000w and you'd be in jail. thats funny

what kind of cheap ass reflector did you use.. air cooled reflectors have grown some of the best grows i have ever seen because you can put the light so much closer than an exposed bulb.. i see you have had trouble with them, i understand this. but one bad attempt does not justify you putting something down like that. Its all about the quality of the reflector. just a cheap reflector does not do anything and yes, lol, just hang a fucking bulb in the room.

I think your argument should be against cheap reflectors. not a general design..

Another thing is, if you get a reflector and put a piece of glass, sealing the bulb with no circulation, this will indeed cause a premature bulb failure. you contradict yourself. Its all about keeping the bulbs cool.

OK..I'll split the difference with ya...you made me take my high ass down stairs and check..

here ya go
110 - 9.5 amps
240 - 5 amps

see pic

so does that mean that the 120v and 240v are basicly the same?
