cool cheers guys

Get the 600 watt and stick a Hortilux HPS bulb in it. You could veg and flower with the same light. I do with great results.

a 600 watt hps light is said to be able to cover a 6'X6' area. I think that's a little high. I would figure on 5'X5' for better results. As far as how many plants, you would have to consider how big your gonna let your plants get. I keep my plants short due to height restrictions. So I grow SOG. I could get 30+ plants in there easily. For a "normal" grower without height restrictions I would say you could get about 6-9 plants.

As far as that light you linked. You won't be able to vent that hood. Keep in mind that a 600 watt light will get very hot. Your gonna need to be able to vent the heat especially during the summertime. I also suggest getting an electronic ballast. They are more effecient.

fillabong420 · 01-12-2008, 09:38 PM

well how many fans you reckon you would need to vent that beast in a 3x3 wide and 8 foot ceilin? and thanks or the plant number stix!

At least 2 4" with good squirrels on them, one high,with a cannister on it. One low for intake. Unless noise is no issue :-)

lol boss, im sorry i dont follow.

are you saying one high and one low for like circulation? or am i reading too much into it? hahaha because i dont see where the squirrel fits in to the equation

let alone the cannister.

Boss · 01-13-2008, 09:31 AM

Low intake for cool air from the floor, high exhaust to take warm air from the top, with a carbon filter on it. :-) Squirrel fans :-)

Stix · 01-13-2008, 08:17 PM

I would agree with boss. I would keep your exhaust fan at about 100 cfm and your intake around 80. Just make sure your intake fan is not stronger then your exhaust. If you had more air blowing into your room then was exhausted your house would begin to stink. And we don't want that.

72 CFM would replace the air in your room every minute.

If price was an issue, you could probally use regular bathfans that you can buy at lowes or Home Depot. The smallest bathfans available are 50 cfm on up to about 130. I'm pretty sure they sell 110 CFM fans there as well. A bathfan would work fine for the intake, but keep in mind about your exhaust. If you plant on running a duct to vent to the outside of your house then a bathfan wouldnt' work. You would need an inline fan. That way you can have your can filter which connects to your light with flex duct. then a flex duct from the other side of your light to your fan then a flext duct from the fan to possibly a dryer vent mounted on the side of your house.

jesus chrsit. lol thats sounds like a buit a of work.thansk stix and boss. thats deffinitatley appriciated help, you dont think two reg house fans could do the job? if i were able to somehow get them into grooves on the panel for the door?only cause theyre free to me. lol i have to ask man.lol

Boss · 01-14-2008, 01:04 AM

I used 4 computer fans for my intake, and a bathroom fan from Depot (19.99) and built a carbon filter that fit in the frame of it.
