Suggestions for # of lights

A room that large can handle way more than 49 plants.
At the very least, I would double that number.
As for lights, that space should have at least (8) 1,000 watt HPS. The euro-systems dual 600 systems are also very cool. 2 lights on 1 ballast. You could do maybe (6) dual 600's.
Of course, all of this depends on how tall you want to go, and how fat you want your buds.
Your power bill will go way up!
If that is too hardcore, split the room in half...

 

The average single family home has 45 light bulbs in it at an average of 75 watts .....thats 3375 watts for lighting alone replace those with 13 watt CFL's at 585 watts and ya' have 2790 watts to "Play" with B4 ya' see it on the bill

Are Ya' lookin twards Perp. harvest system?

Are Ya' gonna go start (seeds) to finish (Flowers) each time?

Good post man.... I am going to do it this week. Never thought of it that way. +rep

 

Thanks fer' the rep Bra'.....I make all my own power up here (we live WAY off-grid)...so if there is a way to save power I know it ...lol

 

I wouldn't bother with an mh if this is your bud room. But, yes (4)1000 hps would be good.
4.5 sq ft / plant is quite a bit of elbow room. Go with big soil containers. 5 gal should be good.

 

Well if this grow is actually for personal use then I'd reconsider how many plants I would grow, cause 49 plants yielding just 1/4 lb. would result in a harvest of 12 pounds. With 2 1000 watters you could grow 8 very nice trees and get 4 lbs.

 

I would consider using CFLs so your bill doesnt sky rocket, they put out a lot of light 42=150 watt. 1 1,000 watt HPS is said to fill a 4sq ft area so... yeah.

 

thats 150 watts incadescent. but the wats isnt a good measurment of light any ways. i would not suggest cfls for such a large grow it will still make your light bill go up, except for the clones maybe and or secondary lights. also with cfls they say to use about 100 watts per plant and alot of people use maybe 5 of those lights per plant that would be way to much for you.

EDIT: cfls work great for small grows but not for big grows and it also says if you use cfls to use 100 watts for the first plant and 30 watts for each extra plant but i still think this is a bad idea for you

 

that is goin 2 be one hell of a grow...let us see some pics if u get it up n running
