HPS Lamp Question..

hey j.a.b
as far as nutes i use gen. hydro. 3 part because they're very forgiving . but i do hydro , to use in soil i think they recomend 1/4 strength .

1000w lights are a fucking waste of money and I can tell you that catagorically. Well, if you have the luxury of having 4 or 5 of them in unison no their not. But if you have a situation where you can either use one or two 1000's or a combination of lesser wattage lights to make up the desired lumens. Always, always, always use more of the less intense lights. You will generate more light and illuminate a larger area.

Thanks everyone for your replies, we've 14 seedlings ( now i've squashed 1 !) which we want to grow on , clone from them, n what we sell buy more lights n better fan n extraction, the £600 we have allocated is to basically get us going,we will add on and tweek obviously. l am worried about messin it all up, thats why i'm here pickin everyones brains, would plants grow just as well under the 600w, maybe three of them,and would yield be roughly the same ? We are growin northern lights, hopin to get some lowryder, more to see how they grow as i know( i think lol ) u cant clone from them.
We will be using the spare bedroon, the cellar (basement) is bigger. 17'x17', but i'm concerned the heat from just the lamps won't heat it sufficentially.
I've also read that organic nutes, that u can't overfeed, am i right or totally wrong. I don't wanna kill my babies through kindness :o

Are you speaking from experiance Mega ? kinda sounds like you are lol

Alot of research mate, trust me on this one

So how many would you suggest for an area of 9'x9' ?

i agree with mega to a certain extent. obviously if you have more light fixtures you will have more lighting. but if you put toghether the amount of 5 600w lights, balasts, and reflectors you will probably spend more then 3 1000w lights, balasts, and reflectors for the same wattage. also the higher the wattage the faster they will grow and the more penetration i belive. its up to the grower and its about the same in the long run (besides growth speed) i think. theese are all educated opinions but my plants grew almost two feet in one month.

i agree w/ part of what mega octane 12 is telling you , but do consider how tall the plants will get when deciding between 600 / 1000 w. lights . penetration is very very important . lots of 400/600 might be nice for cloning tables / scrog / sog but if they end up trees the lower parts of plants are gonna be fiendin for light where they wont be w/ 1000's .
do lotsa research and learn from everyone on here's mistakes so you don't havta make them all yourself as they can be incredibly costly .
peace

USE the best 600 WATT HPS lights you can find

Also you might look into using a track

It is also true that the 600 watt hps system give you the best watt to light ratio. The new bulbs have a fair amount of blue and do a decent veg cycle. I used two of them in tandem in a 7' x 4' space and got great results. I did my veg cycle under fluorescents however.

I have seen 400 / 600 watt bulbs in full action, they are very dim imo.

If you want big plants stay with big watts per bulb, SOG of scrOG 600 / 400 would be ideal.
