How many plants under a 600w HPS?

Hi, as you all know I have a 600w HPS in a cabinet lined with mylar. Im just wondering how many Lowryders Ill be able to grow under there.
By the way, I can fit 6 in, but depending how well they do in the small pots Id be able to fit 8 in.

I wouldn't go more than 4 though, just a thought, but it is better to have some room for them to grow and they also receive better light penetration, due to less foliage...imho

lowryders, I have not grown...from what I know/read about them, perhaps they are small enough for 6-8...I would err on the side of more room...lw

The general rule of thumb is .5grams/watt under ideal conditions, no matter how many plants ya have in there. Also, do ya have Sativa's or Indica's (or a mix, for that matter)? How's the ventalation?
Personally, I would go with 3-4. If anything, it'll give ya a good idea of what to expect next time without really hurting yer plants...

:)
Fly High!

Cheers guys, after this grow Im gonna sell/trade my 600w for a 400w, because over summer the temps are gonna get way too hot, even with the window open.
Mind you, I can always plant them in the garden instead and have some nice outdoor bud.

I tell you i have 400w on veg and it is hot as hell, If I may suggest; custom wire the lamp so you can keep the ballast outside of room...do you have attic space above your room?

Yeah but its a shared attic, so growing in there is outta the question.

I was talking about setting just your ballast there to reduce
radiant heat in room

How much heat will be removed by putting the ballast in another room?

if you got 6 in there with room for another 2 i would leave the 6 in that seems like enuff room to me
cheers hope this helps swizzy m8

Alot depends on the size of the plant.

I had 30 two foot mothers under a 400 watt hanging straight down with a parobolic hood and it was fine. If you track a 600 watt and rotate your plants you can cover a 5 foot by 7 foot area no problem.
