600w HPS kit + 0.4 square meters of space

hi guys , i just wanna start a new grow but today i measured my grow space and is around 0.4 square meters with 1.5 meters high . i also already have 600w hps lamp + cooltube , and i start thinking how many plants is optimum for this space , this big lamp will affect my plants beacause is to much light? with the temperatures i will handle it , (winter is coming , not such a stealth grow)

hi, in such a small space you could only do 1 and if i was you id look up "stadium scrog" perhaps looking at a bulb to hang downwards,, others might have better ideas but 40cm is a tight space, the 600 would proberbly be overkill also heat in such a small space could be a problem, well good luck anyway
cozz

its not 40 cm , i probably expresed wrong , it's something like this :


i want to know if i put 3-4 plants for how long i am need to veg them ? i would like to grow northern lights

Aslong as the light/cooling ( guessing you are seeing as you're doing it in winter at 600 produces a fair heat) your good

3 plants will be okey to germinate?

You should look into a Scrog grow, 2 plants northern lights Scrog should be okay.
600w in that space is too much imo. I had a 600w tube over 2 x 3 ft and it was bleaching the tops, i had to knock it down to 400w...
I'd be inclined to think "F^%k it!" and make the space as big as the light...but I guess you would if you could...

yes i am planning to SCROG and use the technique FIM , but i alreaday have this light and no money to buy a new one , thx sworth

Bigger space then stamate!! If you're still growing in six months it's almost inevitable! lol!
Good luck...
