Fellow Growers,
please help me decide to buy my next ballast.
So I'm going to upgrade from a 250w HPS grow closet to a 1m x 1m (40x40x72) darkroom tent... should i go with a 400w or 600w ballast?
I was hoping I could run a 600w to get them buds real fat!
i got an aircooled hood and 360m3/hr exhaust.
But u can never know, the temps can rise quick.
Thats why I was thinking of getting the 600w Dimmable Ballast by Lumatek.
What I dont know is:
1. What would happen to the bulb and ballast if I had to run the grow with 400w for a long periods of time due to heat problems?
2. Can somebody confirm if the grow shop dude is right... he said if I would use a 600w bulb then dim to 400w for a long period of time, the effectiveness won't be the same as if i would use a 400w bulb instead?
3. OK so if I was to use a 400w bulb on a dimmed 600w Ballast.... how does that compare to the performance of a 400w bulb on a 400w Ballast???
