Hey guys I Have just upgraded from my small cupboard grow to a secret jardin DR120 but I can't for the life of me make up my mind on what light to purchase it's between a 400 hps or a 600w hps or maybe a dual core ballast and get both? :S
I would prefer the 600w because of the more lumens and better penetration but the main concern is the temps, I don't want to buy a 400w then realize for a little more i could of got a 600w, I'll be using a parabolic reflector (can't be fu**ed with cool tubes) to try and help with the heat issue but not sure how much this will affect the temps, also I'll be running a 4" carbon filter with 4" inline turbo fan moving 180 m³/h pumping out through the roof and using passive intake since the tent is in a small room of its own with a window cracked.

I know you wont be able to give me a defo answer but any insight would be much appreciated thanks

I don't necessarily agree or disagree with the brand(though it is a great brand), I totally agree with going that route.

Thanks for the replay guys well most of you lol I've managed to borrow a 600w off a mate and I'm running temp tests as i type this so far it's a little hot around 31c so depending how it goes might go for a 400w will know when my reflector turns up, and as far as "dual core" ballasts go that's just what the website called it
