400 or 600watt for a 2x4?

[rolljoeroll]

Which light would be a better choice im worried the 600 might be overkill. Also what hood should I get?

What light?
HPS?

If you can keep temps under control 600W Other wise 400W will do fine.

i'm currently running almost the dame size cabinet,the 400 will rock it just fine .
i would be worried about the heat with a 600 in that size i run a 6 inch can fan with cool tube and if it gets above 75 outside temp the room temp shoots up drastically,

I'd personally do a 600 with a dimmable balast. that way if you can handle the heat from the 600 then run it. if not bump it down to 450 watts.

I agree, can't go wrong this way!

i'd run some LEDs in that space, that's a bit too tight for a 600w hps in my opinion and a 400w hps is best for a 3x3 so you would be missing about a foot of coverage, check out these , kinda pricey but if you can afford they would be the best available option in the market in my opinion, less heat and more light

CFLs would work nicely too

or a 4 foot t5 would probably be perfect

If you look through some of my posts you can see what my 315lec did in a 4'x2' Gorilla Tent. First run with this light and I loved it. I will never go back to hps. Heat was lower, electric bill lower. 190cfm hurricane fan with a 4"x16" mountain air with a 190cfm hurricane as intake to keep the tent inflated. Both fans were on variacs.

I am a "ok" grower. I enjoy it, I am not pro but my 315lec yielded 12oz bud 2.5 oz of "larf"

I had issues with thrips and hermies and a fuck u that made me harvest one sativa 2 weeks early.

My previous grow was a basement with 3 1000hps in flower.

I used the 315 lec the whole cycle except seedlings where i used t5 2'x2'

just my .02
