Week 8 started!
And here is my double decker had worked last two days to rebuild my box.
Test run with low fan speed.
Enjoy

Hello Intruder, I had been absent for along time. The best setup starts from the best light spectrum, look at the light spectrum of the hps near you first. Then look at the power.
I have picked gavita 600w cause they have build in reflector, my second choice would be OSRAM gro lux 400w, as their spectrum is very good!. But you also should look at this thread http://boards.cannabis.com/growroom-...lbs-light.html
