I'm 4 weeks into my first grow and would like some advice off you veterans :-).
For the first 2 weeks I had my dimmable balast set to 300 watts and since then set at 450 watts. I've just put my light's on a 12 on off cycle so would you recommend upping the wattage to 600 or ?
Thanks :-)
 
Cheers for that ! 4 plants in a 1.2,1.2,2.0 m grow tent.
I've been research via Google and combined with your recommendation just upped it to 600w.
Thanks again.
