Well first a 600 will light an area arounf 3' x 3'. The next question is how many plants are you going to try to shove under the light. To get 50" plants i dont think you could fit more than about 4 plants under the light. This gives each plant about 18" x 18" of space.

Assuming you get .5 gram per watt that gives about 300g divided by 4 plants is about 75 grams per plant which is just over 2.5oz per plant.

Usually they will at least double in size when you take them out of veg. This is called the stretch. I think vegging till 22 inches is going to give you nearly 50 inch plants unless you start bending and tying them down.

srry thats a little ot your cool with what yer doin

stop feeding grow nutes a week b4 12\12 is what he is sayin and im just sayin that a mh will have a similar effect but your not gonna stop the streatch



if yer in veg now you should think about fimming or something to get the canopy even before flowering

ya what we are talking about is most if not all growers vegg with metal halide bulbs and then switch to hps when flowering sorry we were getting to technical for u and u will some day get there as well but right now stick to the basics vegg till there 18 inches under a mh bulb then cut the light back 12/12 and switch to a hps bulb and start adding ur flowering nutes as directed from the manufatuer wait 50 day's then start flushing with striaght water u want ur temps to be at 72-76 degree's i think if u follow this u will do well
