How much could I expect to harvest??

hey guys im kinda new to growing and i had a question. I have a 400 Watt HPS bulb on 4 great white shark seeds that i bought from greenhouse seed co. 2 fans running with miracle gro soil. All are in 12" pots. How much could i expect off each plant?

what kind of nutes are you using?

id say you can expect 40-60g's/plant.

probably close to an oz. usually thats a round about figure for good genetics plant. keep everything corrct,temp,timers, lights, and nutrients and she will flourish

Have you looked up the strain info on the website? It normally tells you the yield, but thats under perfect conditions. Whatever it says, expect 1/4th and hope for 1/2 of what it says.
