So mountainman,

You now that know you will need at least another six to eight weeks of flowering before harvest. There are a few other thing to consider. Potency will be determine by the genes you have selected to grow nothing can increase or decrease this item. What you should be considering is how to maximize the yield at your harvest date with that 400 watts. How you ask? Well, there are factors that you as the grower can address or ignore. They include pot size, available fresh air, amount of fertilizer and the amount of additional CO2 added. I will now leave you to ponder each of these issues on your own. Each one of them make up a small part of the overall picture yet each one equally important in maximizing the yield. Happy growing.
