The good news is ...
You are now growing skillfully enough that you are limitted by your light.
I'm at right at 50W per square foot in flower - but since mine are HPS watts, I imagine my flower area is underpowered.
Still, I'm on track to harvest enough to smoke only homegrown - and that's all I really want right now
Actually, Rado, you're in the gram/watt sweet spot. Yield doesn't rise as fast as wattage. Once you reach 30 w/sqft of HID, you have enough for beautiful plants. Going to 50 only gets you denser buds and more resin. Yield won't rise by 67%.
I ran a 600w hoodless hps in 18sqft and grew some seriously fine plants, including that cured SLH that was in the NOTY contest
