Hell no. NOt even close. You could put a couple 600;s in there or even a 1000 or 2. My grow space is 2'X4'X4' & I run 2 150 watt HPS lights in there with 8 t-8 flouro tubes & I could use more lights.
I tried just using the flouros for a grow. It worked, but the buds were very light & fluffy.
I am a true believer in HPS for flowering.
I would recommend getting a 1000 watt HPS light for that area & be prepared for the massive growth & stench.. Good stench
