How many plants you putting in that 32 sq ft?

The 3 oz to the plant does not sound to bad. Were the plants seed plants or clones? How long did you veg them, and how long were they in flower?

It just seems to me that your lamps totaling 864 watts is not quite enough, or do you have some empty space in the room?

I have used the T5 HO for almost 4 years growing. I was pretty impressed with it, but as of late I have been steering back towards the T8's. I think maybe this next run will be a combination of the two.

I recently discovered a new fluoro type of a fixture that I think might be even better than any type I have seen. It is called an induction lamp. It is a gas fired tube and the temps are low with the approx. lumens of HID.

I was told about a ballast called an ice blue 660 i think. It can be used for T12,T10,T8,T5 HO and VHO. Some how it is supposed to over drive the HO 54 watt and put out 84. I would sure like to learn more about that ballast and maybe if anyone else produces such a ballast as the ice blue one was a pricey ballast.
