2 plants per 1000w

I recently did 4 plants in my screen under 1000w. It filled up pretty fast and made me think it would be easy to cut that number in half.

I have been think of using 10 or 15 gallon smart pots for each plant for fast growth and maximum space.

Anyone have any insight?

How well did those 4 produce? Do you think you had enough light? Either way you can add more light or cut the # of plants. I would add another 600-1000W and compare.
