My bloom room is 6'x7' - with the plants lined up down the 7' wall 4 deep with 1/3 of the room left for walking water, etc.

If i bought a 6' motorized track would i get enough lumens per plant to do 21 plants?

According to Filthy Fletch i should use 2 cub meters per plant - since im using 3 gal instead of 5 is it fair to say 1 cub meter per plant - if so thats 14 plants, roughly, for my area.

If i put my 1,000 watt light on a 6 foot track can i effectively grow 14 plants producing, as fleth said, 7 ounces per plant? I got 7 ounces out of 21 plants last time and its not worth the electricity bill to do that.
