Spring light dep grow 20x60

Been vegging for 2 and a half months. I vegged long becuase i do not want to flower them when its too cold. Flowering started since since February 1st. I and using general hydroponics 3 part nurtients. 220 plants in 15 gallons. Will be doing heavy pruning after the stretch.

Plants have been topped 3 times over the course of this grow. In two weeks these ladies will stretch and double in size. I am trying to further dial in this set up. But so far i think this is as good as it gets.
