Thank you hoppy. Would that be the same even with the stock bulbs that I listed? Or if i got 2 new 39w 6500K bulbs?

Reason being is my growth is significantly slower with the stock bulbs than before when i used 2 flat coral life fixtures with very poor reflectors.

Although it was still 4 bulbs. and they were 6500k each, not HO
