how many plants will a 250whatt hps light manage to grow and what kind of yeild will i get usen it ,, my space is about 3ft wide and 8ft in length and about 12ft high im not sure about other sizes iv painted my walls with matt white does it sound gd enough to grow ?
I use at least 50 watts per square foot. You have more room than you have light so you need to know what strain and how many plants per square foot you want to grow and how you want to grow. I hope this helped.
its when they put a screen over the top of the plants, grow them through vegatating stage untill the screen is packed with plant and then start the flowering.
then only the buds shoot up and get to soak in all the light since all the vegatative leaves are contained beneath the screen.
its probally just best to grow a couple plants and get that part figured out real good first
