I'm using 1 1000w led light for the whole grow because you guessed it, I'm cheap and i want to experiment for my first closet grow. I'm also not going to be using any nutrients.
I'm using 3 gallon smart pots and Ocean forest mixed with perlite for my medium. That's it!!
The light I'm using is from Amazon; Gliixer 1000W LED Grow light, dual switch.
