How to Grow Marijuana
Choosing a space to grow
Containers - Large plastic pots (like the
ones bushes come in) work best.
Lighting - Since there is no sun in your
closet you will have to provide a sun
loving plant like marijuana with a lot of
artificial light.
Temperture - Marijuana can survive
tempertures from 32 degrees F to over
100 degrees F.
Water
Ventilation - If you are running a small
closet operation then just opening the
door twice a day to look at them will
create enough air movement for healthy
growth.
