18 plants per person is absolutely hilarious. I completely support anybody growing as much as they individually want at home, is just a plant and its not gonna poison anyone.
1 plant of the right strain, with a level of skill in growing, yields 1-2 pounds. It’s a seventy day grow/harvest cycle. 6 plants with a yield potential of 12 lbs. every seventy days for one person.
not discriminating against habits, and I use a lot of cannabis myself, but I couldn’t use 12 pounds by myself within two months if I used it like potpourri.
