I've only seen trees and one grow that could produce 3lbs on one plant. Here is the thread's link.

Now to produce this weight every month. You'd need to start one plant, via this method, every month, until you finish the first plant. You'd need two rooms as well. One to grow and one to flower.

So, from what I've gathered you need to either plan to have say 12lbs every 4-5 months with one room, OR you can have, or run, multiple rooms. Such as one to grow and one to flower. Giving you a new crop every 55-80ish days.

Depending on strain, lighting, grow technique, nutes,.....

MOST people hope and pray for 1lbs per plant. Many pull it off, but not all.

So, read read read..:thumbsup:
