And then after all those seeds grow, and you let them veg a long time, why just one plant could supply you with 5 pounds....but that is a big, big plant.

We are kinda joshing you. Those kind of questions are difficult to answer. Not only that, when you have a full time supply, you use will increase.

So, if you grow a little plant you could get an oz off of it, if you grow a big plant you could get pounds. Up to the gardener to decide. Kinda duck soup with chickens and geese.
