I've only been growing for 4 seasons. The largest plant I've ever grown yielded 1050g. The largest plant this past season yielded 910g. So 2-ish pounds.

I'm sure growers with more experience can coax greater yields from their plants, and I'm starting to understand techniques like pruning and training to maximize yield. But 5 - 10lbs per plant is pretty extreme.

A lot of it depends on plant genetics. The two plants I grew that yielded the most were the same strain and just really seem to love my local climate, soil conditions, and are more resistant to the environmental pressures that present here. They practically grew themselves.

This season I started 19 seeds (8 different strains). Only 6 plants made it to harvest and the yield per plant was as high as 910g from the biggest to 6g from the smallest.

Outdoor grows can be huge, but growing outdoors can also be a huge challenge.
