Interesting questions and realised yesterday I am getting below the low mark! Yikes. I have grown every year for the past few decades for self reliance. For several years during 2002-2006 I had a deal with my housemate of a max of 8 plants in our small garden, 4 neigbours peering right in. But lots of years that were not successful.
Lately with more space I grow for my own use and my partners. I am not to sure what that amount is, but its alot. I really have never counted, how many grows. We grow throughout the season and always have a plant or two even in the winter months. Pick here and there, dry, cure and smoke.
Last season we flowered about 30 fairly nice sized females during our summer grow season. Each plant was atleast between 200 -500 grams of decent bud.
One way I like preserving seasons weed is by making bubble hash. You can use the trim and popcorn buds to make different grades of hash which can be stored in small spaces for long times.
We also use the decent trim and sometimes flower for making edibles during the course of the year.
