4. Have you looked into automatic strains?

I could do three rounds a season outdoors back in Illinois. They are part Ruderalis and bloom by age instead of light cycle. Once seeds pop veg them for 2 weeks and they start showing sex. Like 6 weeks after that they're done. I havent messed with them for awhile but hear the strains have just been getting better and better over the years.
I also grew some in a homemade box for awhile on a stagger crop. Since you can flower at 16/8 you can veg right along with your bloom. Start a few seeds once a week and you will be harvesting a little every week. Very satisfying growing experience.

Here is a grow journal from like 10 years go with the homemade box and staggered autos
