How to squeeze multiple harvests per year out of a greenhouse

[Mate Dave]

Depends how big your growing them. Flower time make a difference too.. Trees will need veg time which looses you crops.

You could alway grow 8-10 week stuff alongside the 14 week + sativa. Light deprived indica will get 3 harvests in the same time the sats grow out naturally and get really big, you can then plant out all indica for a 5th.

Keeping them short will enable you to use shade cloth draped over the support bars.

Some glass structures have screens, polly tunnels have winches that cover entire tunnels in shade cloth.

Hi Folks, Thought I would give this thread a bump :tip hat:
I'm thinking about multiple harvest in a little different way...

I'll be growing for the first time in March. I am growing Autoflowers (not sure what strains yet). I live in SoCal and am thinking about beginning the grow in greenhouse from seed and moving plants inside shortly after they begin to flower. Greenhouse is 12x14, using coco substrate with auto feeding, and using LED indoors. As the first plants are moved inside, I'll start new batch in greenhouse. Am I right in thinking that about the time the indoor girls are flowering -- the plants outside will be ready to come inside (4-5 weeks outside and 4-5 weeks inside)? My thought is that with our long California growing season, I could produce as many as 5 or 6 crops from March-November.
Being a newby, my main concern unique to this process is how/whether the plants would adjust coming from outdoors to indoors?? Has this been done before? I came up with this plan based on grow my grow spaces. Am I HIGH or foolish thinking I can pull this off? Any thoughts, perceptions, or advice would be appreciated.
Thanks Much!!!
