for frost protection you guys should really look into electro culture. its gotten some crazy research on it about you build this tower and it generate a electric field that will keep the plants in a general area protected from the frost.

Nights are dropping down to 50F here (Zone 11). I am running Amnesia Autos and they don't seem to mind the cold.

I am amazed some of you guys are growing in freezing temps, I didn't know that was possible.

They won't grow. The sap becomes thick when cold. They will tolerate the cold(depending on the strain and how healthy) and continue to grow when the temp rises again and warms the sap. I live in Michigan and frost is by far the number one issue(aphids, gnats and mites.. and piece of shit thieves are a close second)

this sounds futuristic to me. Very cool! Zone 4 and figs and citrus have to come inside for winter.
 
I’ve got a question, I’m a rookie at growing I have a Goji runs growing in a gallon pot with 2 other gdp plants on the way. They are currently outside and the temp gets to about 40 at night. Recently I’ve been asked to move the small sprouts out of the original growing pot. My question is would black garbage bags be good enough to start a small grow room about 6”ft tall 5”ft wide. And I was thinking about lining the inner side of the “room”with tinfoil, would it work? And what works better uv black light or regular sun lamp ?

I've had cannabis plants survive outdoors for an entire winter in an unheated greenhouse that gets below freezing at times.
Most the post hear seem to be coming from northern growers who face frost at the end of their bloom. Dose anyone have experience with frost in the early flower cycle? I would like to try a spring harvest in 2024 and would like to start the bloom as early as possible. Weather reports are decent about 2 weeks out qnd I can monitor for the best start time but how much resistancey will they have at week 3 or 4 of flower?

it may have been mentioned earlier in the thread, but if you get that white insect protection mesh, the very fine one, its quite good to drape over your plants in pots for that extra protection.
plants in the ground will obviously do better, but i make a sort of bag to go over the top of the plants and put the pots into larger pots with clay balls all around them, makes for good protection/insulation
