FROST: general rules from experience....

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)
 
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

this year I chopped mine two days after first frost. got down to 24 with 30-40mph winds, after that they started dying RAPIDLY haha.yeah, when they're in the ground theyre more tough it seems. i just hate having to deal with the anxiety of when its going to freeze over
Have you learned anything in the last 10 years that you might like to expand on if you're still on here. I'm curious I live in northern Canada

the first frost of the year was on sunday night, i checked my pumpkin patch today - tuesday - and everything seemed fine. the temperature dropped to -1*c so it wasn't a hard freeze - the weather network also posted a frost warning. the only difference i found was that top colas were 'browned' and withered a bit but the rest of the plant parts (colas underneath, leaves, stems, roots etc..) seemed intact.

here are two photos of the top cola of one of the plants. the first one is from friday (before the frost) and the next one is from tuesday (2 days after the frost).

hope it helps as i had no idea what to expect as well...


:weed::weed::weed:
I've gotten black on my leaves too haven't gone to frost. Wondering if this is similar to mine looks like it

Man, I'm sorta scared. I have done a lot with my jack herer this year, it's a 10' my maybe 11. Spent a lot of money on the nutrients. It's in a 100gallon pot outside.. im in VA.. does anyone know if jack herer (from experience) is a okay plant in the cold? It hasn't gotten down past 38 at night yet but we're getting closer. My Jack is like a month away still from harvest. I have a burlap I'm putting around the pot tomorrow, plus I've got a plant cover I'm gonna use if it goes past 38. Does anyone with experience have a opinion of what else I can do?
