Looking for greenhouse cold weather advice or experience

[becauseofseizers]

For the people growing or finishing in northern climates. Like 43 and up.

What temps can you get down to?

What do you do to keep warm?

What temp will spell disasters?

When do you finish?

Thanks

What temps can you get down to?

Below 15°C the plant stops metabolizing and growth stops.

What do you do to keep warm?

You can put a heater in the greenhouse.

What temp will spell disasters?

Below 5°C is cutting it short...

When do you finish?

Before humidity turns your hard work into one mushy fungus. Check trichomes and if they look ready take down. Keep a fan on or over the plants to keep air moving and try to aerate your greenhouse as much as you can.

I guess these are not the awnsers I am.looking for. I want more specifics on green house operation into fall. Not general cannabis harvesting info.

Are you talking greenhouse automation? Because growing in a greenhouse is not that different from growing in a tent. The main difference is that light en temperature are a bit harder to control. Not to say that this impossible, but it comes with a cost that would probably scare you away to indoors in a tent...
Unless you grow for a living I would say take the free light and warmth you get from growing in a greenhouse with open arms and take the fact that in mid summer you can get temperatures well above 40°C and in winter it will freeze during the night.

Hey, wont have answers to all of your questions but i grow a small autoflower plant and the temps have gotten down to 8°C usually its at like 12° during the night the plant still grows bigger, im harvesting this friday. At first i tried to close the greenhouse doors and windows as much as possible during the night but if i ever slept in that would probably mean mold because during the mornings i get 100% humidity. Oh and i also have my pot on a cinder block to keep it from the cold ground, but dont know if its doing good or hurting the plant. I know i didnt provide much info but hope that it helps
