I have 11 plants out this year. They've grown quite nicely and have been flowering for about 7-8 weeks. I live in canada, toronto ontario ish. The temperature has dropped significantly in the past few days from about 15 degrees celcius to 0-4 degrees celcius and i am not sure whether to harvest or when to harvest. Can anyone tell me what I should do. I do not want these to die haha this is my down payment for a house this year. Thanks

did you start flushing with water?

yep i have

Pics would help , but if temps are that low you don't have much choice , are they in pots or in the ground ?. Can you cover them with plastic sheeting ?.

I thought the U.K was bad for weather , its been quite mild here but for never ending cloud cover.

dmcefc is right, all you need to do is make a tee pee with sticks make a hole put them in and then tie the top. Then I use painters plastic it is comes is large rolles but any clear plastic works. I have used clear trash bags also. don't forget to take it off tho. The plant needs to breath and mold can build up. Shake any water off plant.
