Outdoor crop ruining before my eyes??

This is my first crop outdoors, and its been getting into the low 40s in the nights now. They're already flowering and have another week or 2 to go. Should I pull them now, and harvest? Or let them go? The hairs are just turning a reddish brown... Not all of them but some. I've never had this problem indoors, but mother nature is shitting on my head now? Are they safe out there, or should I harvest? If I leave them out for the last 2 weeks... Would putting a blanket over them help any to keep the frost away?? I'm about to go to bed shortly so please let me know ASAP! Thanks!

Yer fine just watch for low 30s cover then with light sheet all will be well

Thank you very much!!!!

I posted the same question a couple days ago and everyone said its ok until it gets down to low 30's. I think last night was the coldest, mid 50's for lows coming up. We should be ok. A few people told me the cold would maybe push them to finish a little quicker. Good luck!

This is the crunch time so really keep your eyes peeled for pests and mold if that's a problem where you live.

Ablanket is a bit much ,make a canopy with shade cloth. Sorry i didnt get on before you went to bed.

Couple things about frost. First, 40 is nowhere near freaking out time. Ganja can handle numerous light frosts with no ill effect, as long as temps are climbing back above 55 during the day. Second, IF you're within a mile or so of a large body of water you're looking at even lower temps before frost/hard freeze, even a good size river will have this effect. Of all the plants out there, your average weed plant is VERY capable of handling adversity from a weather standpoint, really hail and extreme winds are the biggest threat. Now for some reason if you're growing outside in a large pot, the variables change a little as roots seem to love being nestled deep underground as cooler weather approaches. Bottom line? There is a reason those tall straggly ditchweed plants are still green after most of the other foliage is a nice golden brown and most of the trees have lost their leaves. Happy harvesting!

Dankenfest, thanks.
How do you tell that a container plant is being stressed by cold roots?

My container plant is quickly losing fan leaves, they are drying and shriveling up.
I have had a serious Leaf Spot infection for months now, so I attributed it to that.

It's not so much cold stress as just risk of freeze goes up. A plant can survive a really hard frost around 28 degrees if the roots are protected under ground where a permafrost freeze takes well into the low 20's upper teens and the buds are covered with plastic bags, but a bucket full of soil will get down to air temp overnight which if it's 28 will just kill the whole plant. What have you been treating the leaf spot with . I've been dealing with some of that on my plants too, been spraying the whole plant down with an organic pesticide that kills loads of bugs including spider mites and is totally benign, you can spray it on fruits and vegetables up to and including day of harvest so it's safe to use on bud, just found it at Menards in the garden section in a green spray bottle but I can't remember the name of it too high right now lol.

Im just going to point out all my seedlings around a week old outdoors got covered in 2" of snow. 2 days later when snow melted they were a ok.

Its impossible to kill mj unless you chop it at base

As long as you dont have constant freezing temps( more than 2-4 hrs), and it warms up into the 50'sF youll be ok. I had a little (16" tall bagseed sativa) that actually got covered in ice twice and she was fine-purple as all hell,but fine. Bigger plants can deal with it better.I don't know your setup but placing large rocks in the sun than stacking around your plant can create a small warmer micro climate, also jugs full of warm/hot water do the same thing. Bury the pot/roots, cover with a sheet if you know heavy frost is coming.

I've even heard of people running a sprinkler on thier plants during extended freezing periods, allowing the plant to get covered in ice because the ice actually insulates the plant from colder temperatures.

Made it through two hard frosts already and girls are looking great, bring on the next ones, im ready for it!

I appreciate all of the advice everyone has given me... This was my first outdoor grow, and they're in the ground not a pot. They're big though the largest being at about 12 feet. I checked them yesterday and still looking amazing!!!

I really like that rock idea. You could even heat them up in the oven to make them last a bit longer. Brilliant .
