What are the effects of frosty nights and hot sunny days?

My plants are about 2 weeks away from harvest but we are having a mild frost at night approx 25 degrees at night and 65 degrees for the day,

Put a trash bag over the plant and wrap it or bring it in out the cold .

If your temps stay under 68 for the next two weeks it will damage the plants. As far as I know, constant temps under 68 reduce thc production

Might want someone else to confirm that but.

They are to big for that, and they are in the ground outside.
Should I take my losses and harvest?

Iit will your crop will fail…do what @Yoshi saidMost outdoor varieties can endure temperatures as low as 50F (10C) without any problem. That being said, fifty degrees is still not an ideal temperature because it tends to slow down tissue growth and photosynthesis later in the day. Anything below 40F (4C) can result in damage to the tissue. Gas patio heaters can keep gardens warm on frigid nights. Maintaining a temperature of 60 degrees will promote plant growth substantially.

These outdoor plants can also benefit from a polyethylene plastic covering that keeps things nice and toasty while also protecting the garden from the elements. Heaters can increase protection even more. Download my free marijuana grow bible for more information about growing marijuana.
