Autos are likely fine with overnight at 6C but any lower and you should have them in a greenhouse or inside. Keeping the root zone comfortable is more important than the air temp so you can use a soil warming cable to make a warming table, or use a hoop greenhouse. Or just bring them inside the house on the rare cold nights. Good luck.

10c air temp and more importantly the soil temperature will slow the plant down. Not a big deal with photos that can just go until ready. Auto's though are another story. They are on a fixed schedule so anything that is not optimal will affect yield.

Anything below 10°C will cause issues and 10°C isn't very good either.

anywhere between 2c to 15c will probably cause stress and slow them down. It wont kill them but yeah its not good best temps are in the 20s anywhere between 22c-30c is good for optimal growth.

What is happeningWhat is happening? Northern light was to cramped but could not move it so the photoperiod plant dominated it. I just put it under a led 60 spot light. This does not look at all like my other Northern light. Thanks in advance and will it give me anything.

Seedling in TroubleI have a seedling that is alive but has not popped its cotelydon leaves open yet. It almost looks like part of the seed might be stuck and holding it back.
As it stands now, I'm thinking I should just leave it alone and give it a chance to finish the job.
Recommendations?

F my main stem broke ALMOST totally. Will she make it?On advise I was removing the wires off the fan leaves, but then the main stem broke ALMOST totally at a very low point, about 2 cm above the soil. I taped the wound and put her in a position where the wound is closed, so the LST is ruined anyway, but will my little girl be okay?

How to tell when buds are dry and it's time to start curing?When drying how do you tell when it's time to start curing, ik from what I've read says the stem needs to snap, the outside of some of the buds feel dry but the stem isn't snapping it bends like it is almost going to snap. Is it safe to start curing? Been drying for 4-5 day's.
