Okay. So, you can get in a grow at that level. No, its far from optimal. 20-25c is a much more desirable level.
If you have a tent. I guess you're using an exhaust.
So, I suggest you put your exhaust on a timer, only to vent every 5mins out of every 30m r so. This will keep your temp up. If you're not using an exhaust. You can turn your light up to 100% for heat and keep fans away from lights/driver and you'll not any have issues with temp.. for lights off. I suggest they go off at the warmer part of their day in your garage. Tweaking things like this is really easy. And will solve any small issue with big consequences if not done.

I’m using a grow tent without exhaust. I have a fan that is just blowing underneath the 130w led light. Changes the light plan to be 100% of the time. There are 2 roasters on the lower part of the tent for some fresh air top is closed the keep the heat in
I do have a little BlueBerry OG growing in the same tent, this is NOT a Autoflower would it be fine to give it the 100% light as well?

J'ai aussi se problème. Alors j'ai isolé ma tente. Puis l'été je pompe de l'air à l'extérieure, ca chauffe trop même avec des LED. Et l'hiver je met un échangeur de chaleur, fait maison, sur le circuit.

65f is what id consider safe. End flower i drop to 67. Under 65 you risk phosphorus deficiency, then the phosphorus deficiency will lead to other deficiency. Also you will have slower growth at cooler temps. However in my aeroponics greenhouse I have hit temps at night under 50 in the spring without issue. But the temperature was brief

Snapped stem autoflower 2nd week vegHey guys, today I accidentally snapped the main stem on one of my plants. Unfortunately, it was snapped off completely. I've managed to fix it back with tape, but it's holding only on small part. What do you think ? (Notice the steam under the tape)
