Are you flowering yet? If not you can just 24/7 the lights.

Propagation mats under my pots have been a game changer for me during the cold winter months.

have you considered a night lights on cycle with a day lights off cycle to take advantage a possibly more average temp / less temp swing?

Plants do grow at that temperature, i've grown all year round in a UK attic without heaters or dehumidifier, I always got a return I was happy with, I can't remember the exact figures but below 10c in winter during lights out.

Now I wouldn't waste my time without the right gear but fs we all started somewhere, my 1st grow was a light and a fan... full stop lol.

Why not just turn your lights on overnight vs the daytime? In the winter it's the best way to avoid the overnight chill

In my opinion temperatures in the 20's and 30's can kill your plant but anything 40+ your plant can survive it might not like it but it will survive im talking Fahrenheit
