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.
