Had an idea for you
@Carmen Ray.
When I was in high school -- long, long ago! -- we'd save the seeds from that 1 oz bag they called a lid, weed imported from Mexico. This was not your sinsemilla, and I didn't even know what that was. It was bag weed,
consemilla.
So anyway, my older brother and I used a 40 watt light bulb strung through a hole in the top of a fairly small box, it was maybe 1 foot square around and 18 inches tall. Because the box could be closed, the heat the light bulb produced could accumulate. Germination was a breeze in this box. Whether it's paper towels or soil in small pots, it's moisture plus the right temperature (25C/79F) that makes germination happen, not light. Light really becomes important only after the bean has popped and the cotyledons have opened.
If germination at your room temperature is too slow, you might improvise such a box. It would give you the warmth you need in a very small space so heating it will cost very little. After sprouting, the seedlings will enjoy the warmth and light for a week or so. At some point you can easily transplant to your perlite or soil and put them under your grow lamps. Just a thought.
