The seeds I have planted:
Problem is, I have 4 cats who like to eat and/or generally mess with my plants. All of my houseplants are on one crowded shelf in the cornered-off guest bedroom, except my rosemary (who cares if they eat it, it needs a good trim and it's not bad for them), my bonsai trees (which for some reason, they leave alone), and my lucky bamboo (which has been eaten and barfed too many times to count, and now we're trying rubbing "bitter apple" spray on the leaves). Point is: we are very limited to where we can keep the plants.
Also, I spent about $50 and countless hours running back/forth to home depot, constructing a PVC-pipe structure with fluorescent lights, set on a timer, that fits perfectly on a spare table we had, so I wasn't about to give that up!
Well, last night we set off in search of some back heating pads. Couldn't find A SINGLE ONE at Walgreens that didn't have an auto-shutoff. So, that was out.
Went to Menards and found their seed heating mats were about $25 each. I have 2 trays, and might have a third, so that would be an extra $50 (or even $75), so that was out.
Tried the incandescent bulb thing again, this time with some new shop light clamp fixtures from Menard's, that had metal reflectors on them ($7 each).
HOLY CRAP, THE HEAT!
My temps were measuring above 100 on the tabletop. YIKES! Adjusted the heights of the bulbs to get the right temps, and we are all set to go now.
Thanks for all of your suggestions!
