Hmmm...lots of stuff. My plants are way behind many of yours. I have 90% of them in 2.5" square x 3.75" deep containers. I just got to the point where potting up is too much work for the payoff. With my rarer ones, I do it though. My electric bill jumped $40 in a month. It was a multitude of factors (more energy, delivery cost increased 18%, actual cost up 6%, more days to the cycle, etc.).
Tons of stuff under lights...peppers, asian greens, lettuce, flowers, broccoli, swiss chard, and more. I'll be starting tomatoes this weekend. Basil on 4/15. Cukes, Squash, and other stuff on 5/1.
I picked up a few Flowerhouse Starterhouse greenhouses (basically 8' long x 4' wide x 3' high cold frames made of plastic) for a steal price last weekend. I got 3 of them on Craigslist. They're not real greenhouses, but perfect as they are easily put up, easily taken down and really help with the hardening off process. They save me money on lighting really.
Lots of watering, foliar spraying, and just observing. I still have seedlings in the germination tray. Fun stuff. I plan on dropping a few more pepper seeds in dirt if things go as planned. I can't resist a couple.
