1. It's an impressive effort. Congratulations on your results.

2. Where do you get your pots? The dark color obviously works for you, but I worry about the pot temperatures facing west in the summer afternoons.

3. Check my math: You have 2000 watts of lights running maybe 12 hours a day for 3 months, which is 4380 kWh, which is not quite half of what the average house in Pennsylvania uses annually. The average rate in Philadelphia is perhaps 18 cents/kWh, which is $788.

About 50% of this gets converted to heat, so it does lower your natural gas use. The 50% going to heat is 2190 kWh or about 75 therms of energy. At $1.40/therm that's about $105 in natural gas savings if it's 100% useful heat, but some is absorbed and lost by the basement walls, so the net cost is probably $700.
