A: About $2 per month, using the average price of 15 cents per kilowatt hour: $0.15 x 19 watts x 24 hrs/day x 30 days/month / 1000 watts/kilowatt = $2.05
A: Thank you for your question, actually this grow grow light's estimated annual energy cost is $2.29 depends on use for 3 hours per day

A: Thank you for your question, the amount of distance and time used all depends on the type of plant being grown. High Light Plants (such as tomatoes, peppers, perennials, etc) would benefit from 6” distance during the seeding stage, and a distance of 16”-30” during vegetative/flowering stage. Low Light Plants (such as basil, lettuce, etc) would benefit from 12” distance during seeding stage, and a distance of 24”-30” during vegetative/flowering stage
A: I don’t know why this is happening. I’m not having any problems.
A: Thank you for your question. Specs show: umol/J = 1.3 umol/kWh = 4.7 umol/s = 25
