I have an indoor Arboretum. 14' long X 7' wide and 21' high.
I am using 6500K, T-5- four foot tubes (6) and I did not see any increase in Electric bill. Lights are on 3 hours in morning and 3 hours in the evening. God provides any additional lighting. I Bought the lights on 1000 bulbs at $20+ each. I did not want the higher electric bill and did not want the additional heat.
Banana plants are putting out new leaves every 7 - 10 days.
I just started to fertilize them.
