So, if you have have a 200W smartlamp, I would add about 50W of a mix of warm and cold white LED to supplement it. But it would be even cheaper to use fluorescent for this.
They only make Smart Lamps in 300 w and the smartbars are 500w. But yes, it would be way cheaper to use fluorescents for this project. I too would like to see a veg to harvest (or seed to harvest) cycle using these alone. The problem is, who really has money to afford these if they already have HID lighting?
