Using grow lights 100% of the time? No, that's definitely not going to work, unless major gains in efficiency are made. But using led grow lights to supplement passive solar and elongate the grow cycle is what I'm referring to, and designing low-rise greenhouses to capture the sun's energy for the light hours. If you capture excess solar energy, store it, and use it at night, then the energy pull from the grid for night-time grow lights is reduced, and then it's an economic question of cost of energy versus sale potential. I'm not specifically thinking about staple crops (ie, wheat, rice, etc), but supplementary crops like tomatos, lettuce, cucumbers, etc. Mostly, what Thanet Earth is growing.
