This year I grew approximately 50 plants in containers in my driveway and have been harvesting Habs, Thai's, Cayenne's, Hot Red Cherry's etc. I grew all of these plants from seeds. Since the frost is almost upon us I want to bring the plants inside and continue to grow them in my basement using a high pressure sodium light. I'm going to be growing them in two areas each approximately 10'X10'. The ceiling is 7 ft. Does anyone have any recommendations for the wattage of the sodium lights. I intended to buy two 400 watt lights however the company makes 150, 175, 200 and 250 watt bulbs. I'm concerned because of the small area and I don't want to burn the plants. Any advice would be most appreciated.
