For winter storage of a few plants quite suitable, otherwise not recommended. The lamp had been total, approximately 500-600 hours in operation. At the time I had already twice at Amazon complain, and wait until a new comes, as the energy-saving bulb unfortunately holds a few hundred hours and not as stated 10,000 hours.
Otherwise, my plants respond well to the lamp, the days are getting shorter, and the plants thrive. This year you are I think much better than wintering in recent years (assuming the bulb stops by).
