Spring is near and you might be itching to get your garden started. But there is still danger of frosts and it's better to start seedlings indoors. Light boxes can be real energy suckers, but not if you use LEDs! CheapVegetableGardener.com has great instructions on how to put together a seedling starter box using LED Christmas lights for less than $5 and in just 15 minutes.
Not only is the grow box thrifty in construction, but also in wattage. The Cheap Vegetable Gardener states: "By replacing the two 24 watt CFL and one 80 watt incandescent bulb with a few hundred LEDs I could drop at least 124 watts with my new configuration. Assuming I am running my grow box every day for 14 hours a day this could save me over $45 a year as well as just being the more environmentally conscious thing to do."
