Seedlings need less light move light up to 3ft above the seedlings. Then in about 2-3 weeks when each seedling has 3-4 internodes (sets of leaves) you can move it closer. back to the 20 inches If your light has a glass shield you can have the light 18" above tops with suffcient air flow good luck. ** the temp can come down to or try to get it down to 25 cel. about 75 degrees Farenheit. also keep soil moist, I use a hand sprayer or mist bottle and keep soil surface moist.**
