j dogg, I read somewhere on here that a guy sprouted seeds with a 1000... he said the light was 5 feet away.. 3 feet seems to close to me.. your biggest concern should be that the 1000 watter will dry out your soil and kill your seedlings.. keep a close EYE... be obsessive..keep the soil moist around the tap root(sprout). A light like that can dry out a seedling in minutes..

word!
