Hey y'all, looking for a cheap led light that will let me start my plants indoors, doesn't need to be anything big since they'll be there for a week or 2 max, after which they will be transferred outside. been looking at these led lamps that give me either 18 or 45 watts, full spectrum of light, timer and all that, question is, will that be enough? or should I look into something more powerful? cheers
