Dabkinganswered grow question 8 months ago If you would like to know if your 100 true watt LED light is sufficient enough for 4 plants, yes it is. However, there are many, many other factors. Tent size, which type of plants, is it photo, f1, auto? Is it a tall sativa that will grow 4-5 ft tall or a stubby Indica that won't hit past 14 inches. Are you doing any type of training? lst, scrog, sog, ect?
But to answer it very shorty, yes it is sufficient. When you increase your lights, you will in turn get a bigger yield. This is why outdoor plants ALWAYS will be bigger than indoor because NOTHING is on par with the energy the sun puts out.
