I'm curious to know how you got a 430 watt light 8 inches from a plant and had no burning.teckS said:about 6-8 inches, personally i had my 430watt 8 inches away from my plants and had absolutely no burning or overheating, but thats just me, keep it a litte farther away, put your hand over the top of the plant with your palm touching the top of the plant, if the back of your hand is comfortable and not too hot, your plant should be ok as well, if the plant is really young, your may want to keep the light farther away especially if they are very young clones.
