Since the Sun Blaster Grow Light Bulb has a relatively lower wattage, we recommend positioning the bulb around 6 inches from your thicker succulents and 8-9 inches away from more delicate succulents. To help succulents grow plump and juicy and have better color, we recommend giving your plants at least 6 hours of daylight per day. So if you live in a place where the sun isn’t out much, a full-spectrum horticultural lighting system will help you provide that light. Just make sure to be use it in a safe place away from water and kiddos!
