Customer Reviews

GOOD Review by CDS
Good product so far. I've only had it a couple of months. Stand is very light weight and easy to move around. Assembly was very easy. So far, my plants seem to enjoy the light and are thriving. Am looking foward to trying it on new seedlings in a couple of months to get a jump start on my garden.
