Out of all the grow lights,this is definitely the bestest!!

What a high-quality light! I am impressed with its fit and finish. I just received it a few minutes ago. I haven't purchased anything of this quality in a long time. I will write more after I get my herbs under it. God bless America!!!!!

This is an easy to set up, full spectrum grow light. The best part is supporting small USA business that have awesome products. This grow light will outdo any cheap Chinese grow light found on Amazon.

Very high quality grow light! I've used them for seed starting and for growing micro-dwarf tomatoes indoors through the winter. I've bought cheaper versions that just don't cut it; I now have a set of these and couldn't be happier.

The set of 3, 33' lights and power supply are very nice and well made. Packaging was secure and the lights arrived in great condition. They work well and put out minimal heat. The personal thank you note from the company was a nice touch too.

I’m very happy with your lights. They were easy to set up and are working great.

Great light, our second. Enjoying salads year tound. Great service light came quick

Easy to set up, seems to work well
