Customer Reviews
Another solid order
I ordered a PROGROW 640 this time. As usual, it arrived on time, took about 4 days to reach me in California. Packaging was good. This consistency is why I keep coming back.
Good PROGROW 320 for the price
I was looking for a decent full spectrum light and the PROGROW 320 caught my eye. I had a small first order discount which made it a good deal. Shipping was pretty quick, about 5 days to get to my place. The light itself seems well built for what I paid. I was checking out some other brands but the overall value here felt worth it, definitely a practical buy.
