Customer Reviews
Consistent quality for repeat buyer
This was my third purchase from Grow Light Science. I bought another PROGROW 1800 to expand my setup. Just like my previous orders, the process was smooth from start to finish. The light arrived in about a week, well-packed as always. It's good to see the consistency in their product quality and delivery. I appreciate knowing what to expect every time I order. That reliability is why I keep coming back, especially since their lights integrate well with my existing master controller.
Detailed thoughts on the PROGROW 2400
I ordered the PROGROW 2400 a few weeks ago for my grow tent. The ordering process on the website was straightforward, and I received an order confirmation email promptly. Shipping took 5 days to reach Denver, which was reasonable. The light arrived well-packaged with no damage. Installation was simple using the included hangers; it came with a power cord, which was good. The build quality feels very robust. I also got some dimming daisy chain cables, which worked perfectly for connecting multiple units. So far, the light has performed consistently, and my plants are responding well. I haven't needed customer support, so I can't comment on that, but the product itself is solid.
Happy with my new light
I was looking for a new light for my plants and decided to try Grow Light Science. I got the PROGROW 640. It shipped fast, arrived in good shape, and really seems to be doing the trick for my plants. Pretty happy with it overall.
Good light, fast shipping
I bought a PROGROW 320. It arrived quickly and works as expected. Setup was easy. I will consider another one for my next project.
Solid value on the PROGROW 4800 HB
I had been eyeing the PROGROW 4800 HB for a while. I finally pulled the trigger during a spring planting season sale. The discount was pretty good, maybe 10% off the usual price. It felt like a solid investment for the money. The light itself is really bright and well-built. I'm always looking for ways to save, and this purchase felt like I got a good deal without sacrificing quality.

Thinking of grabbing a PROGROW 640. How long does shipping usually take to California? Don't wanna wait forever.
Anyone know if these lights are really full spectrum? Or is it like some brands that just say it?
