I’ve given 4 stars because I haven’t… I’ve given 4 stars because I haven’t had a chance to see how the lights perform on plant growth yet. The 4 stars is for the shipping experience and I did put the light units together to power them up and test them out with the app as well. So far so great, the lights are really super bright and the app work well too. However I would have preferred to have the option of operating the lights without WiFi. Just a basic on/ off switch would have been nice.

Highly Recommend Amazing products, amazing customer service. I recommend Growstar to all friends and family

Still waiting on my return label sent… Still waiting on my return label sent out two emails now and nothing

Great price for a quality light Love being able to control this quality light through the app.

I've had these lights for two years… I've had these lights for two years now. I have two 4x4 tents with 5 groplanner 150 o series lights in each of them . I grow 4 plants in each and my average weight is 8 ounces per plant. My biggest plant came in at 14 ounces that was an indigo express strain. I've compared these to spider farmer and they can't match the par value of the groplanner. Depending on whom you buy the lights from you can get them at a good price. I don't use the wifi since I don't trust wifi so I use digital timers. Groplanner recommends 4 lights but like I said use 5. One in each corner and one in the center. Excellent light penatration. I highly recommend these lights
