I purchased my LEDSTAR AQ-D RGBW after having a full tank of plants for a month without growth using a Hygger light off Amazon. I noticed new growth within a week of swapping my Hygger for the LEDSTAR. I’ve seen bad reviews of the LEDSTAR app so I’m afraid to use it, but I have it on a smart plug schedule. The light looks very nice as well. I’m really pleased with it.
