If you have indoor plants, these are a must have. The built-in timer function is really nice so i can set it before leaving for my day. The 10 brightness levels lets me pick the right one depending on how close they are to the plant.
The clamp is quite strong and there are multiple settings that are easy to use, so those are the good parts. The other pros are that it is affordable.
This light stand and grow light is a marvel of simple, no-fuss design. The flexibility to raise (and lower) the light as the plants grow is a touch of genius.
