The timer function works great, it's really bright and puts off the perfect amount of heat. The light is just a tiny bit brighter when plugged in. I have mine set for 6 hours and use the blue and violet lights.
This planter is well worth the money. It usually takes radishes a full month to harvest outside. This is the cutest little aerogarden seed pod sized life support carrier.
Works great for starting seeds from peat pellets. I have this set up over succulents.
It is compact, with a dimmable light and timer. The height is adjustable for different size pots.
My favorite part is probably the timer function. This allows me to tailor the settings to how my plant likes it. The only downside is that it seems to be coming on later and later.
The timer is an incredible hassle to get it to work. The controller does nothing and the light just flashes a bit.
