Kids can grow more than 20 kinds of wildflowers with the Light Cube Super LED Mini-Meadow kit. Flowers begin sprouting in just under a week and will bloom in the first month. The kit comes with a plant cube terrarium, an LED light unit, a six-inch USB cable, a wildflower mix seed pack, a germination disk, and instructions.
Follow the instructions to plant the flower seeds and place the LED light unit on top of the terrarium. Plug the light unit into a computer's USB port to turn it on. There are three light settings to use. First, use blue lights to foster foliage. After the seedlings have germinated, use red light to promote flowering. After one month, use both red and blue lights to intensify the growth of the plants. Kids can experiment with different light intensities and times. Kids can choose how long they'd like the lights to stay on by using the LED light unit's timer. (However, it's recommended that the lights stay on for 20 hours in the beginning, and the highest timer setting is only 12 hours.)
Because this plant kit uses LED light instead of sunlight to help the flowers grow, we had high hopes that we'd have success with this kit. Unfortunately, that was not the case. We grew our flowers for a month, carefully following all the directions, and the first few weeks were good. But the flowers never bloomed, and then, eventually, the plants died, which is disappointing.
The Light Cube Super LED Mini-Meadow is for ages 4 and up. Younger kids are going to need parental help reading the instructions and getting everything set up.
When you set this up, make sure you're doing so in an area where it's okay to get messy. The germination disk is round, but the terrarium base is rectangular, so the two don't really fit that well together, which is frustrating. Once you add water, it gets a little messy. We recommend adding the water in stages because adding two cups of water at once has the potential to cause an overflow.
The LED light unit has a two-year warranty from the date of purchase.
A Light Cube Super LED Cactus Garden is also available.
