The GrowLight Kit provides everything needed for children to plant and grow variety of herbs, fruits and vegetables right in the classroom. Utilizing the very latest LED light with wavelength tuner and hydroponic technology, children will learn about variables that control growth of plants including soil types, watering nutrients, CO2 levels, function of roots, as well as see for themselves how different light wavelengths impact plant growth. With the HamiltonBuhl® LED GrowLight™, photosynthesis will no longer be an abstract concept, but will be an observable event as children tune the GrowLight LED lights to the optimal spectrum for the plant they are growing. Our GrowLight tuner is designed to allow tuning to the optimal spectrum for the plant during the plants phases of growth form germination to flowering.
