This indoor herb garden germination kit is designed with a water circulation system to increase the oxygen in the water. Plants grow faster in nutrient water than in soil. The height of the lighting part of the hydroponic growth system can be adjusted according to plants in different growth stages, so as to help plants absorb energy from LED lights and promote growth. It is an educational gift for children to help them observe the growth process of plants. Parents and grandparents will also like fresh vegetables all year round.
