Herb growing kits are the simplest kits among all. They consist of simple glass bottles, seed packets, cotton wicks, and a plant holder. To grow the herbs, you should fill the glass bottle with water and place the wick inside the bottle. Then connect the wick to the plant holder. You should place the seeds in the plant holder. The wick ensures that the seeds get the moisture that is necessary for germination. To prevent the seeds from drying and to protect it from pests, you will have to cover the bottle with a sticker. After germination, you can remove this sticker to let the plant grow out.
