This project uses dehumidifying crystals and an optional use of a greenhouse to retain water within houseplants. It will work best for indoor plants that do not like very moist soil, and in damp rooms. It is ideal for herbs, geraniums, etc
Although it provides the plant with water, occasional watering may be needed.
This project can be used by 'forgetful' people who usually kill indoor plants by not watering them.
I have used it whilst away on holiday to both keep the plants alive and to reduce dampness in a empty house - a win, win project!
