When we water our plants conventionally we supply the water thousands of times faster than plants can actually absorb it. We saturate the soil, leaving the plant to slowly absorb it through their roots.

Extremely slow, constant supply to match the plant's ability to absorb greatly benefits both the plant and the grower. We can generate the healthiest and fastest rate of growth while saving water and preserving soil nutrients.

Modern drip irrigation greatly slows down water delivery but still delivers too fast.   Furthermore, as all the devices rely on passing water through an orifice or a water-permeable medium, the slower the emission rate the more sensitive they are to clogging.

In comparison the Water-Witch™ uses air rather than water to regulate emission.   Once inverted, a vacuum forms in the bottle under the weight of water, and air is slowly drawn in.  Each bubble of air drawn into the Water-Witch™ displaces the exact same volume of water. As it is metering air rather than water, the Water-Witch™ is very insensitive to water cleanliness and the emission rate remains constant and predictable even as the container empties.

With its patented design, the Water-Witch™ delivers a unique set of benefits:

• Extremely efficient use of water - the plant receives nearly 100% of what is supplied
• Extended periods without attention
• Non-clogging, even at extremely slow emission and even with dirty water
• Adjustable, predictable and constant emission rate
• Rapid vegetative growth

Our Vision

 

Abundant waste single-use PET bottles exist in nearly every country on Earth.   Our long term goal is to use some of this this waste, together with resources generated from sales of the Water-Witch, to help people around the world grow food, plant trees and save large quantities of water.   To learn more about our ambition visit our company website linked below:
