Under the Witch’s Hat

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 its roots.

Slowing down water delivery greatly benefits both the plant and the grower.   We can save water, preserve soil nutrients but most importantly we can foster health and rapid growth.

Modern drip irrigation, in either the form of permanent infrastructure, or in simple devices designed for individual plants greatly slows down water delivery but it still delivers much too fast.   Furthermore, as drip irrigation relies on passing water through an orifice or a small passage, or in some cases through a water-permeable medium they are extremely sensitive to clogging from impurities in the water.

In contrast, 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 that enters the Water-Witch™ through the straw displaces the exact same volume of water, released at the rim. As it is metering air rather than water, the Water-Witch™ is very insensitive to water cleanliness.  

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 and predictable periods without attention
• Non-clogging, even at extremely slow emission and even with dirty water
• Adjustable, constant emission rate, even as the water level diminishes
• Rapid vegetative growth
