Thanks to TLF admins for allowing us to respond directly to questions/concerns about our products. We hate to see characterizations of "snake oil" or criticisms of unrealistic claims since our products have been used for over 16 years by governments and the largest industries. exiGrow is one of hundreds of solutions that replace common dangerous products by using a natural acid replacement technology, Syntech, that has the power of 0pH but is completely safe. exiGrow is a superior replacement for common soil acidification solutions such as citric acid, sulfur, or phosphates because of Syntech--any comparable acid would kill plants and be dangerous to the user. The patented Syntech is sophisticated, but the chemical reaction is pretty basic. Since other soil acidification products have a much higher pH, these can take many years to remediate alkaline soil where exiGrow will have an immediate impact. By solubilizing the otherwise insoluble mineral salts that build up in soil, especially in areas with hard water, exiGrow makes the essential nutrients available for plant uptake and makes the soil more porous. Obviously, exiGrow is not for everyone and it isn't a magic potion for all lawn problems--we only promote it in areas of the US with alkaline soil and hard water, and we encourage homeowners to test their soil and include exiGrow as part of their overall turf management program. You can see some soil test results from golf course customers and learn more about Syntech at www.truSpring.com/pages/syntech. We welcome any questions or comments.
