Edmonton, Canada ( VENTING)
The winter of 2006-07 we had several new clients in the Edmonton area using GreenJacket® for the first time, some with Insulation and some without Insulation. As the winter season approached the weather and temperatures leading up to the time to install covers was mild and wet, not the best weather for hardening off the turf and allowing it to go dormant. As a result when uncovering in the spring, some of the greens had experienced what was believed to be "Anoxia" or suffocation death. (for more information on this topic read "What Goes On Under Ice?") We continue to gain an understanding of why this happens, Poor Cold Hardiness levels of the plant and wet soil conditions prior to freezing, plus heavy wet snow accumulation that remains for long periods can lead to anerobic activity that results in Anoxia. This past winter, our client utilized our GreenJacket® Venting System and viewing the results shown here, seems to be the best process at this time for exchanging air under the covers. It allows an exchange of air & gases that may build up to be flushed out by new oxygenated air produced by a back pack leaf blower. The photos show the cover actually being lifted by the fresh air produced by the blowers, allowing it to completely infiltrate under the cover.
