It all starts with natural and organic peat. We harvest the peat dry it at high temperatures to sanitize it and then press it into our biodegradable Jiffy-Strips?. You?ll love how easy it is to transplant the pot and all! Jiffy? peat moss is responsibly sourced from Canadian peatland and is restored after harvest. When starting the seed indoors keep the strip in one piece. Once ready to plant outdoors saturate the strip and rip it into easy tear cells. The watertight base plastic seed starting tray & clear greenhouse humidity dome are reusable.
