Propagation Mist Kit is a do-it-yourself kit that offers a low cost solution for your propagation, misting needs. The system features the new #549 Mist Timer that attaches directly to your faucet, and will time in seconds. Kit also includes high quality parts like a 200 mesh stainless steel filter to help prevent nozzle clogging. The UV treated tubing, 50' and leak proof compression misting nozzles that will last for years to come. Our unique nozzles will swivel 360° and adjustable to put the spray where you want it to be. The system is easy to assemble with scissors or a knife, no gluing required. The system can attach with either snap clips, cable ties or nail on clamps, all included. The kit is expandable up to 100' with 20 mist nozzles (extra nozzles can be found here on Amazon). The mist nozzles use approximately 3/4 gph at 45 psi, higher pressure will of course increase the flow rate. This is NOT for lower pressure than 45 psi as it will not mist, and nozzles will only dribble. Contains: 50' 5/16" Mist Line, 1-Female Hose End, 7-Inline Adjustable Mist Nozzles, 1-End Line Adjustable Mist Nozzle, 1-200 Mesh Stainless Steel Tee Filter, 8-5/16" Nail On Clamps, 8-Hanging Snap Clips, 8-Cable Ties, 549 Mist Timer. New features on the 549 timer include a solar panel to charge 2-AA rechargeable batteries, but good quality AA batteries may also be used. Rain sensor automatically shuts down the program in the event of rain. Up to 9 programs can be used. You can now program your start and stop times, unlike our 548 model. Of course you can still program this timer to run in seconds for propagation and mist. To see how easy it is to program, Google 549 Mist Timer. You can purchase either the 549 timer, or propagation mist kit separately here on Amazon.
