When the weather gets warm your polytunnel can soon get to a temperature where your plants overheat and become stressed. An Overhead Spray Irrigation Systems is the ideal solution, not only for watering your plants but also for taking the heat out of the air inside your polytunnel.
At Robinson Polytunnels we supply complete overhead irrigation kits for your polytunnel. We have two ranges suitable for polytunnels 6ft - 10ft wide and 10ft - 16ft wide. The LDPE irrigation pipe is fixed to the central ridge bar of the polytunnel with cable ties with spray nozzles at 5ft apart. The spray nozzles are suspended from weighted drop-tubes to ensure they hang vertically for a "centred" spray area to cover the whole floor area.
Our irrigation kits are easy to fit to your existing polytunnel, taking a matter of minutes to install. All the parts that you need are supplied with the kit, ready to connect to your hose pipe with a "click connector".
The kit includes:
20mm LDPE Main Pipes
Pipe Cleats for fixing to the end frames
Drop-Tubes ensure centred spray area
Punch Tool for LDPE pipe
Ball Valve to operate irrigation system
Hose Connector for ½" hose pipe
All Connectors and fixings
