Manual Blackout Systems
20' Hoop Structures
Our Manual Blackout Kit includes:
- Everything that comes standard in our greenhouse kits: hoops, purlins, framed out end walls w/ door, clear plastic and manual roll up sides
- Black on white, 8 mL 3 ply thread reinforced polyethylene that is rated for up to 3 years. This plastic allows for you to totally blackout your greenhouse but still refract excess heat by having the white side facing out towards the sun.
- Galvanized steel piping to run the length of your greenhouse for fastening the blackout tarp to you greenhouse and for the blackout tarp to roll up on.
* On our light deprivation blackout kits, the end walls are blacked out out at all times to avoid any light leaks. Not rated for use in snow.
