A proper greenhouse ventilation program is incredibly important to any grow operation, whether or not you’re a hobbyist with a smaller sized structure or a industrial 
farmer whose massive house protects their livelihood.
Our greenhouse hands crank can roll up sidewalls up to 300 foot long. It does so with a long lasting construction of stainless in a plastic material resin casing made to fight off long-term corrosion and use. What’s more, it’s 4:1 gear ratio makes for easy cranking and it’s really Manual Roll Up For Greenhouse self-locking, automatic brake will make sure that your sidewall will stay where you want it to.
With this hand crank, you’ll be able to control the temperature and humidity of your greenhouse. It also gives you side access to both your low and high tunnel hoop houses. It’s even simple to install; just follow these guidelines for guidance about how to integrate this greenhouse curtain crank in to the creation of your greenhouse.
You can’t control the elements, but you can have all-weather control of your greenhouse with our complete roll-up curtain program. Our system contains everything you will require for years of continuous operation. No lumber to get, no extra poly fasteners to get; our cost includes everything. Furthermore, you can choose a manual crank or an incrementally automatic system. Our fabric is certainly a heavy-duty 12 mil. coated 10’x10′ weave fabric (not really 6 mil. poly), strong enough to withstand the abuse of windy conditions and actually rocks thrown by lawn mowers and weed-eaters. Growers prefer curtains that roll up from the middle instead of rolling up from the bottom; crank rotations are reduced by 50%, and curtains are kept straight. Affordable and easy to operate organic ventilation and also adaptable to any greenhouse with directly sidewalls.
Roll-up sides have quickly become the cheapest cost way to ventilate greenhouses, high tunnels and hoop homes.
While most growers want roll-up sides for their structures, the hardware components associated with roll-ups can often be frustrating. Hopefully this post can help make roll-up side installation simpler.
