A proper greenhouse ventilation system is incredibly important to any grow operation, no matter whether you’re a hobbyist with a smaller structure or a commercial farmer whose massive house protects their livelihood.
Our greenhouse hand crank can roll up sidewalls up to 150 feet long. It does so with a durable construction of stainless steel in a plastic resin casing designed to fight off long-term corrosion and wear. What’s more, its 4:1 gear ratio makes for easy cranking and self-locking. The automatic brake will ensure that your sidewall will stay where you want it to.

Why Ventilate your Greenhouse?
Greenhouse Cooling and Humidity Control
Controlling greenhouse humidity with some ventilation system is a must in just about any climate. Even in cooler climates, greenhouse temperatures can reach extreme levels. Your plants are more likely to die in a greenhouse from excessive heat than cool temperatures.
Pests and Disease Prevention
Proper greenhouse air circulation is also critical for healthy plants. By rolling up your side curtains you allow stale air to get pushed out of your greenhouse leading to healthier plants with fewer disease and pest problems. Many common greenhouse pests and diseases thrive on stale and humid air. Rolling up your sidewalls will allow air to circulate, naturally reducing incidences of these common problems.
Better Pollination
Growing in a greenhouse without natural air circulation can cause poor pollination of your plants. A breeze naturally sends pollen around your greenhouse so you can avoid the hassle of hand-pollinating every plant. If you are noticing poor pollination or poor fruit setting, this is a sign that you may need to be increasing the airflow into your greenhouse.
Keeping Your Greenhouse Ventilated
During the hot summer months its critical to keep your greenhouse well ventilated. In our area at the southern coast of North Carolina we get average highs in the lower 90s with high humidity. Without proper greenhouse ventilation temperatures inside can easily exceed 115°. To keep your plants cool during periods of high heat we simply just roll up our sidewalls and keep both end wall doors open. This allows air to naturally keep our greenhouse cool and our plants safe from excess heat.

Love this Compost! My garden does great every year and it's because of
this great Compost Mix. I would not use anything else.
Great dirt and great communication
Started a new garden and it seems to be helping all of my new starter plantings
Product was great! Ordered some seeds as part of a gift along with a gardening apron. Was a quality item, arrived quickly and it was a big hit!
Super fast service and answered all my questions!
Great service each time I used them, 3 times now.
He delivered great organic topsoil the same day. Excellent subsurface for sod. Friendly and fast, very careful during delivery.
The mulch was great. No junk in it like the bagged stuff. AsS with all outdoor projects weather is a thing. They were understanding of delays and changes.. And when the day came for delivery, there was plenty of communication and showed up on time. Plus the price was right!
I am very happy with my soil purchase! Great company to do business with! I highly recommend!
It works well. I just wish it had some residual to it so I wouldn't have to spray every few weeks.
Good and high quality, best pants from a soil company ive ever bought.
If you want a quick turn around when ordering soil, this is your guy. If you want someone to dump soil where YOU want it, this is your guy. If you want someone to sell you good soil instead of sand and broken up pallets, this is your guy. It seems weird that a guy and his wife would be so excited about dirt, I know. But we were. It’s the beginning of a big transformation for our house. So we ordered this, I think on and Saturday and surprisingly he said he could deliver it on Monday! So Monday, we woke up and literally wished each other a happy dirt day. I went to work and sure enough, he showed up on time and dumped the dirt exactly where we were hoping. And when I got home I walked over and before I could get there, you could smell the organic material in the dirt. Our plants will love this. Excellent quality. Excellent transaction. Excellent service. Couldn’t be happier.
Happy with the soil and delivery was when expected, would use again
