Proper ventilation is one of the most important factors in greenhouse performance, and nothing controls airflow as simply as a roll-up side system. Build My Own Greenhouse's Roll-Up Side Kit gives you everything you need to add manual sidewall ventilation to a new or existing greenhouse structure.
Whether you're managing summer heat, humidity, or simply want the ability to open your greenhouse sides on demand, our greenhouse roll up side kit is the practical, low-cost solution trusted by hobby growers and commercial operations alike.
Greenhouse Sidewall Ventilation Made Simple
A roll-up side system works by allowing the lower sidewall covering of a greenhouse to be cranked upward, opening the sides for passive airflow without fans, electrical wiring, or complex vent mechanisms. It's the most widely used greenhouse ventilation kit approach in hoop house and gothic greenhouse construction — reliable, affordable, and easy for any builder to install.
Whether you call it a greenhouse roll up curtain kit, a hoop house roll up side kit, or simply roll up sides for greenhouse ventilation, the function is the same: fresh air in, excess heat and humidity out, on your schedule.
Our Roll-Up Side Kit includes the swivel assemblies and crank hardware needed to make it happen. Choose the configuration that fits your build.
Why Growers Choose Our Roll-Up Side Kit
Greenhouse Ventilation Without Electricity
Roll up sides for greenhouse use require no power. That makes our greenhouse ventilation kit an ideal solution for off-grid growing operations, remote hoop houses, and any situation where running electrical to a greenhouse fan isn't practical or desirable.
Compatible With Hoop House and Gothic Arch Frames
Our roll up side kit for hoop house and gothic arch frames works with the most common DIY greenhouse frame styles. If you're building from one of our connector kits, adding roll-up side hardware is a natural next step toward a fully functional growing structure.
Multiple Configuration Options for Any Greenhouse Length
We offer a single swivel hand crank assembly, a double swivel U-joint and handle set, a no-handle single swivel, and a crank handle only option, so you can build a greenhouse roll up side kit matched exactly to your greenhouse length and layout. Order a complete assembly or source individual roll up side hardware components as needed.
Easy to Install on New or Existing Structures
Whether you're adding greenhouse crank roll up sides to a new build or retrofitting an existing structure, installation is straightforward and doesn't require specialty tools. Most growers can complete a full roll-up side installation in a few hours.
Frequently Asked Questions About the Roll-Up Side Kit
What is a greenhouse roll up side kit?
A greenhouse roll up side kit is a set of crank hardware and swivel assemblies used to create a manually operated sidewall ventilation system. By turning a crank handle, the lower sidewall covering rolls up on a pipe, opening the greenhouse side for airflow. It is one of the most common and cost-effective greenhouse ventilation kit options for hoop houses and gothic greenhouse structures.
Why use roll up sides for greenhouse ventilation instead of fans?
Roll up sides for greenhouse use provide passive ventilation that responds immediately to temperature changes and requires no electricity. They're especially effective in warm climates and during summer months, when open sidewalls allow breezes to move through the structure freely. Many growers use a greenhouse roll up curtain kit as their primary warm-weather ventilation and supplement with fans only during extreme heat.
What's the difference between a single swivel and a double swivel U-joint assembly?
A single swivel hand crank assembly is suited for shorter greenhouse sidewalls where a single crank point provides sufficient coverage. A double swivel U-joint and handle set is designed for longer sidewalls or situations where the roll-up pipe needs to be driven from a central point with more mechanical advantage. The length of your sidewall is the main factor in choosing between the two.
Is this a good roll up side kit for a hoop house?
Yes. Our roll up side kit for hoop house frames is one of the most straightforward ventilation upgrades you can make to a standard hoop structure. The hardware is compatible with the most common hoop house frame styles and installs without modifying your existing frame.
Does this greenhouse roll up side kit work with any covering material?
Roll up sides are most commonly used with standard greenhouse poly film. The covering attaches to a pipe at the base of the sidewall, which rolls up when the crank is turned. The roll up side hardware in our kit is compatible with most single- and double-layer poly films used in hoop house and gothic greenhouse construction.
Can I add roll up sides to a greenhouse I already built?
Yes. Our greenhouse sidewall ventilation hardware can be retrofitted to most existing hoop house and gothic arch frames without major modifications. As long as you have a bottom rail or baseboard pipe to attach the roll-up pipe to, installation is straightforward.
What other supplies will I need?
Most roll-up side installations also require a pipe or conduit to serve as the roll-up bar, base rail hardware, strapping or zip ties to attach the covering to the roll-up pipe, and wiggle wire channel to secure the top edge of the sidewall covering to the frame.
