Bob lives in Arizona at 5,000 feet, on land that backs onto national forest. It is the kind of setting most people picture when they imagine leaving the city behind to grow their own food. The reality was harder than it looked.
Between the intense high-elevation sun, wind that defeats the usual fixes, and wildlife coming out of the forest after dark, his garden never really stood a chance out in the open. This year he changed that with a polycarbonate greenhouse. Vegetables are growing surprisingly quickly, and in his own words, he can enjoy gardening again.

1. Growing at 5,000 Feet Is Harder Than It Looks
The higher you go, the thinner the atmosphere, and the more ultraviolet light reaches the ground. At 5,000 feet the sun is noticeably more intense than it is closer to sea level, and that takes a toll on plants that would grow fine elsewhere. For Bob, that was the first obstacle.
"We live at a 5000 ft elevation, which makes it hard to grow vegetables here because of the UV light at this elevation. Most people try to shade their gardens with shade cloth, but it is very difficult here with the winds." - Bob, Arizona

2. Why Shade Cloth Isn't the Fix in the High Desert
The standard answer to too much sun is shade cloth. In a sheltered backyard, that works. In open, windy country it becomes a constant fight: fabric that has to be stretched, anchored, and re-secured every time the wind picks up, which at elevation is often.
Shade cloth also only solves one problem. It brings the light down, but it does nothing for the other two things working against a high-desert garden.
3. Raided After Dark
Bob's property sits right next to national forest, so his garden was on the route for whatever came out of it at night. Javelinas and deer treated open beds as an easy meal.
An open garden in that situation is a losing proposition. You put in the work, the water, and the waiting, only to find it gone by morning. Fencing helps, but a determined deer clears most of it and javelinas go under it.
4. How One Polycarbonate Greenhouse Solved All Three
A polycarbonate greenhouse answers all three problems with a single structure. The panels filter out most of the ultraviolet light, so the intense elevation sun stops being a liability. The solid frame and rigid panels stand up to the wind that made shade cloth impractical. And because it fully encloses the growing space behind a door, it keeps javelinas and deer out for good.
"The polycarbonate panels are created to stop the UV rays. Our garden was raided at night by Javelinas and deer, we live next to the National forest. We now have it planted and vegetables are growing suprisingly quickly! We can now enjoy gardening again, knowing the plants are protected." - Bob, Arizona
Bob is not the only one growing in tough Arizona conditions.
Mark made the same move from California to Arizona and built a polycarbonate greenhouse to grow year-round in the heat.
5. The Result - Gardening Again
The measure of any greenhouse is not the structure. It is whether it gets used. Bob went from a garden that couldn't survive the sun, the wind, or the wildlife to vegetables coming in quickly and a hobby he enjoys again, without bracing for what he would find each morning.
That is what the right structure does. It removes the conditions you cannot control and gives the plants, and the gardener, a fair shot.

Frequently Asked Questions
Is a greenhouse worth it at high elevation?
Yes. Higher elevations get more intense ultraviolet light and bigger temperature swings, both of which make open-air growing harder. A greenhouse filters much of that UV through its panels and creates a more stable environment, so crops that struggle outside at 5,000 feet can grow normally inside.
Do polycarbonate greenhouse panels block UV?
Yes. Quality polycarbonate panels are made with a UV-protective layer that blocks most ultraviolet light. That protects the panels themselves from degrading over time and shields the plants inside from the harshest part of the sun, which matters most at high elevation where UV is stronger.
Can a greenhouse keep out deer and javelinas?
Yes. Unlike shade cloth or open beds, an enclosed greenhouse with a solid frame and a closing door physically separates your crops from wildlife. For gardeners living near forest or open land, where deer and javelinas raid gardens at night, that protection is often the single biggest reason to grow under cover.
