Description
Jump To:
The MONT Greenhouse – Growers Kit is built for gardeners who care most about plant performance. The big upgrade is the glazing: light-diffusing 8mm twin-wall polycarbonate that spreads sunlight more evenly across the greenhouse.
That “even bright light” is a game changer for growing. It helps reduce harsh hotspots, supports more uniform growth, and makes the greenhouse easier to manage on high-sun days—especially when paired with the included climate-control accessories.
A quick note on the name: MONT greenhouses were previously known as Monticello. The name was updated, but it’s the same greenhouse line (and in some cases improved). So if you’re searching for a “Monticello greenhouse,” you’re in the right place.
Better Light for Better Growth
Light-diffusing polycarbonate doesn’t just “look softer”—it changes how plants receive light. Instead of intense beams and bright hotspots, you get more even, bright light across the canopy.
That means fewer scorched leaves in harsh sun and more consistent growth across benches and beds—especially helpful when you’re growing a mix of crops at different heights.

USA-Made Frame You Can Trust
MONT uses thicker extruded aluminum framing that’s made in the USA and built for long-term outdoor use. It’s a practical structure designed for daily gardening life—opening doors, venting, and working through the seasons.
Ready-to-Use Growing Kit
This package is designed to help you hold steadier conditions—so you can start earlier, push later, and keep plants happier when weather swings.
Active & Passive Ventilation
An electric exhaust fan helps move hot air out quickly and keeps air exchange more consistent on warm days.
Automatic roof venting is included as well—an easy, hands-free way to release heat up high on sunny days.
Heating Support
A commercial greenhouse heating system helps you maintain growing momentum when nights turn cold—especially valuable for early starts and shoulder-season growing.
Water + Work Setup
A drip irrigation system plus a full-length foldable workbench make daily greenhouse routines easier—watering is more consistent, and tasks stay organized.
Expandable Design (Start Now, Grow Later)
One of MONT’s biggest advantages is that it’s expandable. If you’re not ready to commit to a huge footprint today, you can start with a smaller size and add 4′ extension sections later—without replacing the whole greenhouse.
It’s a practical way to avoid the classic regret of “I wish I went bigger,” while keeping the upfront investment manageable.
Secure Close-Up Hardware
When weather turns, it’s nice to be able to button everything up quickly—and know it’s going to stay put. MONT’s updated locking hardware adds extra peace of mind on windy days, without making day-to-day use complicated.
More Secure Double Door
The hinged double doors use a more substantial locking system with a bar-style mechanism you can engage and disengage easily. It creates a tighter, more secure close—especially helpful in gusty conditions and for everyday peace of mind.
Lockable Roof Vents
On very stormy days, you can lock the roof vents down for extra security. Many greenhouse lines treat this as an add-on upgrade—MONT includes it as part of the updated design so you can secure the greenhouse fast when weather gets rough.

What foundation do I need?
Picking a level site is the best first step. It is important that the foundation is level and strong enough to hold the greenhouse. A concrete slab or a concrete perimeter wall will provide the most solid, long-lasting base. The key is that your foundation is level, square, and well-draining—even small twists can affect door operation and panel fit.
Helpful guides:
Do the roof vent openers require electricity?
No. They are wax-cylinder openers, which expand and contract with temperature to open/close the vent—so there’s no wiring and no power required.
