MONT 8′ × 8′ Black Greenhouse
Premium Package

Year-Round Growing — Heavy-Duty Aluminum Frame — 10-Year Warranty

Everything the MONT 8′ × 12′ delivers — the same heavy-duty U.S.-grade aluminum frame, 8mm twin-wall polycarbonate panels, Premium Package features, and 10-year industry-leading warranty — in a compact square footprint designed for smaller yards, courtyard gardens, and sites where 64 square feet of growing space is the right scale. The complete system: structure, workbenches, shade, programmable irrigation, and the only built-in greenhouse sink on the market. Made in the USA.

10-Year Warranty Made in USA Year-Round Use Compact Square Footprint 8mm Twin-Wall Polycarbonate Expandable


8 × 8 Footprint 76 Peak Height 10 yr Warranty 64 sq ft Growing Space

Right-Sized for Smaller Spaces, Uncompromised on Quality

The 8 × 8 is MONT’s answer to a question most greenhouse manufacturers cannot answer well: how do you build a compact greenhouse that does not compromise on material quality, structural integrity, or feature set? Most smaller greenhouses cut corners on frame thickness, panel quality, or accessories to hit a lower price point. The MONT 8 × 8 does not. It uses the same U.S.-grade extruded aluminum frame with 40+ lbs more material than a typical import, the same 8mm twin-wall polycarbonate panels, and the same full Premium Package — just in a square footprint that fits where the 8 × 12 cannot.

At 64 square feet of growing space, the 8 × 8 is suitable for a serious hobby grower, a dedicated seed-starting and propagation operation, or a compact commercial planting setup on a constrained site. The 7-foot 6-inch peak height provides full standing headroom and the air volume needed for proper heat stratification — heat rises away from the growing zone rather than sitting at root level, keeping plant temperatures stable without constant manual ventilation.

The black electrostatic paint is lead-free, permanently bonded to the aluminum frame, and resistant to chipping, peeling, and corrosion through years of outdoor exposure. The automatic roof vent opener handles interior temperature regulation without a power connection or manual adjustment, opening as heat builds and closing as it dissipates. Expandable with 4-foot extension kits whenever growing demands outgrow the current footprint.


What the Premium Package Includes

Everything in the base greenhouse, plus: ●  Commercial workbenches — one side fitted with durable workbenches for potting, propagating, and daily growing tasks — maximizing usable workspace in the compact footprint
●  Interior shade system — adjustable shading that protects plants from peak-intensity sunlight without blocking beneficial growing light; essential for summer use in the 8 × 8’s more concentrated interior
●  Programmable watering system — schedule irrigation precisely for each growing zone; reduces daily labor and improves consistency across the full growing area
●  Built-in greenhouse sink — the only greenhouse on the market with an integrated sink; eliminates the need to carry water or move tools in and out for cleaning tasks

Structure & Features

Heavy-Duty Aluminum Frame

U.S.-grade extruded aluminum with 40+ lbs more material than typical imports. Black electrostatic lead-free paint permanently bonded against peeling, chipping, and corrosion. Built to handle snow loads and wind pressure year-round.

8mm Twin-Wall Polycarbonate Panels

Double-wall panels trap an insulating air layer — equivalent to double-pane glazing. UV-stable construction prevents yellowing. Keeps interior temperatures stable across seasons and reduces supplemental heating costs in winter.

Large Lockable Double Doors

Hinged double doors approximately 6 ft high × 4.5 ft wide — wide enough for wheelbarrows and large containers. Updated new-design door hardware for smooth, secure operation. Lockable for security and doubles as the primary ventilation opening.

Automatic Roof Vent Opener

Temperature-activated vent opens automatically as interior heat builds and closes as it dissipates. No power connection or daily manual adjustment needed — passive ventilation that protects plants without requiring attention.

Integrated Base & Dual Rain Gutters

Built-in base frame provides a stable foundation and anchoring points for expansion kits. Dual rainwater gutters channel runoff away from the base — connectable to a collection barrel for water reuse in the programmable irrigation system.

Expandable with 4′ Extension Kits

Optional 4-foot extension kits allow the 8 × 8 to grow alongside your growing operation — extending the footprint as demand increases without replacing the existing structure. Plan the initial siting to leave room for future expansion.

7′6″ Peak Height — Full Headroom

The 7′6″ peak provides comfortable standing headroom across the full interior and the air volume required for proper heat stratification — critical in a compact footprint where heat management is more demanding than in a larger structure.

10-Year Warranty — Industry’s Strongest

10 years on frame and panels — the strongest coverage in the residential greenhouse category. Applies equally to the 8 × 8 as to the larger MONT models. The same structure, the same materials, the same warranty.

Buyer’s Notes — What to Know Before You Order

8 × 8 vs. 8 × 12: If your site can accommodate the 8 × 12, the extra 48 square feet of growing space is almost always worth it for serious growers. The 8 × 8 is the right choice when site dimensions, budget, or intended use genuinely call for a compact square format. Both carry the same frame quality, panel spec, and Premium Package.

Ground preparation: A level, stable surface is required before assembly begins. Concrete pad, gravel base, or pavers are common choices — ground prep is the buyer’s responsibility and is not included in the kit.

Heat management in a compact space: The 8 × 8’s smaller interior volume heats up faster in summer than the 8 × 12. The interior shade system and automatic roof vent are both more important in this format — they are included in the Premium Package for exactly this reason.

Permits & expansion planning: Check local building codes before installation. If you anticipate outgrowing the 8 × 8, site it with clearance for a 4-foot extension kit at one end — adding the kit is much easier before the structure is anchored than after.
