Nelke 4 Pro Growing Greenhouse | Built for Serious Gardeners

by KGT/Hoklartherm

This greenhouse presents the pinnacle of the growing greenhouse category, a product shaped by more than four decades of German greenhouse engineering.Purpose-built for serious gardeners, hobby farmers, and outdoor enthusiasts who want to extend their growing season through every month of the year, this ProGreenhouse is the smart design choice for those who demand both beauty andbulletproof performance.

Top German Engineering You Can Count On

KGT has refined its greenhouse manufacturing process over 40+ years, and the Nelke 4 Pro is the result of that
expertise. Every component, from the precision-extruded aluminum frame to the tight gasket sealing, reflects top German engineering standards. The traditional A-frame gable-front design isn't just stylish; it maximizes interior headroom (8 ft. peak height) and sheds snow efficiently in high-load climates. An optional decorative finial cresting adds a distinctive architectural finish that sets this growing greenhouse apart in any backyard.

Smart Design for Year-Round Growing

The Nelke 4 Pro's smart design thinking shows up in every detail. The 16 mm triple-wall polycarbonate glazing provides outstanding insulation, far superior to single or twin-wall panels, keeping your growing greenhouse warm when temperatures drop and filtering harmful UV rays in peak summer. Two automatic roof vent openers regulate
temperature and humidity without any manual intervention, opening and closing based on the interior temperature. A rear backwall window creates balanced cross-ventilation, so your plants enjoy optimal airflow regardless of outdoor conditions. The result is a stable, controlled growing environment that extends your season by months on both ends.

Heavy-Duty Aluminum Frame Built for Harsh Weather

The extruded aluminum frame of this Pro Greenhouse is engineered to handle serious loads. Reinforced snow-load supports mean you won't be worrying about your greenhouse after a heavy Colorado snowfall. Aluminum resists rust, rot, and corrosion indefinitely, no painting, no treating, no seasonal maintenance. The anthracite powder-coat finish gives the Nelke 4 Pro a sleek, modern look that complements any landscape design. With a 20-year aluminum warranty and a 15-year polycarbonate warranty, this growing greenhouse is built to be the last one you'll ever need.

Designed for Comfortable, Accessible Gardening

• At 9'8" wide and 14' long, the Nelke 4 Pro greenhouse delivers 135 sq. ft. of usable growing space, enough for raised beds, potting benches, shelving, and comfortable movement.
• The 5'3" sidewall gutter height means you won't be stooping at the edges, while the 8' peak gives generous headroom for tall plants and hanging baskets.
• The 37" Dutch barn-style door is rated ADA accessible, making entry and exit easy whether you're rolling in a garden cart, carrying large containers, or navigating with mobility equipment.

Smart design means this greenhouse works for every gardener.
