The Nelke 4 Pro is Hoklartherm’s insulated A-frame greenhouse, built for gardeners who want to grow through the winter, not just extend a few weeks on either end. 16mm triple-wall polycarbonate panels have UV protection built into the material itself rather than a coating that can wear off, and the A-frame profile sheds snow far better than a flat-roof design.

Includes a free aluminum foundation frame — a sturdy anchored base that keeps the structure level and secure, normally sold as a separate accessory elsewhere. It’s included with every Nelke 4 Pro from us at no extra charge, so there’s nothing else to add to cart before you order.

Dual automatic roof vent openers and a rear manual window handle day-to-day ventilation, while reinforced roof support with collar-beam turnbuckles is engineered for heavy snow loads. The extra-wide 38-inch barn-style door (71 inches tall) is ADA-compliant, so it’s an easy in-and-out even with a wheelbarrow or a wheelchair.

One size — 14′ x 9’8″, 102 sq. ft. — available in natural aluminum, fir green, or anthracite grey framing.
