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.

Nelke 4 Pro Greenhouse FAQ
How much snow load can it handle?
More than most polycarbonate greenhouses its size. Collar-beam turnbuckle cross supports reinforce the aluminum A-frame against snow, a real advantage in cold-winter climates.
Why triple-wall polycarbonate instead of twin-wall?
16mm triple-wall panels have an extra air channel, so they insulate better. That matters if you want to grow through winter, not just stretch the season.
Do I need a foundation?
It needs a level, secure site. The aluminum foundation frame is included free with your order, so you don't have to pour a concrete strip foundation unless you want to.
How wide is the door? Will my wheelbarrow fit?
Yes. The 38" barn-style door (71" tall) is ADA compliant and much wider than most hobby greenhouse doors.
What's the warranty?
20 years on the aluminum frame and 15 years on the polycarbonate panels (prorated after year 10). Call or text us at 732-806-7959 if you ever need to file a claim.
