What is NookGrow built to be?

Plants need more than sunlight—they need a place where they can grow in safety. Yet in the real outdoors, cold snaps strike quickly, spring is rarely warm, and autumn slips away too soon. What you truly need may not be an expensive greenhouse, but a small haven that can shield a little wind, hold a little warmth, and protect your plants through the night. A home for your plants is also the starting point of your outdoor life.

Garden with wooden raised beds, plants, and flowers in a backyard setting.

We listened closely to our users:

Need more stability? — We added a galvanized metal raised bed.
Need a taller growing space? — We added the structure to a peak-roof form.
Need better ventilation control? — We created dual-opening windows.
Need longer growing seasons? — We thickened the polycarbonate panels to retain warmth even longer.

NookGrow is more than a series of product upgrades. It is our step-by-step answer to building a true home for plants—a sheltered, welcoming space where growth feels effortless.

NookGrow is committed to lowering the barriers of gardening and widening the boundaries of each season. With protection from wind and frost, plants continue to thrive as the weather turns. As the seasons cycle on, your gardening journey keeps moving—because with NookGrow, your rhythm becomes the rhythm of nature.

The journey behind NookGrow

If extending your growing season ever felt hard, NookGrow’s evolution might surprise you.

NookGrow Ground: Starting with a Simple PC Cold Frame Cover

We started with the most basic questions: - How to provide seedlings with extra warmth in spring and autumn？ - How can it be used by gardening novices without any experience？ The answer was a simple yet essential cold frame cover—Ground placement, bottomless design for natural soil rooting and healthier growth. It allowed countless families to extend their growing season for the first time.

Wooden cold frame with a transparent cover, water being sprayed onto it, and an inset showing a close-up of the cover's material.

NookGrow Elevated: Making the Structure More Stable, Making Use Easier

We added galvanized iron sheet planter beds. This means: - The planter bed is no longer just a "cover," but an 2-in-1 elevated vegetable garden; - More stable, resistant to wind; More durable, resistant to damp soil erosion of the wood. No outdoor vegetable garden is needed; just fill the pot with enough fertile soil, and you can have your own vegetable garden even on your city balcony.

NookGrow Peak: From Cold Frame Bed to Mini-Greenhouse

We added a second skylight, and the roof changed from a sloping roof to a pointed roof. - The gable roof provides better drainage and greater interior space; - Double windows offer more flexible ventilation control. The overall design also presents a "mini-greenhouse" feel for the first time. This is not just a functional upgrade, but an upgrade in the imagination of outdoor living. But NookGrow will not stop there...

NookGrow Extend: More than just home garden systems

We have been compiling user suggestions and needs and continuously improving: - Thickened the PC board to 5mm; - Extended the overall structure to 122cm, allowing for planting more at once; - Made the cold frame and plant bed completely separable, achieving a dual-season system with the roof on in spring and autumn and open in summe; - Continuing to use the galvanized steel and cedar wood structure makes the entire flower bed more stable, durable, and safe, even suitable for raising chickens in winter.
