Affordability and extended durability are the most evident features of our 6m(20ft) x 3m(10ft) polytunnel and 3x6 polytunnel.But they also have many unique advantages,such as:
-
BUDGET-FRIENDLY COMMERCIAL GREENHOUSE
The greenhouse size is appropriate for commercial farming, but saves on materials & maintenance costs. As with any other low-tech greenhouse, its purchasing cost is low but performs over years on end.
-
JUST THE RIGHT AMOUNT OF SPACE
6m wide tunnel greenhouse span provides enough space for multiple growing rows and access paths. Proper row spacing supports better plant growth. But leaving enough room between rows for access paths and using trolleys, carts, and harvest tools is key to efficiency. Greenhouse owners can maintain wide central paths for trolleys, carts, or small machinery while still maximizing planting area.
-
INCREASED CONTROL OVER CLIMATE
Our 20ft polytunnel kits are not as high as other high tunnel greenhouses. Plus, they can be equipped with large doors at both ends. If greenhouse ventilations is still an issue, DELITE also delivers roll-up side options. Overall, our kits are less exposed to moisture and heat buildup. Because of its controlled volume, the 6m wide hoop greenhouses are easier to ventilate and do not require as much energy to heat up or cool down. Temperature and humidity are easier to regulate compared to larger greenhouses.
As a residential greenhouse made with Professional polytunnel materials, polytunnel 3m x 6m and 6m x 3m poly tunnel have demonstrated a remarkable performance. In terms of the size of our polytunnel greenhouse, 6m x 3m poly tunnel and 6x3 polytunnel are very common ones.

What is the difference between 6 meter polytunnel and 6x3m polytunnel
The differences between 6 meter polytunnel and 6x3m polytunnel are evident. For 6x8 green house, it can be seen as commercial greenhouse. While 3m wide greenhouses are normally for residential purposes. End-users are also different. Compared with 3m wide greenhouse, 6m wide greenhouses are wider, higher and longer, which brings larger cultivating area for plants. Farmers and those who want to grow in a larger scale are likely to choose 6 meter wide greenhouse. 3m wide greenhouses are preferred by hobbyists and individuals. When it comes to the price, commercial greenhouses usually require a higher budget. The steel frame with greenhouse plastic bring along with it a strong and durable structure. 6m wide greenhouse has better performance and durability.
