One of the main choices when buying a year-round growing space is whether to buy a greenhouse, or a polytunnel. Haygrove have put years of work into developing our garden polytunnels because we believe they have many more advantages over greenhouses. See how they compare below: |
 Greenhouse |
 Haygrove Garden Tunnel |
|||
| Site |
Must be flat |
Can be built on sloping ground |
|||
|---|---|---|---|---|---|
| Base |
Concrete base or slabs needed |
Anchored securely straight into the ground |
|||
| Portability |
Extremely hard to move structure and a new concrete base needed when changing site |
Although heavy, a Haygrove Garden Tunnel can be manually carried to another site |
|||
| Frame |
Usually wood or lightweight metal |
Industrial Grade Galvanised steel |
|||
| Repair |
Entire glass panes need replacement |
Easy plastic repair kits available |
|||
| Safety |
Glass will be dangerous when broken (not allowed in many schools and allotments) |
Plastic is strong enough to sit on, no risk if broken |
|||
| Cover |
Horticultural grade toughened glass is costly
Glass has poor light diffusing properties leading to plant scorching& shadowing
On bright days glass can be uncomfortable to work under |
Haygrove’s unique woven plastic covers diffuse approx. 88% of rays thus scattering light as it enters the tunnel allowing it to penetrate deep into the plant canopy without hot spots, scorching or shadowing.
The slight opaqueness of the cover makes it pleasant to work under even on bright days. |

| Ventilation |
Usually an expensive extra, can let in insects |
Included as standard, insect proof netting |
