If you're new or looking to advance or just
try out your gardening skills then buying a small garden or medium to larger domestic
polytunnels is a game-changer. These structures and covering help provide a micro-climate
environment for whatever crops and plants you want to grow, protecting them
from the elements, and extending growing seasons. If you're new to gardening
and growing methods, here's what you should look for when purchasing small, medium,
and larger-sized structures. How to install, and construct them, how to
approach and make polytunnel repairs immediately they appear, and what to be
aware of in the case of repairs and renewals.
Factors when purchasing small to large
polytunnels
Plan first: Preparation is required on both
where the structure will be located and also clearing and soil prep before
installation and what you intend to cultivate.
Size: Determine the size based on the
available space and the number of crops and plants you wish to grow. Smaller
models are suitable for beginners and small garden areas, while larger domestic
polytunnels are ideal for more extensive cultivation of produce, especially
considering the growing height and side areas of the structure.
Frame Material: Polytunnel frames can be made
from galvanized steel, aluminium, and even plastic tubing for mini, or small
hoop housing. Un-protected galvanized steel is sturdy but left untreated or uncoated
it could rust over time, while aluminium is lighter and corrosion-resistant,
this does come down to the commercial build size and customer preferences.
Covering Material: Polytunnel covers made out
of polyethylene or polyvinyl chloride Both of these materials are durable, but
have different strengths, polyethylene is more cost-effective, while PVC does
offer better insulation at a cost. Different quality covers are available in
various grades, gauges, and film thicknesses called microns these are added
during the manufacturing process, as well as other additives with associated
properties. There are both standard and UV-stabilised offerings.
Ventilation: Adequate ventilation is crucial
for maintaining the related temperatures and humidity within the garden or
domestic polytunnels. Always look for models with vents or windows that can be
opened and closed as needed, bespoke builds to specific requests are available.
Doors: Consider the type and how many doors
you require. Some polytunnels have roll-up doors and sides, while others have
hinged or sliding doors. Ensure the door design suits your access needs.
Budget: Set a budget that suits your
gardening options and choose a structure that offers quality and value within
your price range. Make sure that the polytunnel you choose does not include
inferior materials and covering, or else your cost for polytunnel repairs could
skyrocket, or need a complete replacement within a year or two!
Be prepared: Polytunnel repairs due to the
material nature will at some stage be required, so it’s worth purchasing the required
tapes and supplies, for those important repairs.
Installing and Constructing Garden or
Domestic Polytunnels:
Prepare the Site: Choose a level and
well-drained location for your sized project, and remove any obstructions, rocks,
debris, or weeds and branches that might interfere with construction or
covering.
Frame Assembly: Have the tools and equipment
ready. Follow exactly the manufacturer's instructions to better assemble the
frame. This could involve connecting the frame's arches, ribs, and bars
securing them correctly in place.
Anchor the Frame: To prevent the polytunnel
from being blown away by strong weather and high winds, anchor the frame
securely to the ground. Anchoring methods can include trenching, stakes,
concrete or metal anchors, and even sandbags or timber rails, there are many
cost-effective ways to secure a covering on domestic polytunnels and the
various build sizes.
Cover Installation: Stretch the polytunnel
cover carefully over the frame, avoid any snagging always get help if the cover
is unmanageable for one person. Ensure it is evenly distributed securely taut
and fastened to the frame and or rails using bungee cords, clips, or fasteners
and fittings provided by the manufacturer. Do consider how you would prefer the
covering to be fastened and anchored.
Door and Vent Installation: Attach the doors
and vents to the instruction list. Ensure they are in good order and they open
and fasten correctly, as they play an access and ventilation role in helping to
maintain the growing environment.
Ventilation: Adjust vents or windows to
regulate inside temperature and humidity. Good ventilation is essential to
prevent overheating and other growth issues.
For anyone new to buying or owning either a
garden or domestic polytunnels, it's important to understand that polytunnel
repairs may be required and periodic maintenance and occasional checks for
cost-saving repairs, will offer greater longevity.
