What is a Lean-to Greenhouse?

A lean-to greenhouse is a type of greenhouse that needs support to lean on for a stable structure. Hence, the name is ‘lean-to’ greenhouse. This frame house has three sides and requires back support from a long wall or other structure.

  • Costs less than a four-sided greenhouse.
  • Portable options are available for easy shifting.
  • Weatherproof covers protect the plants from getting exposed to harsh elements.
  • Requires less space than a conventional greenhouse for their structured figure.

Buying Guides to Get The Top lean to greenhouses

Some particular features are the benchmark of the top-quality greenhouse. So, what are they? Let’s find out.

best lean to greenhouse kits

Material

The best lean-to greenhouses are made of standard materials to outstand their lifetime. However, a better material will definitely increase the cost but look for the sturdiest materials in a lean-to greenhouse. Most of them have a metal or aluminum structure and the sides are made of either plastic film or polycarbonate panels. And in winter, it prevents the plants from getting frozen.

Plastic: Plastic films retain enough heat for a greenhouse, but are not that durable. They are prone to wear and tear when exposed to harsh elements. And aren’t compatible with strong winds. But they are the cheapest option out there.

Polycarbonate: This material has a shatter-resistant capacity that makes them a more durable option than glass. It filters out Ultraviolet light excellently. However, they are opaque. So you can’t see through them. Pick at least 4 mm thick cellular polycarbonate for a three-season greenhouse or 8 mm for year-round use.

Glass: Though glass has a better heat retention ability than the previous two materials, it is prone to crack or break. However, glass greenhouses are classical and let you see through.

Size

You can find small, large, medium, and even customized sizes when looking for a lean-to greenhouse. You should pick the best fit for your requirement.

Ventilation

A greenhouse requires sufficient ventilation for temperature and humidity control. Because in summer it can get way too warm inside the greenhouse that is not good for the plants inside. So, ventilation is a must-have feature for a greenhouse.

Weather Resistance

Some areas have heavy snow, where some face heavy rainfall around the year. Greenhouses need to be made of durable material to endure the elements. Weather resistance is a must-have feature in any lean-to greenhouse.

Temperature Control

In a greenhouse temperature controlling is necessary for the proper growth of the plants. Too much humidity will make the plants droopy, excess cold temperature will kill them by freezing them. So, for regulating temperature you can use some tools. For example- a HAF fan that provides horizontal airflow, a heater to retain the minimum temperature for the plants to survive, and an automated watering system can keep the right temperature.

Warranty

The best product has the best warranty period, but some products may not have this facility.

FAQs

What side of the house should a lean-to greenhouse be on?

A lean-to greenhouse should be kept on the south side of the house having a supporting wall on the north side…

However, for a regular greenhouse, or the lean-to greenhouses that don’t require a solid and have a sturdy structure, the ridge of the roof should run east-west for an extended period of sunlight in the winter. But only for using it in summer and spring, it can run north-south for equal distribution of sunlight on both sides.

What is the best material to use for a greenhouse?

Mainly Polyethylene/ PE and Polycarbonate plastics are used as the covering of the greenhouse. And the frame can consist of various materials, like- aluminum alloy, stainless steel etc. However, the best covering material is Polycarbonate plastic and corrosion-resistant steel for the frame. They are considered to make a virtually unbreakable bond.

Are lean-to greenhouses good?

Everything has its good sides and bad sides. A lean-to greenhouse is no different. A lean-to greenhouse is good to hold against a solid structure or wall. These compact hothouses are compatible with small spaces and apartment gardening. And they have a better heat retention capacity than the regular greenhouse.

What can I grow in a greenhouse?

You can grow more or less everything in a greenhouse. Anything from vegetables to herbs, and even fruits and flowers.
