What Types of Greenhouses Are There?

Greenhouses are structures made of glass or other transparent materials. They come in different sizes, depending on the function they serve. A glasshouse can be a small outhouse in the garden of a family home or an industrial-sized premise.

They can be found in three main types:

Starters

These units are small to medium-sized. They are used for germinating and hardening off plants. They take care of the seedlings until they are ready to be transplanted.

Pros:

  • Excellent for small space
  • Low cost
  • Easy to set up

Cons:

  • There are better options for experienced growers
  • Limited functionality

Cold Frame

Cold frames are bottomless units. They have a glass-roofed enclosure that protects plants from unfavorable weather.

Pros:

  • Light and portable
  • Practical
  • Ideal for cold temperatures

Cons:

  • The frames might overheat
  • Not the best for arid climates

Growers

Growers are the largest among the glasshouses. They serve different functions such as germination, tending of plants, and harvesting of grown greenery.

Pros:

  • Versatile
  • Large size
  • Ideal for growing large plants

Cons:

  • Hard to fit into small houses
  • Not great for small veggies

What to Consider Before Buying a Greenhouse

There are some aspects that buyers will need to bear in mind before making a final choice. No matter what kind of unit they are inclined to, this information will help them make a more informed decision.

Right Size

Greenhouses come in all shapes and sizes. It is important to choose the structure that is best suited for a specific purpose, and that fits the available space.

Oxygenating

Airing is a crucial aspect of greenhouses. Without proper ventilation, crops might never reach their full potential. Whether they choose natural or fan oxygenation, users will need to choose a system that is efficient, user-friendly, and not too costly.

Insulation

Preventing crops from losing heat is a crucial part of vegetable growing. Users can choose among different options, such as double glazing, bubble plastic protectors, and thermal screens. All three of them are very efficient systems and will help plants grow strong and healthy.

Adjustability

It’s important to bear in mind that too much heat or too much cold can harm crops. The suggested temperature for a glasshouse ranges from 80 to 85 degrees Fahrenheit. Therefore, buyers should consider additional heat sources if they want to optimize their greenery.

Lightning

The ideal lighting for a greenhouse depends on three crucial aspects: the kind of greenery being grown, climatic conditions, and the amounts of natural daylight available. Most units normally need to be exposed to the sun for five to seven hours every day

Irrigation

An efficient watering method is crucial for successful gardening. Different systems of irrigation depend on weather conditions, the size of the unit, and the kinds of plants being grown. Buyers should approach an expert on the subject before making a choice.

Durability

This is an essential aspect to consider before purchasing a greenhouse. It should be noted that durability will depend on the quality of the materials used for construction, and their ability to resist unfavorable weather conditions

Cost

Greenhouses can be found at different prices depending on their size, quality, and resilience. For beginners who just want a small glasshouse in their garden, a low-priced will do. Those looking for an industrial unit, however, will have to make a bigger investment.
