Best Large Greenhous Kits for Large Scale Growing


Are you looking to scale your garden or growing? Don't worry we have exactly what you need. In this post, we will go over the best large greenhouse kits on the market to help you scale your growing quickly and effectively.

Just because you want to scale your growing doesn't mean you need to build a large custom greenhouse. There are many large greenhoust kits on the market; wether you are looking for affordable or durable we've got you covered. 

Let's get started.


Why get a greenhouse in the desert or for hot weather?

Greenhouses are useful in the desert and hot climates because they provide protection for your plants and flowers from the high temperature during the day and cold temperatures at night. 

Greenhouses provide flowers and plants with necessary shade, sources of water, and temperature control in the desert or other hot weather environments. 

Flowers and plants can’t survive prolonged exposure to high temperatures. In addition, oftentimes in the desert and during other hot weather climates the temperature at night can also get very cold. 

This drastic change in temperature as well as the low temperature at night can be harmful to your plants.


What temperature is too hot for plants?

Temperatures above 90 degrees Fahrenheit are generally too hot for most plants and flowers. At prolonged exposure to 90 degrees, many plants will begin to wilt, flowers will drop off, and they will begin to die due to loss of water. 

Now there are certain species of plants that can handle higher temperatures and others that will begin to experience negative effects at lower temperatures. This is why it’s important to know the ideal temperature for your plants. 

In general, if plants are exposed for short periods to high temperatures they can typically survive without issue. This is because plants have water and food reserves to help them survive harsh temperatures. 

The issue arises when plants and flowers are exposed to high temperatures for extended periods of time. For extended periods, plants don’t have enough water, food reserves, or the ability to regulate their temperature to survive.


Key Features of a Greenhouse for Desert Climate or Hot Weather

There are a few key features that are important for a greenhouse that will be used in desert climates or hot weather. Many of the features required for a cold-weather greenhouse are the same for a desert climate. Those key features of a greenhouse

When choosing a greenhouse for the desert climate or hot weather there are a few key features that need to be considered: 

  • Panel Material
  • Panel Thickness
  • Panel Glazing 
  • Temperature control system
  • Vents

Panel Thickness and Panel Material

Panel Thickness and Panel material are one of the most important features of a greenhouse for the desert climate. The main reason is that panel thickness and the panel material determines how well the greenhouse is insulated. 

Insulation in a greenhouse is important because it protects your greenhouse from the weather outside. The more effective your insulation the less your greenhouse interior temperature will be affected by the temperature outside. 

When choosing a greenhouse for hot weather you want a greenhouse that uses a thick wall such as polycarbonate or tempered glass. Both of these panel materials are highly durable and effective insulators. 

When choosing panel thickness you typically want panels that have a double wall. Double walls provide more effective insulation than single wall panels. When choosing polycarbonate panels at the minimum you want 4mm twin-wall panels but an ideal thickness is around 8mm twin-wall. With tempered glass panels you want around 4mm double-pane or 6mm double-pane.

Panel Glazing

Panel glazing and light transmission is an important aspect of a desert climate greenhouse. This is an important factor because it influences how much light hits your flowers and plants. 

With heavy and strong sun it's ideal to have some degree of glazing and around 80% light transmission so your plants don’t get too much sun. Another way to reduce the level of sun that your plants receive is to use a shade cover. A shade cover is a dark, transparent cloth that goes over your greenhouse to reduce the amount of light that can enter.

Temperature Control System

The temperature control system of your greenhouse is very important to managing the temperature inside your greenhouse. This is because your greenhouse will typically need assistance managing the harsh temperatures of the desert climate. 

One of the most basic forms of temperature control is a roof vent or louver. Both of these help you manage the temperature by controlling airflow. 

But, often times desert greenhouse might require additional temperature control equipment such as misting systems, exhaust fans, and thermostats.
