A wise choice for garden enthusiasts looking for a durable and easy-to-assemble greenhouse kit to extend their growing season.

Buying Guide

When it comes to choosing the best greenhouse kit for your needs, there are several factors to consider. In this buying guide, we'll discuss some of the key features and factors to keep in mind as you make your decision.


Size and Space

One of the most important factors in choosing a greenhouse kit is the size and the space you have available. Carefully measure your intended greenhouse area and keep these dimensions in mind as you browse different options. Remember, you'll not only need space for the greenhouse itself, but also for walking paths, storage, and potentially work areas.


Frame Materials

Greenhouse kits come with a variety of frame materials, each with their own pros and cons. Some common frame materials include:


  • Aluminum: Lightweight and durable, aluminum frames are a popular choice. They are resistant to rust and can be relatively easy to assemble.
  • Wood: Wooden frames offer a more traditional look and can be quite sturdy. However, they may require more maintenance and are typically heavier than aluminum frames.

Glazing Options

The type of glazing you choose for your greenhouse can impact its energy efficiency and the overall growth conditions for your plants. Some common glazing options include:


  • Glass: Traditional glass panes provide excellent light transmission and are visually appealing, but they can be fragile and may require more maintenance.
  • Polycarbonate: This durable and lightweight plastic material is becoming an increasingly popular choice for greenhouses. It offers good light transmission and insulation properties while being much more resistant to breakage compared to glass.

Ventilation and Temperature Control

Proper ventilation is essential to maintaining a healthy growing environment inside your greenhouse. Look for greenhouse kits with built-in vents, or consider adding a ventilation system separately. Automated temperature control systems can also help you maintain optimal growing conditions, but may come at an additional cost.


With these factors in mind, you should be well-equipped to make an informed decision on the best greenhouse kit for your specific needs. Keep in mind the space, frame materials, glazing, and ventilation options when selecting a kit, and you'll be on your way to creating a thriving, successful greenhouse.
