Best Indoor Greenhouse Buyers Guide

With hundreds of brands and portable greenhouse products available in the market, it might be a bit hard to choose the best indoor greenhouse for your home.

There are certain key features, factors, and parameters that every potential buyer must consider before making a final choice. In this buyer’s guide section, we will discuss some important factors to consider before choosing one particular indoor greenhouse over another.

Adequate Ventilation

The main cause of plant death and damage in a greenhouse is overheating.

Before buying an indoor greenhouse, make sure that it can retain warm air during winter months and release hot air during hot and humid seasons. 

Always give consideration to the airflow; it must have ample allowance for air to exit and enter the unit. 

Choose a greenhouse with vents near the top and base for air flow.  Many greenhouses available today also feature exhaust fans to avoid overheating during summers. If which ever greenhouse you choose does not come with a built in exhaust fan, you can simply add a small fan facing outward into the greenhouse vent. This is an easy way to draw the overheated air out of the greenhouse and help maintain an optimal environment for your plants.

Proper Insulation

The current climate within your gardening region directs the amount of insulation needed for the indoor greenhouse.  

A high-quality greenhouse covering must be able to retain the heat within the unit and keep it warm so you can heat up to the potted plants without wasting more money.

Apart from the covering materials, a variety of insulating schemes are also accessible, so you can take measures depending on the requirements of your growing season. You can insulate the walls, roof, and foundations of the greenhouse or use a simple UV stabilized polyethylene bubble wrap to achieve the purpose.


The greenhouse frames are accessible in a wide range of materials. Aluminum delivers a strong yet lightweight, rust-free frame. Aluminum frames have a long life span and can provide a perfect fit for the covering panels. 

Tubular steel frames are extremely robust and long-lasting. Thanks to the inherent strength, the greenhouse needs minimal structure for framing resulting in more light coming through for the plants.

Plastic frames are also famous for their attractive look and cheap cost. Wood frames are also used by DIY gardeners as they have an aesthetic appeal and durability to them.
