Overview

The Aerobin composter is built for gardeners who want a reliable, high-performance composting system that works year-round. Designed with ease and results in mind, it uses advanced engineering to support healthy organic breakdown while integrating seamlessly into your garden routine.

At its core is a patented internal “lung” or aeration tube that draws in fresh air and releases warm gases naturally, promoting aerobic composting without the need to turn or mix the contents, and it doesn’t even need sun exposure.

Double-walled insulation in both side panels and lid keeps internal temperatures high even in cooler weather, accelerating decomposition and reducing odors. Finished compost is conveniently accessed via the lower side doors, and a built-in leachate tank with a hose and tap captures nutrient-rich compost “tea” for use as a plant fertilizer.

Because the Aerobin handles many of the key composting variables—airflow, temperature, moisture—it frees you up to focus on what matters: adding kitchen and garden waste and harvesting high-quality compost. Whether you’re supporting raised beds, vegetable plots, or container gardens, the Aerobin delivers dependable performance, helping you grow more productively and sustainably.

Frequently Asked Questions

Where is the Riga greenhouse made?

The Riga series of greenhouses is made by Hoklartherm in Apen, Germany. Hoklartherm has been manufacturing high quality greenhouses in Germany for over 40 years!

Can someone help me decide which greenhouse is best for me?

Our retailers are great resources to reach out to discuss greenhouses – and our Exaco customer service team is always ready to help your dream greenhouse come to life – we are just a call away. Over the years we have personally supported many customers choose their greenhouse and options – and that expericence goes a long way. You can also find additional resources and inspiration on our blog too.

Do I need a permit?

You might need a permit. Not everyone does and even sometimes those who do need a permit do not apply for one. Each municipality sets their guidelines for what types/size of buildings need a permit in their area – sometimes this is based on square footage or whether they consider it a “permanant structure” – but this is all decided by your local permit office. If you are applying for a permit, you should always go through this process BEFORE you order your greenhouse – depending on local wind/snow load requirements you may need additional reinforcements or supports to reach your local requirements. You may also find other restrictions for placement that may mean you have to limit the size or location. If you are going to get a permit, it is always best to know the restrictions ahead of time.

Do you provide structural certifications for the Riga/Riga XL greenhouses?

We have general structural certifications to give you a realistic idea of the loads of each greenhouse. However, if you are applying for a permit you may need a letter stamped by an engineer certified by your state, or you may need a site specific certification. We do not provide these state or site specific documents, but they are available for a fee. Conversely, we may be able to point you toward an engineer who can assist you with the documentation you need. Keep in mind, each location/state has different load requirements. If you are in a location that has higher load regulations, you may need to purchase additional reinforcements.

What is required to prepare the site for my polycarbonate greenhouse? Do I need concrete to anchor it?

The greenhouse site must be level, this will help ensure an easy and straightforward assembly. Your greenhouse must be anchored securely to the ground. This is best done in one of two ways. You may pour a concrete strip foundation (to the frostline is recommended by the manufacturer) or you may purchase a foudation/base frame kit for the greenhouse. The unique foundation frame eliminates the need for concrete. It hooks to the bottom of the greenhouse and is buried in a trench that is about 5″ deep all the way around the greenhouse. This will securely anchor the Riga greenhouse. Occassionally, we have also had people pour full concrete slabs and use anchor screws with the supplied L brackets – if you do this, please account for drainage. You can also find a wealth of information to prepare for your greenhouse in the first section of our assembly manual, which can be downloaded on the product page.
