Plant growth

Today more than half of the world’s population lives in cities and relies on food shipped over long distances. This inefficiency could be resolved by growing food locally.

Urban greenhouses

CO2 is an essential building block in the photosynthetic growth of trees, plants and flowers. The global human population is projected to surpass 9 billion by 2050. At the same time, humanity is also facing many challenges when it comes to food production, such as climate change, severe droughts, soil depletion, diseases, water pollution, water scarcity, and the loss of biodiversity.

Urban greenhouses provide an optimal solution for feeding the growing urban population. And CO2 has an important role to play here. It is an essential component of photosynthesis, a chemical process that uses light energy to convert CO2 and water into sugars in green plants. The plants then use these sugars to grow. A higher level of CO2 can speed up this process and enable healthier, stronger plants. Depending on the crop, this can lead to an increase in yields of 20% to 40%.

Our technology gives the end user access to a convenient, independent supply of CO2 that is easy to use and maintain. Skytree is currently working with a US based urban greenhouse developer to make this process a reality.


Aquarium market: ‘Helping plants grow in water’

Aquarium-keeping is the second biggest hobby on this planet. Much as with trees and plants on land, CO2 can also make aquatic plants greener and stronger. It has the added benefit of stabilizing the pH level of the water, and even reducing algae problems. In Europe alone, more than 15 million people own an aquarium. Approximately 90% of these are fresh-water aquaria which could benefit from a higher level of CO2.

Skytree is working closely with Eheim, a world-leading manufacturer of aquariums and related equipment, to develop a novel CO2 supply unit for the aquarium market. This product is a revolutionary addition to Eheim’s already impressive range of products.

Our new product is on the forefront of one of the most important trends in the worldwide aquarium market: aquascaping. This craft can best be described as underwater gardening, and CO2 plays a vital role in it. One of the world’s most respected experts in aquascaping is Oliver Knott. As an expert, Oliver understands as no other the potential impact of our technology for this sector, which is why he fully supports our project.

The Stingray

Our product represents the only fully automated solution on the market. The CO2 dose can be easily adjusted to the specific need of each aquarium, so that instead of buying or refilling CO2 cartridges, customers have access to a continuous supply of ‘atmospheric’ CO2 from the ambient air.

Linked to a power source, the ‘Stingray’ will deliver the required amount of CO2 for many years. Stylish, cheap, safe and easy to use.
