Controlled environment agriculture (CEA) is revolutionizing the way we grow food, cannabis, and a variety of other crops. It offers a high-tech solution to many of the challenges faced by traditional farming methods.

As we look towards a future with an ever-increasing global population and unpredictable climate patterns, CEA presents an innovative approach to ensure food security and sustainability.

What is Controlled Environment Agriculture?

Controlled environment agriculture represents a paradigm shift in modern farming practices that not only solves problems of traditional farming but also takes indoor growing to the next level of technological advancement. It’s a method of crop production that takes place in enclosed structures that are sealed off from the outside environment.

In a CEA system, every aspect of the plant's environment is carefully managed throughout all growing stages, including:

Water supply
Temperature regulation
Humidity levels
Ventilation systems
Light intensity, spectrum, and length of exposure
CO2 concentration
Nutrients and feeding

A typical CEA facility is a sophisticated operation of agricultural technology and expertise depending on the growing techniques used. These methods enable farmers to create optimal growing conditions for specific crops, needs, and desired outcomes. As a result, they can achieve higher yields, consistent quality, and reduce resource consumption compared to traditional agriculture.

The core principle of a CEA system is the precise control of environmental variables to optimize plant growth and yield. By removing the unpredictability of outdoor farming, CEA allows for unprecedented levels of control over crop production, opening up new possibilities for sustainable and efficient agriculture.

Sustainable Fashion Industry

Some innovative fashion brands are exploring CEA to grow textile crops like cotton in more sustainable ways. By controlling the growing environment, they aim to reduce water usage and chemical inputs while improving fiber quality and consistency.

Benefits of Using bio365 Growing Media in CEA

One of the biggest disadvantages of CEA is that nature is removed from the growing process. The problem is plants need nature to thrive – it’s in their DNA! They need the biology in soil to reach their full potential.

The truth is there is good biology and bad biology in soil. Before bio365 invented its 100% clean, biologically-active growing media, there was no way to safely bring beneficial biology to plants in CEA facilities. That’s not the case anymore.

With bio365, plants in CEA environments get the wide-spectrum beneficial biology they need to thrive because we invented a growing media using patented processes that bio-mimic all of the “good stuff” plants get from soil in nature without any of the “bad stuff”.

Here are just some of the benefits that bio365 growing media brings to plants in CEA:

Developed for CEA to Eliminate Risk

All bio365 growing media products are designed from the ground up to be used in controlled environment agriculture. We culture our biology using our patented and 100% proprietary process that guarantees consistency.

We also engineer, manufacture, and store our products 100% indoors in controlled conditions to ensure it’s 100% clean and consistent for controlled environment agriculture use, which means there is no risk to using it in a CEA facility – only benefits!

100% Clean, Wide-Spectrum, Beneficial Biology Plants Need

At bio365, we start with the carefully-selected ingredients that go into making our soil, and then, we use a patented process to biotransform those ingredients – taking out all of the bad and leaving all of the good.

What comes out of the process is a growing media that mimics nature and gives plants the wide-spectrum beneficial biology they need but can’t get from any other 100% clean, living media.

On-Demand Nutrient Delivery for Resilient, High-Quality Plants

One of our “secret sauces” is bioCHARGE®, which is our multi-patented, activated, and aged combination of clean, beneficial, wide-spectrum microbiology anchored by our high temperature, high-carbon bioCORE® biochar matrix. bioCHARGE also has bioavailable nutrients and is what enables growers to deploy beneficial microbiology in controlled environments.

It’s bioCHARGE that allows plants grown in controlled environments to signal the clean microbiology in bio365’s growing media whenever they need nutrients, water, or assistance battling pests and pathogens. It maximizes efficient on-demand delivery of water and nutrition to plants, which increases plant health, quality, resiliency, and yields.

Optimized Water Accessibility and Aeration for Bigger Roots & Yields

All bio365 growing media have macro-pores, micro-pores, and nano-pores. This third level of nano-pore space is part of our patented bioCORE biochar technology that opens a microscopic level of pores for plants.

As a result, bio365 not only has class-leading water retention but also, plants can consistently access more air and develop bigger and better root structures that lead to larger crop yields.

Pest and Pathogen Resistance for Healthier Plants

Wide-spectrum biology in soil is a plant’s immune system in nature. When you remove the beneficial biology from your growing media, you remove your plants’ immune system! As a result, it instantly becomes infinitely harder for your plants to protect themselves against pests and pathogens.

The millions of beneficial microbes in bio365 growing media mimic the immune systems that plants’ get from soil in nature allowing growers who use it to improve plant health and boost crop yield in controlled environments.

Consistency Leads to Better, Reliable Outcomes and Lower Costs

Using our patented culturing process, bio365 makes our own wide spectrum biology that is 100% consistent from batch to batch and bag to bag. We culture from the same mother batch generation after generation and test it every time. Every bio365 product is made on computer-controlled mix lines to standardized recipes then packaged on carefully calibrated equipment before being palletized by a robot.

We follow a 41-step quality process that ensures the quality of our soil is consistent from one bag to another, one batch to the next, one palette to the next, and so on. This precise level of consistency ensures growers get reliable outcomes. Once dialed into the media, they can significantly reduce costs on inputs, labor, and more.
