Understanding the Properties of Hemp and Jute Mats
Hemp and Jute are popular natural fibers that make up the outer coating for the stems of their respective plants. They are stripped from the stems in a retting process to obtain the fibers. Due to the robust nature of hemp fibers, they are known for their exceptional durability and strength. The word “canvas” shares the letters “Can” from cannabis. Cannabis/hemp fibers were used for canvas ship sails and rope.
In contrast, Jute fibers are softer, supple, and more pliable. They are also highly absorbent, making them ideal for our purpose, which is growing microgreens. Jute's long fibers have a golden silky shine; as such, it’s nicknamed “the golden fiber.” Jute's softness allows it to blend well with other fibers for many applications. During the Industrial Revolution, Jute replaced hemp fiber in many textile applications.
Regarding sustainability, both hemp and jute are renewable and biodegradable resources, making them environmentally friendly choices. Growing both Jute and hemp consumes tons of carbon from our air and releases tons of oxygen, having a climate-mitigating effect on our planet.
The choice between hemp and jute fibers will depend on the user's specific needs and purpose. Hemp mats are typically used for high-performance applications, such as strength and durability in harsh conditions. Jute mats offer a softer, more pliable, and absorbent solution. This can be a benefit when the materials must be manipulated differently. The absorbent quality of jute is ideal for growing microgreens. Regardless of the selection, natural fiber mats provide a sustainable and biodegradable alternative to synthetic options that will remain in landfills for decades.
The Impact of Mat Material on Plant Growth and Development
When cultivating healthy, thriving plants, the choice of medium to grow in can significantly impact growth and development. Physical properties can affect major factors like water retention. Chemical properties can affect pH and cation exchange, facilitating the plants’ ability to uptake water and nutrients. Choosing the right mat for your microgreen production can make all the difference as you optimize growing conditions at home or in a professional facility.
One key factor is the mat's ability to provide adequate drainage. Poorly draining mats can lead to a waterlogged rootzone, depriving plant roots of essential oxygen and potentially fostering the growth of harmful fungi or bacteria. Conversely, highly porous mats that allow for rapid drainage may result in soil that dries out too quickly or unevenly. This can lead to uneven growth or stressed and stunted plants.
The mat material's water-holding capacity is also crucial. Mats that retain moisture well can help maintain a consistent supply of hydration. By avoiding drought and flood events, you can guarantee your plants have the steady supply of the water and nutrients they need to thrive. However, overly absorbent mats can also create problems, creating a breeding ground for anaerobic bacteria and increasing the potential for root rot.
By choosing a mat that creates a healthy interaction with the plant's roots, a grower can begin to tailor the growing environment to the specific needs of the cultivated plants, considering factors such as temperature, humidity, air velocity, and desired yields. By carefully selecting the right mat, growers can create an optimal environment, both atmospheric and rootzone, that maximizes the potential for healthy, vibrant plant growth and development.
Hemp or Jute, Which is The Better Choice?
Hemp: The Versatile Wonder
Hemp is a remarkably versatile fiber with an impressive array of applications. This resilient plant can meet various demands, from textiles and clothing to building materials and bioplastics. Microgreens are a crop with a short life cycle. From germination to harvest is typically 14 days or less. While hemp mats are rugged and durable, that level of strength is not a factor in microgreen production. Hemp fibers are not inherently absorbent, which is a factor when considering the needs of a microgreen producer. In this scenario, the term that comes to mind is “overbuild,” when a component's strength exceeds a product's needs.
Jute: The Underrated Powerhouse
Often overshadowed by its hemp counterpart, Jute deserves its moment in the spotlight. This natural fiber, derived from the Corchorus plant, offers exceptional biodegradability and a lower environmental impact. Jute fiber is not only affordable but considered second only to cotton in worldwide production and a variety of applications. We have found that microgreens grow exceptionally well on our jute-based ReNu Terra mats. Jute's inherent absorption and breathability make it an ideal medium for microgreen cultivation.
The Sustainable Showdown
Regarding sustainability, both hemp and jute stand out as eco-friendly options. They are both biodegradable and a valuable crop for sequestering carbon. However, the scales may tip in favor of Jute due to a few factors. It is typically rain-irrigated and requires little to no pesticides. Additionally, the retting of jute fibers is mainly done with biological processes without chemicals. Rotating crops with jute production adds to the soil fertility of the next crop.
Unlocking the Full Potential of Your Garden with the Right Microgreen Mat
Microgreen mats are a game-changer for indoor farms. Creating a healthy balance of water and oxygen for your root zone allows indoor microgreen farmers to maximize productivity in their growing environment. In turn, time savings in the form of faster crop cycles become revenue-generating produce supplied to consumers.
Let your choice of microgreen mat reflect the care and effort you put into every aspect of your cultivation practice. While we hope you consider trying our ReNu Terra mat for your microgreen production, we hope this discourse helps our indoor farming community grow a more sustainable future. Whether you choose hemp mats or our ReNu Terra jute-based mats, we are excited to see more plants grown to their full potential, feeding healthier people and creating a healthier planet.
