The Power of NADH and NAD+ in Plant Health

Authored by:

Anthony Robison

When it comes to plant health and growth, two essential molecules often fly under the radar: NADH (Nicotinamide adenine dinucleotide in its reduced form) and NAD+ (the oxidized form). These coenzymes play crucial roles in how plants function, helping them convert food into energy and manage various processes that are vital for their survival.

Energy Production: Fueling Growth

NADH and NAD+ are key players in cellular respiration, the process by which plants generate energy. NAD+ acts as an electron acceptor during crucial steps like glycolysis and the Krebs cycle. When it takes on electrons, it becomes NADH. This transformation is essential for producing ATP, the energy currency that powers all of a plant's activities. Without sufficient energy, plants cannot grow or thrive.

Metabolic Reactions: Building Blocks of Life

These coenzymes are involved in numerous metabolic pathways that help plants synthesize vital compounds, such as sugars and amino acids. By participating in these reactions, NADH and NAD+ ensure that plants have the necessary building blocks for growth, development, and overall health.

Stress Response: Protecting Against Damage

Plants face a variety of environmental stressors, such as drought and extreme temperatures. NADH and NAD+ play a significant role in how plants respond to these challenges. They help regenerate antioxidants, which protect plant cells from damage caused by harmful molecules known as reactive oxygen species (ROS). This protective mechanism is crucial for maintaining plant health during stressful conditions.

Cell Growth and Division: Regulating Development

One of the fascinating roles of NAD+ is its involvement in the cell cycle. It helps regulate when and how cells divide, which is essential for plant growth. By ensuring that new cells are produced, NAD+ supports the development of roots, shoots, and leaves, enabling the plant to expand and thrive.

Signaling Molecules: Communication Within the Plant

Beyond their roles as coenzymes, NAD+ also functions as a signaling molecule. It helps plants communicate and respond to changes in their environment. This ability to signal and adapt is vital for healthy growth and survival, allowing plants to optimize their functions in varying conditions.

Soil Microbial Interactions: Supporting Soil Health

Healthy plants don’t exist in isolation; they rely on their relationship with the soil and its microorganisms. NADH and NAD+ can influence beneficial microbes in the soil, enhancing plants’ ability to absorb nutrients. A thriving soil ecosystem leads to healthier plants, showcasing the interconnectedness of plant health and soil quality.

Conclusion: The Importance of NADH and NAD+

NADH and NAD+ are vital for plant health and growth. They help produce energy, support metabolic processes, protect against stress, regulate cell growth, facilitate communication within the plant, and promote healthy interactions with soil microbes. By maintaining optimal levels of these coenzymes, plants can become stronger and more resilient, ultimately leading to a flourishing garden or landscape.

When to Harvest Organic Cannabis: Trichomes vs. Senescence

Authored by: Anthony Robison Harvesting cannabis at the right time is crucial for maximizing potency, flavor, and overall quality. When growing organically, some growers wonder whether they should wait for natural senescence (the plant’s natural fading process) or rely on trichome development to determine the best harvest time. The short answer? Trichome maturity should be your primary guide, while senescence can be a secondary indicator. Here’s why. Trichomes: The Most Reliable Harvest Indicator Trichomes are the tiny, crystal-like resin glands on cannabis flowers that contain cannabinoids and terpenes. By monitoring their color and maturity, you can pinpoint the ideal harvest window. Trichome Color Guide for Harvesting: Clear Trichomes “ Too early; cannabinoids are still developing. Cloudy (Milky) Trichomes “ Peak THC potency; best for strong, euphoric effects. Amber Trichomes “THC is degrading into CBN, leading to more sedative effects. For most growers, the sweet spot is when most ...

Boosting Trichome & Resin Production in Cannabis with Chitin

Authored by: Anthony Robison Cannabis cultivators are always looking for ways to enhance trichome density and resin production. One of the most effective but often overlooked methods is using chitin, a natural compound that can significantly boost cannabinoid and terpene output. But how does it work, and how can growers use it effectively? Let’s dive in. What Is Chitin? Chitin is a naturally occurring biopolymer found in the exoskeletons of insects, crustaceans (like crabs and shrimp), and the cell walls of fungi. When introduced to cannabis plants, chitin triggers natural defense mechanisms, leading to increased trichome production and resin content. How Chitin Enhances Trichome & Resin Production 1. Activates the Plant’s Defense Response Cannabis plants rely on trichomes to protect themselves from pests, UV radiation, and environmental stressors. When the plant detects chitin, it interprets it as a sign of insect or fungal attack, triggering: Systemic Acquired Resistance (SAR): ...

How Senescence Affects Cannabis Flavor

Authored by: Anthony Robison One of the biggest questions for organic cannabis growers is whether to wait for natural senescence before harvesting or cut the plant down while it’s still green. Timing your harvest correctly can make a huge difference in flavor, smoothness, and overall quality. But does harvesting before senescence lead to a more grassy taste? And can allowing senescence to occur help cannabis release chlorophyll quicker during drying? Does Harvesting Before Senescence Lead to a Grassy-Tasting Product? Yes, harvesting before senescence can result in buds that taste more “grassy” or “hay-like” this is because the plant still contains high levels of chlorophyll and nitrogen-based compounds, which contribute to the fresh-cut grass aroma and harsher smoke. Why Early Harvesting Affects Flavor: 1. Higher Chlorophyll Content “ Young, green plant material holds more chlorophyll, making the smoke harsher and less flavorful. 2. Slower Chlorophyll Breakdown “ If too much chlorophyl...
