Iron in Hydroponics

Thursday Jan 23, 2025

Thursday Jan 23, 2025

In this episode of Hydroponic Daily, Dr. Russell Sharp, the inventor of Gold Leaf, dives deep into the significance of iron, or FE, in plant health. Although a micronutrient, iron is vital because it is a core component of the chlorophyll molecule, essential for photosynthesis. Dr. Sharp explains how iron deficiency leads to chlorosis or yellowing of young leaves, especially in alkaline soils.
He highlights the role of chelated iron in preventing deficiency and its common use in treating citrus crops and lawns. Iron's instant greening effect on turfgrass is noted, though it's also pointed out that this is not due directly to chlorophyll production. Additionally, Dr. Sharp emphasizes the importance of iron in the flowering phase of high-value crops, explaining how increased iron contributes to greater weight and density.
Discover why iron is often overlooked in hydroponics and learn about innovative iron products that can enhance your growing results. Whether you're an advanced grower or just starting out, this episode provides valuable insights into maximizing yield with the right iron balance.

Calcium in Hydroponics

Wednesday Jan 22, 2025

Wednesday Jan 22, 2025

In this insightful episode of Hydroponics Daily, host Russell Sharp delves into the crucial role of calcium in plant nutrition, particularly within hydroponic systems. As a secondary macronutrient, calcium is vital for the strength and growth of plant cell walls and is an essential player in cell division and signaling.
Russell outlines the common problem of calcium deficiency, which often manifests as necrotic tissue in young plants, leading to issues such as "dead heart" in lettuce and blossom end rot in tomatoes. Despite appearances, these problems are typically caused not by a lack of calcium but by inconsistent water availability and environmental factors.
Listeners will gain insights into maintaining calcium levels and learn the art of balancing water management to prevent deficiencies. Russell debunks common misconceptions related to one-part fertilizers and highlights the importance of selecting the right nutrients to ensure healthy, thriving plants in any hydroponic setup.

Magnesium in Hydroponics

Tuesday Jan 21, 2025

Tuesday Jan 21, 2025

In this episode of Hydroponics Daily, Dr. Russell Sharp, inventor of Gold Leaf, delves into the integral role that magnesium plays in the photosynthesis process. As the central atom in the chlorophyll molecule, magnesium is crucial for the absorption and transfer of energy. Dr. Sharp explains what happens when there is a deficiency, characterized by interveinal chlorosis, and how it impacts plant health and yield.
The episode provides insights into the causes of magnesium deficiency, particularly in hydroponic systems, where excess calcium or potassium can interfere with magnesium uptake. Practical solutions such as using dolomitic lime and Epsom salts are discussed to ensure a balanced nutrient supply. Furthermore, the discussion highlights the importance of calcium and magnesium supplements, like calmag, as essential tools in maintaining crop quality.
Join Dr. Sharp as he shares his expertise on preventing nutrient imbalances, ensuring you have the best practices in place for successful plant growth and health.
