Topping and Fimming

In this episode of Hydroponics Daily, Dr. Russell Sharp invites Matthew Wallace to discuss the intricate techniques of topping and fimming plants. Discover how these methods can significantly impact plant growth and yield, and learn about the essential differences between the two.
Matthew explains the process of topping, which involves cutting the fresh growth at the top of the plant to encourage more branching and increase the number of flowering sites, ultimately enhancing fruit production. They also delve into the technique of fimming, which, unlike topping, involves a partial cut, promoting a bushier plant structure.
The episode offers insights into situations where these techniques should be avoided, such as with autoflowering strains. Join the conversation as Matthew provides expert advice on maximizing plant growth and yield through careful application of these advanced horticultural practices.

Foliar Sprays - hype or hack?

Welcome back to another insightful episode of Hydroponics Daily! Today, we delve into the world of foliar sprays, exploring both their benefits and disadvantages. As a manufacturer of foliar sprays, we have first-hand knowledge to share. Foliar sprays are an excellent way to deliver biostimulants, micronutrients, and even correct soil imbalances in plants. However, their application can also lead to increased humidity and potential leaf scorch.Learn how foliar sprays can be both beneficial and problematic, and how to avoid common pitfalls. We also provide tips on making informed purchasing decisions to ensure you're not overpaying for diluted products. Tune in for a balanced discussion on the role of foliar sprays in hydroponic gardening.

Integrated Pest Management in Hydroponics

Welcome to another insightful episode of Hydroponics Daily with your host, Dr. Russell Sharp, known for inventing liquid gold in the UK. In this episode, we dive into the world of Integrated Pest Management (IPM), an essential approach to maintaining healthy plants. Unlike the conventional divide between chemical and organic farming, IPM leverages diverse techniques to minimize pesticide use, promoting sustainable practices even in organic setups. Learn how location, crop selection, intercropping, and biological controls can effectively manage pests and diseases, keeping your hydroponics thriving. Dive in to explore revolutionary methods that go beyond harmful chemical dependencies, ensuring a balanced and productive growing environment.

Extracting gold from plants

In this intriguing episode of Hydroponics Daily, Dr. Russell Sharp delves into the remarkable story of Fritz Haber, the man behind the Haber-Bosch process.
