Battling Heat Stress in Hydroponics

In this episode of Hydroponics Daily, we delve into the pressing issue of heat stress as the UK experiences unseasonably warm and dry weather, with similar conditions affecting other regions as we approach summer. We explore why starting hydroponics in the winter is more advantageous, as summer poses challenges with increased environmental control needs, particularly heat stress.
We discuss optimal temperature ranges for most plants and what happens when temperatures exceed these ranges. Learn about the detrimental effects on plant health, including scorched leaves, malfunctioned fruits, and halted photosynthesis. We also offer essential advice on maintaining hydration levels and preventing water deficits in your hydroponic systems.
Discover methods to mitigate heat stress, such as adjusting light intensity, managing CO2 enrichment, and boosting air circulation and humidity levels. We also highlight the potential value of installing air conditioning units for medium to large-scale growers, and the role of certain biostimulants in heat stress resistance.
Tune in for practical insights and strategies to protect your crops and ensure a bountiful harvest despite high temperatures. Share your experiences or suggestions if we've missed any critical heat management tips. Thank you for listening to Hydroponics Daily!

Clover Mites: ever heard of them? You've certainly seen them!

Welcome back to Hydroponics Daily, where today’s episode dives into the world of clover mites. These bright red mites are often mistaken for the more problematic red spider mites, but they belong to an entirely different species. While clover mites are usually seen on lawns, walls, and stones, red spider mites are a known pest for crops, particularly in greenhouse and indoor hydroponic settings.
Despite their appearance, clover mites pose no significant threat to plants and generally stay outdoors, rarely causing indoor infestations. Host [Name] explains how these harmless mites are often wrongly feared and discusses why there's no need to eliminate them unless they're causing real problems. Tune in to discover the difference between these two mites and learn why embracing nature’s diversity is the best approach.
