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.
