In this episode of Hydroponics Daily, we dive into the common misconception that placing crocks (pieces of broken pot or stones) at the bottom of containers helps improve drainage. We explore why this practice, often passed down through generations or learned from magazines, may actually impede proper water flow.
Through a simple experiment analogy with a sponge, we reveal how such practices can create more harm than good, leading to water retention rather than drainage. The episode highlights the importance of using rose pots, known for their upright and effective drainage design, offering an alternative to the widespread use of crocks.
Join us in uncovering the truth about this bro-science myth and learn better techniques to ensure your plants thrive, while encouraging listeners to stay tuned for more horticultural insights.
