Growing Joy with Plants - Wellness Rooted in Nature, Houseplants, Gardening and Plant Care Leca vs Pon: Which Is Better for Indoor Plants? Best of Growing Joy Replay
What if you could grow 300+ indoor plants without hauling watering cans to the shower every weekend… and without even dealing with soil?
In this episode of the Best of Growing Joy series, we’re revisiting one of the most amazing approaches to plant care: passive hydroponics, often called semi-hydro. My friend Kay from @inrootedlove is back for what we’re calling Passive Hydro 2.0, and we’re diving into the real-life details of growing plants this way. We talk about LECA vs Pon, root pruning, reservoirs, fertilizer concerns, and what happens when life gets busy and you forget about your plants for a while.
If you’ve experimented with LECA, are curious about Pon, or want to better understand passive hydroponics for indoor plants, Kay is the perfect person to learn from. This conversation will help you troubleshoot common issues, understand the method more deeply, and grow your plants with greater confidence.
