Observations of Pepper Seedling Development in Stabilized Plugs, not Standard Loose Rooting Medium

By Matthew Kleinhenz

On a March 1, 2025 in this blog, we summarized our initial impressions of pepper seedling development in stabilized plugs instead of a standard loose medium and explained that our upcoming use of stabilized plugs was prompted by collaboration with researchers at UC-Davis and The OSU in which we are working to better understand and breed for yield under water and heat stress in bell pepper. Here, we provide a brief update on seedling development in stabilized plugs provided by https://ihort.com/q-plug/. Images below collected 3/22/25 reinforce the idea that seedlings produced in the plugs may be uniform, straightforward to irrigate, easy to handle, and field-ready sooner after seeding (requiring less time in the greenhouse and adding flexibility to seeding schedules). Additional tests are required to verify these preliminary, early-stage speculations. These and other stabilized plugs can be used with seed (varying in size) and cuttings.
