The above propagation data sourced from Claude AI

Pre-treatment: Seeds were sown into cone-tainers filled with Sunshine #1(a soil-less peat-based media) amended with micro-nutrients (Micromax) and a slow release fertilizer (Osmocote 14-14-14). The flats of cone-tainers were covered with poly-ethylene bags and placed in a walk-in cooler for 90 days.
