Step 1: Choose the Right Container Successful seed starting begins before a seed ever touches soil with the right container. Your choice should match your available space, the type of plants you’re growing, and your experience level. Small seeds benefit from shallow trays or pellets, while larger seeds may need deeper cells. Jiffy® seed-starting products simplify this decision with biodegradable pots, expandable pellets, sturdy trays, and complete greenhouse kits. These systems provide excellent drainage, consistent moisture, and proper air flow which are key factors for healthy root development. Domes and greenhouse covers increase humidity, which enhances the seedling success. Starting with the right container reduces transplant shock and sets seedlings up for strong, confident growth from day one.
