Seed Starting Supplies FAQ
What supplies do I need to start seeds?
Core seed-starting supplies include trays and cells, a seed-starting mix, labels, and a way to provide warmth and light. A fine, sterile starting mix and clean trays give seedlings the best start. The specific setup depends on scale, but consistent moisture, warmth, and light are what germinating seeds need, supported by the right containers and media.
What is the difference between seed-starting mix and potting soil?
Seed-starting mix is a fine, light, sterile medium that holds moisture and lets delicate roots and sprouts develop without the heavier texture, larger particles, or potential pathogens of regular potting soil. Starting seeds in a proper seed-starting mix improves germination and reduces damping-off disease, which is why growers use a dedicated mix rather than garden soil or heavy potting mix.
Why is bottom heat used for seed starting?
Bottom heat (heat mats) warms the root zone to the temperatures many seeds need for fast, even germination, since cool media slows or prevents sprouting for warm-season crops. Consistent warmth from below speeds germination significantly. For starting heat-loving seeds early, bottom heat is often the difference between reliable germination and slow, patchy results.
How much light do seedlings need?
Seedlings need strong, consistent light once they emerge, or they stretch and grow weak and leggy reaching for it. A bright location or supplemental grow lights kept close to the seedlings produces stocky, healthy transplants. Insufficient light is the most common reason home and small-scale seed starting produces weak seedlings, so adequate light is essential after germination.
How do I prevent damping-off in seedlings?
Damping-off, a fungal disease that kills seedlings at the soil line, is prevented with clean trays, sterile seed-starting mix, good air circulation, and not overwatering. Wet, stagnant conditions invite it. Using sanitized containers and a sterile mix, watering carefully, and providing airflow are the practices that keep seedlings from succumbing to this common propagation problem.
Can seed-starting supplies be ordered in bulk?
Yes. Seed-starting trays, mix, heat mats, and supplies are stocked in quantities for production growing with volume pricing by quote. Operations starting seeds at scale benefit from ordering trays, media, and supplies in volume ahead of the season, since seed starting is a high-volume activity at the start of the growing cycle.
