Seed Starting & Indoor Grow Buying Guide
π‘ Light Distance
Keep grow lights 2-4 inches above seedlings. Too far = leggy, weak plants. Too close = leaf burn. Adjust daily as seedlings grow.
π Timing
Start seeds 6-8 weeks before your last frost date. Use your USDA zone to calculate. Starting too early creates rootbound, stressed transplants.
