Common Questions
What supplies do I need to start seeds indoors?
A basic setup includes seed-starting mix or plugs, a tray, inserts or cells, a humidity dome, labels, light, and a heat mat for warm-season crops.
Do seeds need a humidity dome?
A humidity dome helps keep moisture stable during germination, but it should be vented or removed after seedlings emerge to prevent disease.
When should seedlings move out of the tray?
Transplant when roots hold the plug together and seedlings have enough true leaves. Timing depends on crop, tray size, and growing conditions.
