How do you germinate onions quickly?
Provide bottom heat
The tops of my florescent plant lights are flat, and they give off just the right amount of bottom heat needed to help onion seeds germinate quickly. Onion germination is fastest as 68-77°F (20-25°C), with slight temperature drops at night.
Why soak onions in ice water before making onion rings?
Soak the onion slices in cold water to dilute the sulfur content, turning them sweet and mild. For a crust that stays crisp and has character, double dip the rings in buttermilk and seasoned flour.
How do you soak onion sets in water?

Sets are dormant bulbs that can be planted directly into the ground. Onion sets should be planted 1 to 2 inches deep and 2 to 3 inches apart. Then, once the plants begin to grow, thin them to 3 to 4 inches apart. Plants thinned from the row to create room can be used as green onions.
