Article V explains the amendment process, which is different and more difficult than the process for making laws. When two-thirds of the Senate and two-thirds of the House of Representatives vote to change the Constitution, an amendment goes to the state legislatures for a vote.
Another way to use the fridge for brief cold stratification is to plant the seeds in individual jiffy pellets and put them in either a plastic covered container (such as for home baking little bread loaves) or in a store-bought greenhouse flat. Depends on how much room you have in your fridge.
Harden seedlings by reducing water and temperature for 3 days before transplanting. Hardened plants should survive 20 F. Space crisphead transplants 12 inches apart in rows 18 inches apart. Space other varieties 6 to 10 inches apart in rows 12 to 18 inches apart. Seeds need light to germinate, so do not plant too deep.
