So you need to trick them. Fake spring. If your home is hot, pop those seeds in the fridge for 24 hours before planting. Yes, your lettuce seeds are getting a spa day while you’re sweating. It’s humiliating, but it works.
Alternatively, do what I do: place your seed tray in the shadiest, draftiest corner of your apartment—like near the air conditioner vent. If you don’t have AC, freeze a water bottle and put it next to the pot. Desperate times call for desperate, slightly damp, refrigeration.
