This last winter as I longed for Spring, a magazine showed up in our mail box with the story of an elderly man who started growing lettuce in mason jars using the Kratky method during Covid.  He had videos online and gave out a list of all the items needed to begin growing lettuce in your own home.  You need a mason jar, a net pot, growing medium (like rockwool), hydroponic nutrients, seeds, a light source and a timer.  Fill the jar with the water and nutrients, plant the seeds in the rockwool and place in net cup in the top of the jar and add light.  Cover the jar with a black sock to block light which prevents algae.  Or purchase amber mason jars. 

That’s about all there is to it and you can grow your own delicious salad every day and in every season. 

Jerry(the man whose videos I followed), suggested to start with butter crunch lettuce seeds.  I have also grown, per his suggestion, merlot and outredgeous lettuce.  Both of these lettuces are not only tasty but they are beautiful.  You can find many videos on everything needed and instructions to grow lettuce.

Now sit back and enjoy your delicious salad.
