This video shows how to grow lettuce in glass mason jars hydroponically, meaning in water instead of in soil. I use the Kratky method, which does not need an air pump. A simple glass jar is good enough to grow the lettuce as you will see. The seeds sprout very quickly, and in just 5 weeks I have a beautiful harvest! After another 2 weeks the leaves to grow back and I am able to harvest a second time! Very delicious both times!

    Can I keep in the inside kitchen window instead of using lights? Plenty of sunlight penetrates inside.

    Alternatively, you could use the wide mouth pint jars instead of the standard mouth pints. The wide mouth pints have the same mouth size as the quarts.

    Tikki O… that is a very good way to start your seeds.. simply put them in the cubes..keep them All moist in a shallow container till you have them germinated, and you just start to see seed coming out the cube..and you've chosen the one you're likely to have success with , then move the cube to their "hydroponic jar". ..This is much more efficient.

    Hi. I got mixed up with Day 14 in timeline at 3:43 and Day 12 timeline at 16:13.
    I presumed the Day 14 is the 10th day if I got it right.

    Also, are the big ones 12 ounce mason jars?

    Very informative video. I am just starting germinating seeds the way you showed it here. Thank you. Shalom

    I have to try another Kratky method. The 'clay pellets in a basket' was a disaster for me. My babies got brown and died.
