Description: I’m trying to find things to do with the kidlets during time off school and this seems like something that is not only educational, but useful! This is a simple and easy to set up. It’s a hands-off approach to Hydroponics, and it works well for growing leafy greens. This method will take about 45 days to produce healthy, clean, and blemish-free leafy greens of your choice! I have successfully grown several varieties of lettuce using the following method.

READY IN: 45 days

INGREDIENTS

One or more quart-sized wide-mouth canning jars with bands (or any glass jar)

3-inch (7.6 cm.) net pots – one for each mason jar

Rockwool growing cubes for starting the plants

Hydroton clay pebbles

Hydroponic nutrients

Herb or lettuce seeds (or other desired plant)

DIRECTIONS

Block light from entering the mason jar in order to prevent algae growth. You can coat the jars with black spray paint, cover them with duct or washi tape or use a light-blocking fabric sleeve. The latter allows you to easily view the root systems of your hydroponic mason jar garden and determine when to add more water.

Plant the seeds in the rockwool growing cubes. While they are germinating, you can prepare the mason jars. Once the seedlings have roots extending out of the bottom of the cube, it’s time to plant your hydroponic garden in glass jars. Wash the mason jars and rinse the hydroton pebbles. Prepare the mason jar by spray painting it black, coating it with tape or enclosing it in a fabric sleeve. Place the net pot in the jar. Screw the band onto the jar to hold the net pot in place. Fill the jar with water, stopping when the water level is about ¼ inch above the bottom of the net pot. Filtered or reverse osmosis water is best. Be sure to add hydroponic nutrients at this time. Place a thin layer of hydroton pellets in the bottom of the net pot. Next, put the rockwool growing cube containing the sprouted seedling onto the hydroton pellets. Continue carefully placing hydroton pellets around and on top of the rockwool cube. Place your hydroponic mason jar garden in a sunny location or provide adequate artificial light.It is also possible to simply root and grow various plants in a jar of water, changing it out as needed. Maintaining your hydroponic plants in a jar is as simple as giving them plenty of light and adding water as needed!
