How to Grow Wheat Grass Hydroponically

Overview

Wheat grass contains many important vitamins, enzymes and amino acids, as well as chlorophyll, and it is a popular addition to healthy juices, smoothies and other beverages. Many people use wheat grass as a detoxifier, for a natural energy boost or for bolstering their immune system. Cats also appreciate having a tray of fresh wheat grass to nibble on. Wheat grass is most commonly grown in soil, but you can grow wheat grass at home hydroponically, too.

Step 1

Purchase whole wheat berries, also called wheat seeds or wheatgrass seeds. Wheat berries may be found in sprouting or juicing supply catalogs, or in the bulk section of natural food stores. Both white and red wheat berries can be sprouted into wheat grass.

Step 2

Rinse the wheat berries in a sieve with cool running water. Soak them in fresh water in a jar or bowl for eight to 12 hours. You may also soak them in kelp fertilizer mixed according to the directions on the package.

Step 3

Wet down several sheets of paper towel and lay them inside of the greenhouse tray. The paper towel should be very wet but without any standing water.

Step 4

Drain the wheat berries and spread them over the paper towel. Cover the tray loosely with plastic wrap.

Step 5

Spray the seeds with water two or three times a day until they germinate and put out roots. This should occur in two to three days. Keep the wheat berries evenly moist but not waterlogged. Wheat grass should be grown under indirect sunlight with temperatures between 60 and 75 degrees Fahrenheit.

Step 6

Add about 1/2 cup of water to the tray when the seeds have put out leaves and are starting to push up against the plastic wrap. If your house is very dry, keep the plastic wrap on to hold in moisture, otherwise remove the plastic wrap to prevent mold growth.

Step 7

Add 1/2 cup of water or kelp fertilizer every day until the wheat grass is four to eight inches tall.

Step 8

Harvest the wheat grass by cutting it with scissors just above the roots. Juice or blend as desired. If you are growing wheat grass for your cats, you may allow them to eat directly from the tray, although you should limit their access at first to see how they react. Some cats may vomit if they eat too much wheat grass; it's best to ask your vet before letting your cats eat it.
