Wheatgrass can be grown hydroponically or with soil. The hydroponic method means that you grow using water and a growing mat instead of soil.
What are the benefits of the hydroponic method?
The benefits of the hydroponic method is that there is less mess (you'll have no messy soil to deal with) and it's quicker to set up your growing trays.
The Sure to Grow mat is a pH balanced, hydroponic growing media which is made of recycled PET bottles. It's a no-mess system that makes growing wheatgrass easy.
Soak 300g of wheatgrass seeds in water for 6 hours (summer) or 12 hours (winter). 300g is suitable for a large growing tray that is approximately 55cm x 35cm. For smaller trays, reduce the quantity of seeds.
Rinse and drain your seeds using a sprouting bag or a sprouting jar. If you are using a sprouting jar, leave your jar upside down (with the straining mesh lid) for approximately 12 hours. You can leave it upside down in a large bowl or on a dish drainer. If you are using a sprouting bag, hang it up for 12 hours and leave it to drain.
Rinse your seeds with water. Repeat step 2 until your seeds sprout (this usually takes 24 hours depending on the climate). Your seeds are ready to plant when they have a small tail of approx 2mm. Please note: A key to minimising mould is to not let your seeds sprout too long. Once the seed tail is longer than 2mm, you may have problems with clumping and mould.
Completely saturate your growing mat with water. Place the mat inside a growing tray which has drainage holes. Put a drip tray underneath.
Spray a small quantity of diluted liquid seaweed fertiliser (follow instructions on bottle and reduce quantity to suit your tray size) over your growing mat.
Sprinkle seeds evenly over your growing mat and ensure that there are no gaps. Don't overcrowd your seeds as it will cause mould problems.
Cover seeds with wet paper towels or a hessian bag. Water your seeds and place your tray in a dark spot. Water 1-2 times a day using a spray mist bottle until your plant grows 1-2 inches. Please note:Don't overwater. Your growing mat will need to stay slightly damp without being saturated or having 'pools of water'.
Uncover your wheatgrass and place your tray in the light. You can grow your wheatgrass near a sunny window or outside in a shady spot. Please note: Avoid extreme heat and cold. Keep well ventilated.
Water 1-2 times daily with a spray mist bottle. Once they are 3-4 inches tall they are ready to harvest.
To harvest, cut the wheatgrass approximately 1 inch above the soil. Don't worry about mould as it is perfectly normal in Australia's humid weather. Harvest your wheat grass above the mould.
