Since you only eat the sprouts, you want to buy a large number of seeds.  The more seeds you have, the more you can produce.  Remember, it is eaten as very small grass. 

So if you want to make a juice you need to blend a decent amount to even have one shot.   This is why it is best for you to buy seeds in bulk.

Once you have located the seeds, you can start.  The first thing you should do is soak your seeds for at least 8 hours.  To increase success, you can use water from your aquaponics tank to soak the seeds. 

Make sure that the seeds are fully submerged in the water.  During this time, it is best to keep the seeds in a dark and cool place.  

The process of soaking the seeds softens the hard seed coat, making it easier for the sprouts to come out.  In fact, you can use this method with almost all seeds.  

After the seeds have soaked for 8 hours, drain all the water out.  At this point, keep the seeds covered with a towel to keep the moisture in.  Keep it out of the sun and heat.  

The seeds will continue to germinate over the course of the next hours.  Keep them there for at least another 8 hours.  

After 8 more hours, you can rinse the seeds with water again then let them sit.  You can continue this rinsing and sitting process until you see a sprout forming.

Wheatgrass and Sprouts

The sprout will look like a small white string coming out of the seed.  At this point, you are ready to transplant them into your aquaponics system.  

Be sure to not soak your seeds for too long and observe them carefully.  If you see mold growing, the health of your seeds can be compromised.  Make sure to not soak too many seeds in one container.  

Before you transplant, let the seeds dry out a bit.  One of the best growing mediums for wheatgrass is hemp or coconut fiber sheet.  This is because it wicks water but doesn’t get too moist.  

If you can find it, prepare your growing beds by laying the sheet at the bottom of your growing container.  At this point, you can simply place the seeds on top of this sheet and cover it with a cloth.  

This cloth helps keep the moisture in and helps speed up the germination process.  As you flood your grow beds with water from your fish tank, the wheatgrass will continue to grow. 

Once you see some green emerging, you can remove the linen cloth.  At this point, your sprouts will need sun.  Make sure you have a good location for them to grow.  

Typically, one grows bed that is 10 inches by 20 inches can take about 6-8 cups of wheatgrass seed.  Using this rule, you can maximize your wheatgrass growth. 

Continue to water the plants and give them sun until they reach a good size for consumption.  So when to harvest wheatgrass?  The optimum time to harvest is when they reach between 5 to 6 inches in height.  

Once your seeds germinate, they can grow to this size within 1-2 weeks!  As you can see it’s super fast!
