How to Grow Wheat Grass in Greenhouse: A Step-By-Step Guide for Seed to Harvest

As a dietary supplement or in juice form, Wheatgrass is commonly consumed for its health benefits. Wheatgrass can also make smoothies, salads, and other dishes. A great source of vitamins, minerals, and antioxidants, Wheatgrass boosts your immune system and overall health. It is more cost-effective to grow Wheatgrass at home than to buy it at a store. Conditions can be controlled completely by you.

To ensure that your Wheatgrass is organic and pesticide-free, you can invest in non-treated Wheatgrass seeds. Growing Wheatgrass in a greenhouse requires daily attention and care, including watering and monitoring for mold and pests. It takes up to two weeks for Wheatgrass to grow to a sufficient height, so patience is required.

How to Grow Wheat Grass in Greenhouse

Germinating and Planting Wheat Grass

Crops that grow quickly, such as Wheatgrass, are not difficult to grow once you have learned the basics. There is no season for growing Wheatgrass, so you can start growing it anytime.
Before soaking the seeds, measure them and rinse them well. A 16 x 16-inch tray needs two cups of Wheatgrass seeds. Seeds should be rinsed under cool water and drained thoroughly.
Cover the seeds in a bowl with cool, preferably filtered water.
Ensure the seeds are completely covered with water, and cover the bowl with plastic wrap. Sprouting is best at 15-21°C.
Let soak overnight at room temperature or for about 10 hours on the counter.
Once the seeds have been soaked, drain their water and replace it with cold water. Again, let it sit for 10 hours.
Repeat the process one more time for a total of three soaks. The seeds should have sprouted by the end of the last soak.
Set them aside until you are ready to plant them after draining them.
As the Wheatgrass growing medium, use a tray with holes at the bottom. Paper towels should cover the tray’s bottom so the seeds do not slip.
Spread an even layer of organic compost or potting soil in the tray. It is best to use an organic potting mix.
A thin layer of seeds should be spread over the compost or potting soil in an even layer.
Don’t bury them; just lightly press them into the soil. Simply cover the soil with the seeds to plant them.
Make sure each seed gets a little water by watering lightly.
For protection, place a few damp sheets of newspaper over the tray.
Keep the seeds damp by spraying them with water while they grow.
You can remove the newspaper cover after about four days. The Wheatgrass should be watered once a day with a spray bottle.
Cover your tray with another tray that has been flipped upside down. Keeping the growing area dark and moist is crucial during the early stages of growth.
Wheatgrass should be kept in partial sunlight and have good air circulation. Within 9-10 days, your Wheatgrass should be ready for harvesting.

Light Requirements for Wheatgrass Growing in Greenhouse

Wheatgrass should be kept in the dark for at least a few days after sprouting. As a result, the soil appears dark beneath the surface. You can remove the cover after 3-5 days. By that time, your grass should be about an inch tall. Despite looking pale, it hasn’t had regular access to sunlight.

Your uncovered tray should be placed near an indirect light source. The plant will begin to green up. It’s fine if it gets direct sun for short periods. Creating that brilliant green hue is the goal. If your tray doesn’t get direct sun for most of the day, move it after a couple more days. If it needs more water, check that your growing medium regularly has what it needs.

Temperature Requirements for Wheatgrass Growing in Greenhouse

Temperatures between 15-21°C are ideal for starting your crop. The best way to maintain the optimal range is to grow it indoors. Your young grass can tolerate lower or hotter temperatures once it reaches 1/4 to 11.2 inches in height, provided its roots stay comfortable. Ensure any covered Wheatgrass trays have adequate ventilation if the temperature exceeds 27°C.

Watering Requirements for Wheatgrass Growing in Greenhouse

A misting bottle should be used twice a day to water it lightly. At first, you just want to keep the sprouts moist enough so they can get their roots into the soil. You should keep the potting medium or growing medium moist but not wet once the roots have set down. You will see vibrant, green growth as a result of keeping your sprouts moist.

You should check your growing medium regularly if your tray is exposed to the full sun regularly. The plant may need more water than twice a day at that point. If the soil or medium isn’t very moist, spritz it more frequently. Letting water pool on top of coir, grow mats, or potting mix is never a good idea. Wheatgrass can drown if it is given too much water.

Fertilizing Requirements for Wheatgrass Growing in Greenhouse

You can dilute some liquid kelp in the spray bottle you are using to water your Wheatgrass to boost its growth. Watering with this shouldn’t be necessary every time, but it can definitely speed up the growth.

Harvesting Wheatgrass Grown Greenhouse

Wheatgrass should be harvested when it has reached the jointing stage. In this stage, the leaf begins to split or form a secondary leaf. Generally, this occurs when the plant reaches a height of 7-8 inches. However, the plant can be harvested as young as 6 inches in height. To harvest, cut the grass just above the root joint or any seed remnants with a sharp pair of scissors. It is also possible to use a super-sharp knife if it slices cleanly through the grass without ripping it out.

Multiple crops can be grown from a particular batch of seeds without noticeable flavor changes. Add liquid kelp fertilizer if you want to promote fresh growth after harvesting. Before replanting a tray, people usually get two to three crops. The best way to get freshness is to harvest right before use.

Conclusion

It is easy to grow Wheatgrass greenhouses in small trays for use in healthy recipes. Seeds of Wheat are soaked in clean water for several hours, then placed on moist potting soil and kept moist until they germinate. After planting the seeds, they grow thin white roots and nutrient-rich edible green shoots. When harvested from Wheatgrass, its healthy green blades can be used immediately for juicing and smoothies.
