Grow your own microgreens
Looking at the above advantages, who wouldn’t like to have microgreens grown hydroponically. So, let’s have a look at the steps required to grow your own young microgreens.
STEP-1: Gather all the supplies
By growing microgreens hydroponically means growing them in an aquatic-based environment. Therefore, in this case, microgreens would be receiving the required nutrients and oxygen from water instead of soil. To be ready, let’s gather all the supplies needed to grow microgreens hydroponically.
The first and foremost thing is to buy good microgreen seeds. Since microgreens are not regular plants, they cannot grow from regular vegetable seeds, so make sure to buy microgreen-specific seeds.
Since we are not using soil to grow microgreens, we need another way to keep the seed in its right place all the time while sprouting. Mediums provide support to the roots to grow microgreens. Some of the mediums are:
- Coconut coir
Using coconut coir is one of the cheapest mediums. Put coconut coir in a jug or bucket and add some water. Then stir and mix it well till the mixture converts into a soil-like consistency. Leave the mixture for 30-45 minutes. After that, remove the excess water, and the medium is now ready to grow microgreen.
Vermiculite is made up of natural minerals and is light in weight. It has a good water retention capacity. Vermiculite prevents the medium from turning in waterlogged. It is an approved growing medium for many plants.
- Clay stones
Clay stones can also be used to grow microgreens. It become porous when mixed with water and thus hold the water and air to provide it to the microgreen.
- Hemp growing mats
Hemp growing mat is the best option available to grow microgreen. It provides nutrition to the seed. Using hemp-growing mats is the easiest way. You just have to moist the mat with a sprayer, and it is good to be used. However, Hemp growing mats are the most expensive way to grow microgreens out of all.
To grow microgreens without soil, a big tray is a must. The growing tray is used to place the growing medium properly to grow the microgreen. Various varieties of the tray are available in the market. For growing microgreens, a tray with a depth of around 1.5-2.0 inches is preferred.
The first stage of growing microgreens hydroponically is to germinate the seeds, to help the germination process, you need to provide growing lights to the microgreens for the photosynthesis process after 4-5 days.
For growing light, you can use direct sunlight, or any LED grow light can be used to serve the purpose.
pH testing kit
To grow the microgreens hydroponically, a regular check of the pH of water from time to time is necessary for the better health of the plant as it affects the growth of microgreens.
The recommended water pH for growing microgreens is six. To check the pH of water regularly, a pH testing kit is required.
Nutrients and fertilizers
As we all know, nutrients are a must for the growth of any living organism; we need to use good nutrients or fertilizers for the better growth of your microgreens.
The spray bottle is the best way to provide water to the microgreens. After using the bottle, make sure to clean it because bottles might contain some dangerous chemicals that can harm the microgreens.
After getting all the supplies, let’s move towards the steps to grow microgreens without soil:
The quality of water matters a lot in the hydroponic method. Rain and distilled water are best to grow microgreens without soil, but if distilled or rainwater isn’t available, then tap water can be used after boiling it.
Use the Ph kit to identify the pH of the water and adjust it. To raise the pH of water, ash, lemon drops, or phosphoric acid can be used to maintain the pH to be around six.
Along with this, make sure to use a spray bottle to give water to the microgreens.
Fill the trays with medium.
First, prepare the medium across the trays. Spread the coconut coir or any of your preferred mediums in the tray properly so that the surface becomes plain.
If you are using a mat, then use only one mat; it does not require more than one mat.
Plant the seed
Take two or three spoons of seeds and spread the seeds across the tray with a growing medium. Keep notice of the fact that there shouldn’t be any spots and large lumps of seeds in a single place.
Microgreens do not require large space to grow, so they can be kept anywhere in the house or gardens.
After spreading the seeds across the tray, keep the seed and the medium moist.
As previously mentioned, using a spray bottle is the most preferred way to maintain moisture.
Germinate the seeds
Microgreens take around 4-5 days to germinate. At the time of summer, keep the microgreens in the dark area.
After five days, the process of germinating begins, and the seed starts sprouting, so use the LED light or put the microgreen in the direct sunlight to help the germination process.
Keep under grow lights
After sprouting, microgreen requires a dry and soak method.
The dry and soak method includes putting the sprout in water for 10-15 minutes and then removing it, and letting the microgreen dry. This should be done on a daily basis for the better growth of microgreens.
Wait for harvest
It requires around two weeks after the sprouting of microgreens. Till that time, only use the dry and soak method.
In the 3rd week, small leaves will start appearing on the top of the microgreens. At this point, it is important to harvest the microgreens. For harvesting, you need a pair of scissors to cut the microgreen but keep in mind to cut the stems only, not the roots. It provides nutrition and freshness to microgreens.
