Best Fertilizer For Microgreens

Microgreens are fast-growing plants that are just beginning to sprout from seeds, and they can be grown indoors or outdoors. If you’re interested in growing microgreens, you’ll want to make sure you have the best fertilizer for microgreens so that your plants grow quickly and healthy.

The best fertilizer for microgreens is Grow Big All-Purpose Fertilizer, which can be used on any type of plant. It contains nutrients that will help microgreens grow quickly and produce a high yield. You can use Grow Big All-Purpose Fertilizer on soil or hydroponically.

Best Fertilizer For Microgreens

There are many different kinds of microgreens fertilizers available on the market. If you’re not sure which one to use, read on to learn more. You can use cottonseed meal, Rockwool, Hemp mats, or liquid kelp. Some are better than others. Read the labels carefully and use them according to the instructions. Organic fertilizers are safer and more effective at providing your plants with nutrients.

Liquid kelp

While most gardeners do not think about liquid kelp as a fertilizer for their microgreens, it can help the plants grow. Kelp is an excellent source of many nutrients, including choline and vitamin B. Niacin is a vital nutrient that aids in proper cell division. It is also rich in trace minerals and other nutrients that are essential for the growth of any plant.

As a liquid kelp fertilizer, this product contains more than 70 types of minerals and plant growth hormones. It is especially beneficial for microgreens grown in soilless, hydroponic media. As a natural fertilizer, it encourages plants to draw nutrients from the soil, making them more efficient growing machines. You will need to mix the liquid kelp with water and spray it directly on the microgreens.

In addition to using liquid kelp as a fertilizer, you can also use fish emulsion. However, this option is not advisable for microgreens because it is not suitable for indoor use due to their foul smell. A more effective option is to use a blood meal, which is a completely organic fertilizer made from the dried blood of animals. However, be careful when choosing a liquid kelp fertilizer for microgreens, as it contains traces of animal products.

Aside from being effective for microgreens, using an organic fertilizer can have health benefits for your microgreens. It also increases the perceived value of your microgreens. You may even be able to sell your microgreens for more profit by using organic fertilizers. A few examples of organic fertilizers include Liquid Kelp, Rock Phosphate, Bat guano, Cottonseed meal, and Bone Meal.

Cottonseed meal

One of the most common ingredients in microgreens is cottonseed meal. It is an organic fertilizer, but if you’re growing them as a container crop, you may want to consider something a bit more natural. Other options include Azomite or FloraGro, which are both derived from volcanic ash. Despite their name, both products contain nutrients essential to plant growth. Azomite is generally best applied before planting to maximize its effect.

Compost, also known as black gold, is a mixture of decomposing organic materials. When applied to microgreen soil, this organic material enhances the quality of the soil and allows roots to absorb nutrients directly from the source. Compost continues to decompose while microgreens grow, providing nutrients even more efficiently than fertilizers. And compost is cheaper than fertilizer, especially if you do it yourself.

Coconut coir is a natural material that is great for retaining moisture. It’s similar to burlap or vermiculite, but it’s less flexible. Coconut coir is great for preventing mold from developing on microgreens, but it’s also messy and does not contain nearly as much nutrition as the soil does. You can buy dehydrated coconut coir in dehydrated blocks or sheets.

Commercially available fertilizers can be harmful to microgreens, and many have synthetic ingredients. If you’re using soilless mediums, consider using liquid kelp instead. This organic substance contains seventy different minerals and plant growth hormones. Liquid kelp works well with soilless media and prevents microgreens from overfeeding. If you’re not sure whether liquid kelp is right for your microgreens, try mixing two or three tablespoons of it with your soilless medium.

Hemp mats

Hemp mats are a great way to grow your microgreens at home and are an excellent choice for a soilless growing medium. Although hemp mats don’t require any fertilizer, they will force your plants to grow upright, so they might have smaller leaves. The other benefit of using hemp mats is that they cost less than soil. They are also a great option for those who want to grow their own food but don’t want to spend the money on buying fertilizer.

Hemp mats can be used for growing a variety of plants, from salad greens to microgreens. The best way to use hemp mats is to soak your seeds in them for a day or two. Coconut coir or hemp mats are a great choice, but hemp mats will retain more humidity and are more economical than cocopeat. These mats are biodegradable, compostable, and reusable.

Another advantage of hemp mats is that they are naturally pest-free and will break down in about two weeks. Hemp fibers help regulate moisture levels near the roots of the plants, so they’re great for microgreens. Another benefit of hemp mats is that they’re easy to use. The hemp mats are made from hemp fiber, and they’re compostable after use.


Growing your own microgreens requires a special culture medium. Rockwool is the best choice for this purpose. The clones can survive in it for months if you properly care for them. Rockwool cubes should have roots growing through them from all sides. Rockwool cubes can be easily transported. The clones should be transplanted into a tray or pot at least three weeks before they begin to wither.

The main disadvantage of Rockwool is that it is difficult to dispose of. It is a product of melted rock and usually comes with a high pH. Additionally, it can be harmful to the eyes, nose, and lungs if you breathe in the dust. That’s why many microgreen enthusiasts choose starter plugs to sprout seeds. It is important to know what Rockwool is and how to use it properly.

When using rock wool as fertilizer, you should be very careful not to soak it completely. When you place the cubes in the soil, they absorb water more than nutrients. Besides, too much moisture can make the soil anaerobic and the seeds will not be able to germinate. As rock wool retains more water than the soil, it is important to avoid fully submerging them in water.

Fish emulsion

If you are growing your microgreens indoors, fish emulsion is an excellent choice. It contains calcium and phosphorus and can help balance the pH level in your media. Because peat moss and coconut coir are acidic, adding a supplement like fish emulsion is helpful. Adding limestone to your soilless medium can also help balance the pH. Plants grown in these soilless mediums have a high success rate.

One disadvantage of fish emulsion fertilizer is its odor. It can be quite overwhelming indoors, but the smell will dissipate within a day or two. However, it is an effective fertilizer for microgreens and can be applied as a foliar spray or soil drench. Moreover, you can add a few tablespoons of the diluted fish emulsion to your compost pile once you are done with the growing season.

In addition to the fish emulsion, the fish meal can also be used as a fertilizer. It is a byproduct of fish oil extraction. It is made of leftover fish material and then processed through a steam bath. This process allows the emulsion to remain in liquid form, thus preserving its essential amino acids. Compared to chemical fertilizers, fish and seaweed emulsions are easily workable through the soil.

Blood meal

While the best soil for your outdoor garden contains peat, there are several other nutrients you can use as a fertilizer. You can use kitchen scrap compost or rock dust, but you may want to try blood meal, as it is organic and contains no harmful pesticides or chemicals. If you choose to use soil, be sure to sterilize it first, by placing it in the oven or spreading it on a plastic sheet in the sun.

Compost, also known as black gold, is a natural way to fertilize your soil. By mixing it with soil and other ingredients, compost enriches the soil and allows microgreen roots to absorb nutrients directly from the source. Better yet, compost is also cheaper than fertilizer, especially if you decide to make it yourself. Besides, you can also make compost yourself by using eggshells and coffee grounds.

Peat moss is an excellent source of plant nutrients. It contains zinc, iron, calcium, and micronutrients, and is generally 6-2-1 in NPK. Peat moss is also great for keeping seeds moist and strong as they germinate. However, you shouldn’t use it for hydroponic microgreens because the peat moss is not pH-neutral.
