Types of Seed Starters

There are many types of seed starters. We have listed three main types of seed starters which you can use and experiment with which one is the best option for you.

1. Conventional Trays and Cell Flats

Molded plastic seedling trays are famous for 1020 deep trays because their sizes are around 10 inches by 20 inches. They are easy to fill, carry, and recycle. Cell flats, also well-known as plug flats, fit in 1020 seedling trays and are accessible in many sizes. The most popular choices for vegetable transplants are 50’s, 72’s, 128’s, and 200’s cell propagation trays. For larger crops they offer Cell flats with 38 or 24 cells per flat, resulting in large root balls and canopy development.

A new method is to spread seeds in channels for germination; when the seeds begin to show true leaves, they are “bumped up” or “potted up” into cell flats. This marks a 20-row seed flat. Seed flats save area in the germination space or on the seedling heat mat.

Advantages:

Trays and cell flats are usual seed-starting methods for big vegetable farms because they are quick to fill, easy to transport, and recyclable.

Disadvantages:

They can root-bound seedlings, you must prepare and store them because you cannot recycle them. Bleach alternatives with a peroxide basis, such as OxiDate, are advised to avoid illness. You can determine recyclability by the plastic’s makeup and the guidelines of the local recycling skills.

2. Biodegradable Pots

Fertil wood fiber pots serve as separate planting new pots that are used with seedlings. Later, the pot decomposes in the soil, leaving water, soil nutrients, and roots to flow.

Advantages:

Home gardeners and business transplant gardeners use biodegradable pots because they cut the shock of transplants and are easy to plant and non-recyclable.

Disadvantages:

Biodegradable planters take up more room in greenhouses and need to be refilled based on the season. They also need a transport tray. If they remain exposed for a long time, they can cause the root-bound seedlings.

3. Soil Block

Soil blocks are potting media cubes made by Soil-Block Manufacturers that help seedlings reproduce in an independent block. They are available in many sizes, such as tiny ¾” mini-blocks that may be customized with different-sized dibbles to accommodate various seed types.

Advantages:

Soil blocks nurture good plants through the use of air pruning technology in which seedling roots dehydrate and form secondary roots, resulting in a strong root system and rapid seed establishment after transplantation.

Disadvantages:

Soil blocks are a steadfast and effective method for rapid growth, but their labor-intensive nature may make them less profitable for improved producers or those with limited time.

4. DIY Seed Starter Kits:

You can make your own seed starters from things available at your home. These include egg cartons, yogurt containers, newspaper pots and other recycled materials. These are very cheap as well as environment friendly.

Where to find seed starters?

You can find seed starters in any garden center, local nurseries, and online retailers like Etsy, Amazon. You may focus on where you can get cheap seed starters without breaking the bank, because if you plant many it can get very expensive. Dollar stores, nearby nurseries and even DIY kits work best. You can also find seed starter materials like air prune trays, peat pallets, soil mix, peat pots and heat mats.

Cell Seed Starter Trays

These cell seed starter trays are crucial for indoor plant seedlings because they offer enough sunlight, and drainage. Cell seed starter also promote healthy growth, assist in managing and growing the prospect of accomplishment and come in various sizes and materials. There are trays with 12 to 128 cells; for small-seeded crops like lettuces and tomatoes, 24 to 48 cells work well. 6-cell trays are also available in the market. These trays get the air-pruning benefits of soil blocking without creating any untidiness and come with plastic lid as well.

How to use seed starter trays and kits?

Growing plants from seeds is a wonderful method to start gardening early in the season. You can grow your plants from seeds with the help of accurate light and simple equipment.

1. Gather all the materials:

Gather all the materials which include Seeds, pots or required size cell trays, Plant markers, Seed starting mix, seed tray with humidity dome and Spray bottle filled with water.

2. Fill your pots or trays with seed starting mix:

Take a large tub or bucket and add your seed starting mix in it then, add the plentiful amount of water and mix it with a trowel or your hand. Add more water as necessary when the seed starting mix begins to absorb the moisture. (This will take a few minutes because the mixtures including peat soak). Damp the mixture like wet sand.

3. Sow your seeds:

Push the seeds into the seed-starting mix. You do not need to cover the larger seeds because they need space for ventilation, whereas smaller seeds can be left open. Larger seeds should be covered with vermiculite or a seed-starting mixture the same height as the seed.

4. Label your planted seeds:

Use inexpensive plastic markers for early seedlings, and save large metal markers for the garden.

5. Keep your seeds moist and warm:

After misting the seeds with water, place pots together on a tray, cover them with a humidity dome and add heat. For ideal humidity levels, place in a warm area. Seeds start germinating after three weeks, but some may take a couple of days to several weeks to do so. Consider self watering planters to ease off your busy schedule.

6. Provide light to seedlings:

Remove the humidity dome and place the seedlings in a sunny light; ensure the mixture is moist but not soggy. Water them every day or every other day because they flourish in little media and do not soak them completely like loftier plants.

7. Transplant seedlings indoors:

When the first set of leaves appears, move the seedlings. Pick a strong seed and transfer it to a DIY larger pot. Add water to the potting mixture and place it in sunlight every day.

8. Harden off those seedlings:

Your seedling will become resistant to the outdoors if it is allowed to spend extended periods in full daylight after being moved from indirect light at night.

9. Transplant your seedlings outdoors:

After the seasoning period, move your seedling to its ultimate location, either into your garden, a pot or even raised garden bed, and enjoy the fruits and vegetables in a few months.

How to control and avoid fungus growth in seed starter kits?

  1. Some experts suggest sterilizing potting mix. Put it in a deep baking tray, wet it until damp cover with foil tightly and bake at 72°C (160 F) for 15 mins. Generally, this applies to 330 grams of soil and kills germs and bugs.
  2. If you save your own seeds, it is more likely to develop fungus than commercial seeds.
  3. You can sterilize your garden tools. However, washing all containers and garden tools in a one part bleach to ten parts water mixture works well too.
  4. Try Planting your seeds in warm (to resemble tropical environment) potting mix.
  5. If you are a seed saver, keep in mind that saved seeds are more likely to develop fungus than commercial seeds.
  6. When growing seedlings take precaution not to over-water them. Consider bottom watering your seedlings to avoid mold and root rot.
  7. crowd one another once they grow. Crowding reduces adequate airflow and can lead to fungus. Therefore, thin out your plants by removing some seedlings once they start to take roots and repot your seedlings without waiting too long.

Are seed starter kits worth it?

Seed starter kits allow you to get a head start on the growing season ensuring that your plants are healthy and strong when ready to transplant. You can save money by using a seed starter kit. But it also depends upon the gardener’s choice or requirements.
