What is a Seed Starter Kit?

A seed starter kit is a tool designed for sowing seeds to facilitate germination and seedling growth before transplanting into a larger growing media, like a garden bed or pot. However, you can also use starter kits for planting seedlings. Typically, a seed starter kit comes in handy during the winter season when the outdoors is too cold to plant anything in planters or straight into the ground.

Nonetheless, you can use a seed starter kit even in warmer seasons. Since these kits are designed for indoor use, they offer the right conditions (including high temperature and humidity) for faster and more successful seed germination. Ultimately, using a seed starter kit increases the seed and seedling survivability rate.

Different kits offer varying tools, but, in general, a seed starter kit comprises a cell tray insert, a base tray, a humidity dome/lid, grow light, and a heat mat/pad. Some kits may also feature growing media, such as seed starting mixes, peat pellets, or coconut coir, to mention a few.

Cell tray inserts: Also known as the seed tray or seed starting tray, the cell tray insert features individual cells where you can plant the seeds. The smaller cells make it easier to sow a seed and manage it through watering. A single-cell tray insert can accommodate between 6 and 128 seeds.

Base tray: The base tray holds the cell tray insert. Seed trays are usually molded with drain holes at the bottom of each cell to prevent overwatering. The water that drains from the cell tray drains into the base tray. In other kit designs, a base tray can also be used for other styles of planting, such as hydroponics or peat pellet growing media where the cells are unnecessary. Self-watering kits also use the base tray to support the hydration sponge that absorbs the water to supply the roots.

Humidity dome: The humidity dome acts as a lid, covering the cell tray and base tray. This tool is usually clear to allow for natural lighting control. It also comes with adjustable vents where you can control the humidity and temperature to mimic greenhouse conditions. Some dome lids are usually built with grow lights for even better light control.

Grow light: A grow light is usually fitted into the dome or comes separately, allowing you to clip them where you will place the kits. Grow lights provide the full spectrum of light needed to facilitate plant growth and photosynthesis.

Heat mat/pad: A heat mat or pad is usually placed underneath the trays and helps to increase the soil or growing media temperature to speed up seed germination.

Growing media: This is where you sow the actual seeds. You can either use seed starting mixes or organic materials, such as peat or coco coir, to name a few.

Why Use a Seed Starter Kit?

A seed starter kit comes in handy for gardeners and plant growers of all levels. Using a seed starter kit guarantees better results for your seed starting process, enhancing the seedlings’ survivability rate. Moreover, seed starters make the seed-starting process easier and more convenient.

Here are the common benefits of using a seed starter kit;

Seed Starter Kits Provide the Perfect Conditions

 Unlike other tools, seed starter kits are specially designed for seed starting. Therefore, they offer the perfect conditions to promote faster seed germination and seedling growth. The best seed starter kits offer the perfect balance of temperature, humidity, lighting, drainage, and the growing media setup. For instance, sowing a seed into a large pot increases the possibility of the soil pushing down on the seed, damaging it and preventing germination.

Similarly, the pot may not provide the right amount of moisture, drainage, or humidity for seed germination. On the other hand, a seed starting tray, whether it’s cell or organic growing media, offers just the perfect small space for sowing seeds to guarantee germination.

Variety of Designs to Choose From

 Seed starting kits come in a variety of designs and styles based on your needs. For instance, if you are a beginner or want to enjoy more convenience, a self-watering kit is a great option. Your seeds are guaranteed to germinate and grow without the hassle of worrying about watering them daily.

Another great example is seed starters that involve organic biodegradable growing media. For example, you can use seed trays made from peat to sow your seeds. This means that when the seeds grow into seedlings and are ready for transplanting, you don’t have to remove them from the cells.

Instead, you simply plant them into the garden bed or pot while still inside the cells. The biodegradable cells will eventually break down entirely in the soil without affecting the plant or the environment. This style of seed starter comes with the advantage of preventing root shock or damage while making transplanting easier and mess-free.

Come with Tools to Fine Tune the Environment

Unlike other tools, seed starter kits allow you to fine-tune the environment. You get accessories, such as a humidity dome, grow light, and heat mat, among others to accurately control the humidity, lighting, and temperature, to mention a few. Adjusting these parameters helps to speed up germination and growth of seedlings.

Watering is Easier

Seed starting kits are easier to water due to the uniform-sized cell. Moreover, they are designed to facilitate drainage which ensures you never deal with overwatering.

They Help You Get Organized

In general, a single seed tray can have anywhere from 6 to 128 cells – that is 6 to 128 seeds per tray. This design helps you better organize your seedlings and plant more seeds without taking up a lot of space. You can even group your plants if you have different ones.

For instance, one tray can be for herbs, the other for vegetables, and so on. This even makes it easier to handle them. This is because different plants will require transplanting at different periods and intervals.

How To Use A Seed Starter Kit

Different seed starter kits will come with their own operating instructions based on the brand and design. However, they also follow a standard working design, as long as they have the standard parts. These include seed trays, base trays, and humidity domes. Here’s a standard guideline on how to use a seed starter kit;

Prepare the Growing Media

On each cell on the tray, you intend to sow a seed and add the growing media. This can be the seed starting mix, dried peat pellets, or dried coconut coir. If you are using dried peat pellets or coconut coir, you want to activate them so they can expand in size by adding hot water. If you’ve used seed starting mix, moisten it using room temperature water. Tamp down the mix and add more until it covers the entire cells, ensuring the entire mix is moist and damp.

Sow the Seeds

In each cell, create a shallow hole in the dirt, put a single seed, and lightly cover it with the dirt. Spray the cells with some water.

Increase the temperature

If your kit has a dome, cover the ray to keep the interior humid and warm. You can also transfer the entire kit onto a mat to help raise the temperature of the growing media. The ideal temperature for seed germination is typically between 75 and 90 degrees Fahrenheit.

If you use a heat mat, always be vigilant with the plant. You have to remove the heat mat immediately and start to adjust the dome vents to lower the temperature and reduce humidity. This is because higher temperatures and humidity can easily overheat the newly sprouted seedlings.

Add Lighting

Place your kit where there’s access to natural lighting, like a windowsill. You will notice that seed starter kit humidity domes are clear, to allow for the light to penetrate. If you don’t have access to enough natural lighting, you can invest in growing lights. Grow lights allow you to adjust the dim levels and even the timing. Seed germination and seedling growth require lighting at different levels, for at least 6 to 12 hours daily.

Don’t Forget Watering

Watering is another important part of seed starting. Your seeds will not germinate if they don’t get enough water and dry out! You can ensure adequate hydration by spraying the top and hydrating from the bottom.

Simply fill water on the base tray and the seedling will absorb the water through the drain holes and into the roots. Don’t worry, this type of watering allows for gradual water uptake so your plants never suffer from overwatering.

Transplant

After seeds have germinated and seedlings are about to overgrow the cells, it’s time to transplant. Use a widger and dibber to remove the seedlings with their growing media from the cells into the ground or pot. If you use biodegradable cells – even better- simply transfer the cells with the seedlings into the garden bed or pot.

Buying Guide: How to Choose the Best Seed Starter Kit

Ready to order your seed starting kit but don’t know which one to get? Here’s a detailed buyer’s guide to help you choose the best seed starting kit for your needs.

Growing Materials and Media

While some do, most seed starter kits don’t come with the growing media. The growing media is where you sow the seeds. These include seed starting mixes or organic material, such as peat moss or coconut coir, or husks. You want to observe the design of your kit to determine which medium to get. But, other kits may accommodate different media, depending on your needs.

Kit Materials

The material used for the starter kit determines many of its features, including durability and reusability.

Plastic

Most plastic kits are reusable – all you need to do is wash and reuse. In fact, you can even find good quality food-grade options, such as PET, ABS, rubber, and silicone that allow you to use the dishwasher. But, if you want a more durable option you can use more than once or twice, go for thicker plastic that won’t crack or snap under pressure or in extreme weather conditions. Different types of plastic material also come with additional perks. For example, silicone and rubber are pliable and flexible so you will notice that many of its kits offer pop-out cells that make it easier to remove the seedlings for transplanting. Silicone also has a smoother surface which makes cleaning easier.

Biodegradable

Material, such as peat, paper, or coconut coir can also be used as the kit material, particularly the seed trays.  Seed starter kits, such as Growner Peat Pots Seed Starter Trays are made from peat cell trays. You can cut each cell on the tray using scissors once you have the seedling for easy transplanting. You plant the cell along with the plant and allow the cell to decompose in the ground without affecting the environment. This is an excellent solution for curbing the risk of root damage or shock. As these biodegradable trays break down, they can even fix the soil and act as fertilizer. Unfortunately, biodegradable options are not reusable.

Bamboo and wood

Bamboo is another durable and reusable option. It is naturally rugged and can last you for as long as 5 years when used right. On the other hand, wood isn’t as durable as bamboo. This is because it is susceptible to rot caused by microbial, oil, and moisture contamination.

Clay

You can find a few clay trays on the market in the form of mini pots. Unfortunately, they can be a little heavier to handle.

Metal

you can find good quality reusable metal seed trays. However, opt for rust and corrosion-resistant options, like aluminum and stainless steel. Remember, you will be using them in wet conditions.

Size and Depth

Seed starter kits come in different sizes based on different categories.

Overall size: If you have adequate space, you can choose a larger tray. You can even find multi-level seed starter stations. On the other hand, smaller and more compact options are built for smaller spaces, like window sills.

Cell size: Different kits come with different cell quantities, typically, between 6 and 128 or more cells. If you want to sow more seeds, choose multi-tray options.

For example, the Gardzen 5-Set Garden Propagator Set comprises multiple trays that total 200 cells – so you can sow up to 200 seeds. You will notice that a tray with more cells usually has smaller-sized cells and vice versa.

If you want to transplant your seedlings into a medium to large pot, choose trays with smaller cells to accommodate moderate seedling growth.

Cell depth: Similarly, pay attention to the depth. The longer you want to leave the seedlings in the cell trays, the longer their roots will grow. This means that you want to go for a cell tray with deeper cell depth.

On the other hand, larger cells are ideal for slightly larger seedlings to be transplanted straight into the ground. Nonetheless, the standard size for most cell trays is 1.5 inches long by 1.5 inches wide by 2 inches high per cell. If you are just starting, go for the average number of 10 to 12 cells per tray.

Tip: As a general rule of thumb, go for trays with more cells for vegetable seeds like spinach, kale, or lettuce. This is because these plants usually have a shorter germination and growth period indoors before transplanting. On the other hand, go for trays with fewer cells (no more than 36)for herbs and vegetables, such as tomatoes, peppers, and cucumbers which take longer.

Kit Design

• Drain holes: Choose seed trays with individual cell drain holes for optimal hydration and prevention of overwatering.
• Accessories: Different kits will hold varying accessories. Some may come as complete kits while others will require you to purchase additional tools separately. If you are just getting started, make sure you at least have a seed tray, base tray, and dome. If you want even more convenience and seamless growing, add a grow light and heat mat. If you don’t want to do manual light control, you choose an option with an adjustable controller to automate your process. The Sondiko Seed Starter Tray is a good option.

The Yaungel Seed Starter Tray comes as a complete and all-around seed-growing solution for growers of all levels. The mini greenhouse is best suited for use on the balcony, terrace, or window sills. Moreover, the seed starter kits are specially sized to accommodate flower, vegetable, fruit, and even tobacco seeds.  Nonetheless, the kit’s most prized growth is its heightened dome lid design.

Unlike the standard 2.1-inch height, this kit’s lid extends to a height of 3.3-inch to accommodate more growth and increase the chances of successful transplanting.  The dome lids are designed to fully seal when shut, helping you maintain superior control of the environment. No heat or moisture escapes from the trays when they are securely shut by the lid.

This kit features a 10-pack seed starting tray, with each piece comprising 12 cells.  Along with the 12 growing trays, you also get a humidity dome designed as a heightened lid for each tray, 20 labels, and a mini pointed seedling dibber and widger.  The dibber comes in handy for quickly and easily making holes to sow compost for seeds and also to fill the top of the seed hole. A widger makes it much easier to handle and transfer delicate seedlings and cuttings. 

The seed starting trays are built with optimal functionality in mind, featuring the top transparent cell tray and an opaque green-colored base tray to allow for self-watering. This design also allows for the dual functionality of the kit. You can use the cell tray and base for regular seed starting. Alternatively, you can use the base tray alone to hold peat pellets if you use them as the growing media instead of the cell tray.

On the other hand, the selection of transparent cell trays isn’t random. Instead, using transparent and see-through cells makes it easier to track root growth and development. The growing tray features a standard 10-inch by 20-inch area while the heightened humidity domes are designed with a larger than average growth space. 

On the other hand, you will find an adjustable window at the top of each dome, letting you adjust humidity from 50% to 100%. A drain hole on each cell allows for more personalized hydration and moisture control.

However, the tray alone is not what makes this eco-friendly seed starter kit awesome. It also comes with 16-quart organic coconut coir concentrated seed starting mix made from 100% recycled coconut husks. This allows for lighter and more sustainable growing media.

With a lighter and well-aerated mix, less pressure is put on the seeds, increasing their chances of successful and healthier growth.  In addition to its compatibility with any plant, coco coir promotes nutrient absorption, aeration, and moisture retention – meaning you water the seeds less and you use less water.

Since the coco coir comes in blocks, you simply pull out what you need for the cell trays. Remember, coconut coir, like peat, expands when water is added. So, you need very little for each cell. And the best part? When you pop the seedlings growing in the coco coir out, you transfer them into the garden beds, pots, or containers as they are. With this kit, all you need is the seeds, water, and light to start growing your favorite plants!
