A Complete Buying Guide to a High-Quality Seed Tray

Seed trays make the process of growing seedlings a whole lot easier. Although it may seem like a simple task to buy a few little seed-starting pots, you will soon discover that there are many different types to choose from. Buying the best-suited seed trays for your seedlings will ensure they grow healthily and quickly. In this guide, we outline everything you need to consider when choosing the best seed trays to start your dream garden.

Advantages of Using Seeds Trays

  1. Using a variety of containers to start germinating seeds can be messy, labor-intensive, and take up a lot of space. Seed trays hold neat rows of seedlings together, making them quick to plant and easy to move
  2. Evenly watering or heating the soil of different seed containers can be time-consuming, while compact seed trays make the process of evenly watering and heating the seeds fast and simple
  3. Drainage holes at the bottom of seed trays with individual cells help to maintain better soil moisture level, as excess water drains out. At the same time, these trays use a base tray to catch excess water and allow the germination of seeds by gradually soaking them from underneath
  4. Using seed starting trays makes it easy to move whole groups of seedlings at once instead of individually having to move each pot. Whether you need to move your seedlings outdoors or under grow lights indoors, you can easily move 50 or more plants at once

Factors To Consider When Choosing Seed Trays

Seed tray size

Some seed trays with cells can hold up to 70 seedlings while others have only 6 cells. The size you choose will depend on what you are planting, where you are keeping your plants, and how many seedlings you plan to work with. If you have a small greenhouse with plenty of space for your seedlings, a big tray is a good idea. If you want to keep your seedlings on the windowsill in your home, opt for a smaller tray.

Seed tray materials and construction

Seed starting trays are either made of plastic, which is reusable or they are made from a biodegradable material such as peat which is generally not used more than once.

Both types of trays work well to grow seedlings. The tray material you choose may depend on a few different factors.

Plastic trays

If you are an avid gardener and use trays every season, it will be more cost-effective to get reusable trays. The thicker the tray, the more durable it is, however, it is also harder to remove the seedlings from a plastic tray for transplanting.

If you are reusing your trays keep in mind that you will need to clean them and have some storage space to keep them where they won’t get damaged.

Organic veggie gardeners should opt for BPA-free polypropylene plastic seed trays that will not leach chemicals into the planting soil.

Some plastic trays are very thin and intended for one or two uses only. As they are thin, they are easy to manipulate, allowing you to remove the seedlings from the tray without much effort. However, in doing this, you will also likely break them. These types of trays are generally meant to be thrown away after the first or second use, which might not bother you since they are inexpensive. However, plastic waste is not great for the environment.

Biodegradable trays

Biodegradable trays cost more, but they offer many benefits when it comes to the health of your seedlings and the environment. When your seedlings are ready to be transplanted outdoors in your garden, there is no need to remove them from the pots. Simply place the whole pot with the plant in the soil. The pot will break down naturally over time and the roots will spread into the ground. This prevents any transplant shock, stem damage, and root disturbance during the replanting stage. It also makes the entire process less messy and much quicker.

Seed Tray Accessories

Check whether your seed tray purchase includes any of these items. You can choose a kit that includes all the extra items or buy what you need separately.

Dome lid

Some seed trays come with a dome lid. This clear plastic lid allows you to control the temperature and creates a humid environment ideal for seed germination. Domes will either be solid or have adjustable vents to allow humidity control. If you purchase a dome separately, make sure it matches the size of your seedling tray so that it seals around the edges.

Base tray

Base trays are fairly flat with no cell structure and are used to keep cell trays organized. Placing your cell tray in the base tray allows you to catch drainage water from the cells and also allows you to water seedlings from underneath to reduce pest and disease problems. Base trays can also be used for hydroponic growing, wheatgrass, microgreens, and help keep things clean.

Watering mat

Watering mats can be used to draw water to the seed tray cells without oversaturating the soil mix.

Heating mat

Heating mats are usually purchased separately and don’t come with a seed starting kit. They are a great accessory for early indoor growing since they increase germination and growth rates by providing the ideal temperature.

Labels

Don’t forget what you have planted. Labeling your seedlings might be necessary, especially if you are new to gardening and not yet proficient at differentiating all your seedlings by just looking at them.

People Also Asked

A: The length of time will depend on the size of the tray cells. As soon as you see roots growing out of a jiffy pellet or coir pot you need to transplant them. As a rough guide, a 12-cell tray can keep seedlings up to 10 weeks while 72-cell trays will only be big enough for two to three weeks.

A: The best way to remove seedlings is to turn them over in your hand and softly push or tap the bottom of the tray to loosen the soil and roots so it slides out in one piece. Trying to tip over a solid 48-cell tray will most likely damage the seedlings. Never pull the seedling by the stem. If the roots seem stuck to the cell tray, slide a popsicle stick or butter knife gently around the edges to loosen and tip the cell over.

A: This may depend on the type of plant. Generally speaking the optimal temperature for growing seedlings is between 65°F and 75°F.

How To Germinate & Plant Cannabis Seeds – Cybele Labs

So you want to start growing cannabis, huh? Great! Where do you start? What do you need? How do you have a successful germination rate?

If reading is not your thing, check out our video tutorial on YouTube. Let’s get right into it!

How To Germinate Cannabis Seeds

Things you’ll need

  1. Your favourite cannabis seeds
  2. Glass of tap water (any container works)
  3. Paper towel
  4. Tupperware container

Get yourself a glass and fill it with water, tap water is perfectly fine. Drop your seeds in and place the glass in a dark space like a cabinet or cupboard and check back in 12 hours. Make sure its a dark spot so you can restrict all light, this will allow your seeds to germinate properly. If you have multiple different seeds (strains) be sure to label each glass and separate them accordingly.

Now once you come back you’ll notice most of the seeds have sunk to the bottom of the glass, If you see some floaters, give them a poke and they should drop to the bottom. Back into the dark space for another 12 hours.

At this point your seeds will begin to crack open and you’ll notice a small white spot, this is the beginning of a tap root. Now you’re ready for the next step, get some paper towel and dump the water plus seeds onto the paper towel to soak it completely. Reposition your seeds so they’re evenly spaced and fold the paper towel over, ensure the seeds have full contact with the soaking wet paper towel. At this point you can place the paper towel into a tupperware container and put it back into a dark spot for 12 – 24 hours.

After 12 – 24 hours you will see a tap root approximately 5 millimetres long, your cannabis seeds are now ready to be planted in a growing medium of your choice! We used soil in this tutorial.

How To Plant Cannabis Seeds

Things you’ll need

  1. Your germinated cannabis seeds
  2. Small pots or a seed starting tray
  3. Your favourite seed starting mix
  4. Toothpick
  5. Spray bottle filled with warm water
  6. Dome or plastic cover
  7. Heating pad (optional)

Fill your starting tray with a seed starting mix and gently pack the soil down with your finger. Use a toothpick to poke a 1inch hole directly in the centre of each pot and then place each seed, tap root down into the hole. This will allow the tap root to shoot down into the soil and anchor itself, don’t burry the seed, make sure it’s completely visible.

Spray each individual pot with warm water and cover the pots with a plastic dome or plastic cover. Now the goal is to have your germinated seeds anchor into the soil and shoot straight up which is the beginning of your cannabis plants stem. Cover the dome with a blanket or towel and use a heating pad to help speed up the process, this is totally optional. Check back in 24 hours, throw the pots under some grow lights and boom, you’re on the way to growing some cannabis.
