Hydroponic Seeds Canada Beginning Guide

Hydroponic Seeds Canada Beginning Guide

Hydroponic Seeds CanadaDo you want to grow your own food, but don’t know where to start? Do you want to reduce the cost of growing plants from seedlings in the store?

If so, then growing seedlings on hydroponics is the best way for you to do both. Hydroponics is an easy and affordable way for those who have little money or space.

You can grow many vegetables without soil before they turn into mature plants ready for harvest with the help of hydroponic gardening. They grow healthier because their nutrients come directly from the nutrient solution, rather than being absorbed from the soil.

This blog post will explain why starting with your own seeds is better than buying them in a store, what equipment you need, how to germinate them and how to transplant them into pots.

Why are seeds better than seeds from the store?

Starting hydroponic plants is cheaper and does not take up much space, because they turn into mature plants faster.

When you start growing hydroponics seeds, you can choose the varieties and types of plants that will grow best in your growing room, rather than buying seeds from a store. And most importantly, starting seeds mean healthy plants.

One of the main advantages of hydroponics is absolute control over your growing environment. The quality of seedlings bought in the store varies greatly. Fruit and vegetable seedlings from the grocery store are usually grown in sterile, unnatural conditions, where they do not have to fight pests or diseases.

The initial stage is very important, and you need to pay attention to what is possible and what is not, which will help keep your plants healthy.

what equipment do you need to start sowing seeds for hydroponics?

When you start seeds in a hydroponic way, the ta plant must meet these basic needs: water, light, nutrients, and rest conditions. You run the seeds on a system different from the real hydroponic system.

1. intermediate start

Although there are several types of nutrient media that you can use to grow seeds, it’s worth trying them out to see how they work in your indoor garden.

coconut coir

Coconut coir is a hydroponic medium, it’s a material that can hold water, so you don’t have to worry about over- or under-watering. Coconut coir is one of the best options for those who are looking for something sustainable and organic. It is very light and porous and helps prevent mold growth, which means less chemicals are needed!

Stone wool cube

Stone wool cubes work well with a closed starter system with a large air flow around the roots.

They come with pre-drilled holes, and they have enough space for young roots to develop before transplanting into a larger container. They also provide excellent drainage so that excess moisture does not accumulate over the nutrient medium, which leads to root rot.

starter plugs

Starter plugs take up less space than stone wool cubes, but they make an excellent material. The advantage of using starter plugs is that the starter cubes are sterile, and they do not need to be soaked in water before use. For hydroponic seed sowing, make sure that you use starter plugs with a pH of approximately neutral (pH = about) or higher.

Starter plugs without nutrients will have a higher pH range than those containing fertilizers because the plant absorbs more from the environment when it begins to grow as a seedling. They also dry out faster, which is perfect to keep the starter on hand for immediate planting!

2. Netcups

Clean cups are also used by many people. Using clean cups when hydroponically sowing seeds, they become sterile. They do not need to be soaked in water before starting work. Clean cups are provided with labels for the convenience of planting at a depth, which is useful for hydroponics seed sowing.

3. container / train

Since you can plant a large number of seeds, it is better to look for trays and boxes in which these individual cups will fit and in which water will be stored. Look for containers 4 to 6 inches deep for the best results!

4. humidity dome

The humidification dome is necessary for hydroponic seed sowing. The humidifier must be placed on a flat surface at least 12 inches away from the pan and provide sufficient air flow.

For best results, look for a humidity dome with at least two vents on each side. This will allow air to circulate and make your early seeds hydroponically happy!

There should also be enough space between the towers so that they do not touch or overlap each other; otherwise, early seedlings may be damaged due to lack of airflow.

5. heating mat

Heating mats provide warmth and moisture during the germination process, ensuring the appearance of good, healthy young shoots! The heating mat will help compensate for the low temperatures of your air conditioner in winter, providing a warm environment for the plants on it!

6. grow lamps

Growing lamps provide ideal conditions that help seeds germinate indoors. They have many different types:

  • HID Grow Lights (high intensity discharge) are lamps for growing with a large range of spectrum. HID is recommended if you plan to germinate plants in a vegetative state (i.e. HID). grow without flowering) because it provides a better spectral range than other early hardware.
  • LED lighting, energy-efficient light with lower heat dissipation than in any other plant growing technology. LEDs may be preferable if you want to bloom on your plants early.
  • fluorescent lamps, cheap, but not as effective as HID or LED, because they emit not enough light in the blue range of the light spectrum
  • CFL (compact fluorescent lamps), a variety of inexpensive light sources with red and green wavelengths suitable for sowing seeds – no additional additives are required!

7. chemicals to raise or lower the pH level

PH regulation is the only way to control your nutrient balance. When sowing seeds in an environment with a high pH level, it may be necessary to add an acid such as phosphoric or nitric acid (in small amounts) to balance the PH.

Adding too many chemicals will lead to the accumulation of salts, so it is important to use only what you need and not overdo it with the application of the solution.

seed germination using rock wool

Now let’s start sowing it!

here are step-by-step instructions for planting seeds for hydroponics:

Step 1: Preparation of the initial seed medium:

There are several important points when searching for seed containers.

First, it’s the size of the container. It should be large enough to place the soaked cube for further plant growth.

It can be difficult for seeds to germinate young plants if they are constantly flooded with excess water. The seed should be at such a height that the water can come into contact with the cube and the seed, providing air circulation from above.

To start growing hydroponics seeds at an early stage, you can use filtered tap water or purified water. As soon as you have water in the container for germination, it is important to conduct a test to make sure that the pH level is in a certain range.

Some manufacturers recommend adding a half-strength solution or a solution with a lower nutrient content to the seeds at this stage. However, if they have never been grown on hydroponics before (if they were watered only from a glass), just plain water should be added.

Check the pH of your water with a pH level test and reduce it to 5.5 – 6 with a liquid solution. If it is higher than this value, never go below 5.5, as this may damage the rock wool.

Put the starter cubes in a container with water and leave to infuse for an hour so that they are absorbed. Cubes are great for growing on hydroponics, as they maintain a perfect balance of moisture and air. But if you squeeze them too hard, they will deform. Cubes can stay wet for several days without adding water, so be careful.

Do not waste water if you pre-soak the cubes in water with a balanced pH before transferring them to another tray. Instead, please store in a closed bucket.

Step 2: Planting seeds in cubes

You can buy a cube with a hole in it and use it, or make a hole in the top of your cube to a depth of, but not more than an inch.

Now all you have to do is take a few seeds and carefully place them in the hole. They won’t fall off, so use a finger or something else that doesn’t exert pressure to insert them tightly into the hole. When you’re done, you can press a small piece of rock wool over the seeds to cover them.

The first thing you should do is close the container. This can be done with an inverted tray of the same size or something that can stand on the tray without pushing the cube. This will create a dark environment, which is necessary for successful hydroponic germination.

The container in which you will sow the seeds should have a temperature of 68 degrees Fahrenheit. If the growing conditions in the nursery are lower, a heating pad can help keep your tray warm.

Step 3: Check the water level

It is best to check the water level every day after starting to plant seeds in rock wool. Seeds grown in this environment do not require watering during the hydroponic germination period. Use the water accumulated in the first stage only to keep them moist as the level decreases.

It is recommended not to add nutrients at this stage, because the sprouts become stronger and need them only after they are in your hydroponic system.

When you start germinating hydroponic seeds, there is a high probability that more than one seed will germinate in individual wells. No matter how tempting it may seem, please do not give in to the desire to transplant only slightly, as pulling out the roots of seedlings can also damage other shoots and their root growth.

After 3-4 days, the first real leaves will appear. When this happens, carefully select the smaller of the two growing shoots and cut the smaller one right above the cube.

Step 4: exposure to sunlight / light

When planting seeds, it is very important to have a working light source for the plant. Planting in a place with sunlight will help the seeds germinate without much difficulty, because they get this material from their natural environment. However, sometimes you will rotate the tray so as not to lean towards the light when using the window.

Three hours a day should be sufficient when using sunlight and five when using artificial lighting sources such as fluorescent lamps. Once your seedlings grow up, they may need up to 15 hours of light a day.

This is where the main drawback of the window should be used-the lack of natural light. Without enough sunlight, plants can fall off or become too weak to stay on their feet, which worsens if they are not caught early.

Hanging lamps for growing plants solve this problem by providing a full rate of natural light for 15 hours a day. Since they are overhead, the plant will never tilt to the side. In addition, these plants will grow stronger and healthier thanks to full access to light.

It should be noted that seedlings will also need time in the dark, so you should have enough darkness for them when they get their norm.

The last (big) precaution is to make sure that all the growing lamps are located far enough from the top of the seedlings so as not to burn them (depending on the type of lighting).

As they grow, you should raise your growing lamps. Water consumption may increase slightly as the plants get bigger and healthier, as well as with the release of heat from your lighting fixtures.

Step 5: Transplant

The seeds germinate for 2-3 weeks until they can be planted in your hydroponic system. To avoid waiting, you can check at the bottom of the ROCKWOOL starter stone and transplant when the plant has roots that begin to protrude through the bottom. This is a good sign, because the plant can get its roots stuck in its already wet cube if left too long.

You can free up space in your hydroponic system for seedlings by moving the stone wool cubes along with the entire plant into the nutrient medium. Cover lightly and carry out top watering for several days.

This may seem like a simple task, but plants are prone to transplant shock at this stage. Not only because the pressure is removed from the growing tray, but also because of the transition to a new environment. They will need time to recover from the initial shock.

When transplanting sprouted seeds to hydroponics, do it at the right time. You can put them in a hydroponic system and remove the original heat-sensitive cubes from them for growing, if they shrink slightly in size and are ready for watering.

why didn’t all my seeds survive?

There are many reasons why not all seedlings will survive, and not everything can be explained. But, depending on the plant, there are temperature differences that need to be taken into account.

If you have plants for seedlings in cold and warm weather in the same environment, this may be too much temperature fluctuation for both types of plants.

Other things you need to know about are as follows:

    • prepare everything that you need for planting before taking seeds or planting from the cold storage
    • drying medium – seeds germinate when placed in a warm, humid environment. If they dry out between watering, it can kill them or prevent germination.
    • maintaining high humidity is very important. A humidifier or simply an inverted tray mounted on top of the growing tray will help retain moisture. Transparent domes can also be useful in lighting.
    • do not pour water over and do not allow the mineral wool stones to become too wet, as this may cause the seeds to rot before they have a chance to germinate properly. Once the seeds germinate, you can spray them inside the growing tray instead of pouring water.
    • do not overfeed – you should start feeding with nutrients only when you see the first set of real leaves. The EC of your water should be a maximum of 0.8-1.2. In the early stages of life, plants will receive all their nutrients from cotyledons. Only if these first real leaves show that they are becoming dependent on external sources of nutrients or fertilizers.
    • proper feeding – it is important to feed only when you see the first set of real leaves or until the final water level is from 0.8 to 1.2.
