Grow Seeds Without Soil!

Introduction: Grow Seeds Without Soil!

Oh the places they’ll grow! Whether you want to eat them, grow them, or throw them in a maraca, seeds are nature’s suitcases of magic. From the smallest orchid seed at 1/35,000,000th of an ounce to the largest coconut seed at just under forty pounds, seeds are food, culture, and ultimately, life. So let’s grow some, yah?

If you want to check out seeds in action with a classroom or at home, you don’t even need soil to go about it. With this extraordinarily simple process, your seeds will start sprout without a doubt. This is great for the youth gardener who is learning seed anatomy for the first time or the avid gardener testing seeds for viability. Let’s grow!

  • What: Seeds in a Bottle
  • When: Now! And over the course of a couple weeks. 🙂
  • Concepts: biology, plant life, seeds, germination, life cycle
  • Materials:
    • Seeds (we used scarlet runner beans, but smaller seeds are excellent, too)
    • Paper towel
    • Bottle with cap (or a zip-loc bag if you need)
    • Water
  • Tools:
    • This seed anatomy guide for reference

Let’s seed what’s next!

Step 1: Soak Your Paper

Give your paper towel a quick dip so that it is moist throughout but not soaking.

Step 2: Tuck in Your Seeds

Fold your seeds in to the paper towel, so that they have a little space between them. For smaller seeds, you can leave less space between each one.

Step 3: Bottle It Up and Place!

Take your folded up seeds and put them into a bottle, and close the cap. This will keep all the moisture in, and your seeds happy. If you don’t have a bottle, you can do the same with a very well-sealed zip-loc bag. Leave them in a warm place somewhere where you won’t forget them.

Step 4: Unveil Your Seeds!

So simple! You can start to see progress usually after only a couple days. The water from the towel starts to break down the seed coat, and makes the nutrients in the endosperm accessible to the “baby” plant. First out of the seed is the embryonic root called the radicle, and this will push its way to becoming the first main root. As you can see in the fifth photo, other roots may begin branching off.

For reference, this is a great image of seed anatomy, and this is a great video explaining seed growth.

You can either dissect them to see the tiny plumules (baby leaves), or now transfer them to soil, to see the seed rise up, and release the first two leaves.

Regardless of what you choose, you just started seeds with no soil! I would love to hear what you’ve figured out with starting your seeds. Comment below if you’re growing your own!

Have fun and keep exploring!

Germination Cannabis Seeds

You bought beautiful Premium Pro Seeds from Suzy Seeds and of course, you want to get started. First, you have to germinate the seeds. Below, I will discuss my favorite way extensively, but also suggest other good methods. Suzy Seeds exclusively sells feminized cannabis seeds, so you don’t need to remove male plants, which applies also to autoflower cannabis seeds. It’s good to know that a cannabis seed does not need light to germinate. What is important, though, is a humid environment and an ambient temperature of around 20 °C. In general, there are three ways to germinate cannabis seeds: – In a cup of water – On a damp surface – In soil. My favorite way to germinate the seeds is to put them in a cup of water and then between a damp paper towel. This goes well in 99% of the cases. How long does it take cannabis seeds to germinate in general? Or how do we germinate autoflowering seeds? The time depends on the strain or type of seed, but autoflowering seeds germinate in the same way and time as feminized or regular cannabis seeds. That is why I will more extensively describe this first way.

We recommend not to touch the seeds or the seedlings with your hands. If you do anyways, make sure your hands are clean and if possible use plastic gloves.

Suzy’s favourite germination method

Maintain an ambient temperature between 20 and 25 °C, otherwise, the seeds will not or at least not optimally germinate. Fill a cup with water and put the cannabis seeds in it. Get the seeds out of the water after 12 to 24 hours and spread them on a plate between two layers of damp paper towel. Put the plate in a dark and enclosed place. It’s important to make sure that the paper towel remains damp. I moisten the paper towel every 6 to 12 hours. Do not use too much water. The seeds only need to be damp. Within 48 to 72 hours, the seeds should pop open. But be patient, because it can take longer (6 days at the most). When the root becomes visible (the white sprouts as you can see on the picture above), you need to plant the germinated seeds. If you do not plant them in due time, the root can be damaged.

Suzy’s Tip: Try your germintion method on a couple of seeds (maximum 3). This way, you can test if your method works well. Often a wrong germinating method is used and the seeds don’t germinate. Do you want to germinate your seeds in a different way? Continue reading.

Germinating cannabis seeds in a cup of water

Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Fill a cup with water and put the cannabis seeds in it. After 3 to 5 days, the seeds should pop open and a tiny root should come out. As soon as the sprout is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Planting the germinated seed has to be done with lots of care and attention. Put them 0.5 to 1 cm in the soil with the root down. This way, the root (the white sprout) will more easily grow downwards.

Germinating cannabis seeds on a damp surface

Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Put the cannabis seeds on a surface that holds moisture, like wadding, paper towel or tissues on a saucer. Moisten the surface well, but avoid making it too wet. The moisture evaporates quickly at room temperature, so check during the period that the seeds will germinate if the surface is still damp enough. You can also cover the seeds with damp wadding or tissues and another saucer on top. Because of the moisture that gets into the seeds, they are activated and start to germinate. As soon as the germ is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Put them 0.5 to 1 cm in the soil with the root down. This way, the root will more easily grow downwards.

Germinating cannabis seeds in soil/compost

Direct germination of marijuana seeds in the soil is a commonly used method. You don’t have to handle the fragile plant, so it is not disturbed in its growth process. However, the chances that the seeds will germinate are lower than when applying the other methods. When using this method, it is important to use good soil. You can inform yourself about the different types of soil at your local grow shop. Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or not optimally germinate. Put the cannabis seed about 1 cm deep in the soil. Cover the hole with some soil and gently press. The soil needs to be light so that the plant can easily grow to the surface. Solid soil is hard to penetrate for the roots and will cause a delay. The seeds will germinate under the ground and will come to the surface after 4 to 10 days.

There are few ways to germinate cannabis seeds: In a cup of water, on a damp surface, In soil. My favorite way to germinate the seeds is to put them in a cup of water.
