how to plant a marijuana seed in a cup

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.

– 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 on a damp surface

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.

Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Use a clean room and area for the germination process. 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.

– In a cup of water

– In soil

2-3 gallon container

I think it’s a matter of preference. Just as a quick summary: It’s easy to give too much or too little water to a very small seedling in a big pot. With a solo cup, you just soak the grow medium and the roots get a lot of both oxygen and water at all times because the medium dries out quickly. The downside is you have to transplant a seedling as soon as the leaves reach the edges of the cup, or its growth starts slowing down. Also, if you’re not careful you could possibly shock the plant during transplant.

Instead of pulling the whole plant out of the container, sometimes you can just cut away the solo cup when you plan on transplanting. This is one of the advantages of starting in disposable cups – it makes transplanting easy and stress-free. You can also gently run a butter knife around the outside to help loosen the soil, turn it upside down and pat out the seedling, soil and all!

Add your potting mix to the solo cup. Dig a small hole about 1-2″ deep and gently place your sprouted seed, root down, into the hole you made. Lightly fill around and cover with soil. You’ll see a seedling emerge a day or two later!

If you start seedlings in a solo cup, you should try to transplant to a bigger pot around the time the leaves reach the edges of the cup. This seedling is ready for transfer!

The truth is, your seedlings will thrive whether you start in a big or small container as long as you take good care of them! Neither way is the “best” method; it’s more a matter of personal preference.

Go Bigger If You Need to Spend Time Away From Your Cannabis!

So, you’ve decided to grow your own cannabis plants. You purchased a pack of seeds, assembled cultivation materials, cleared a space in your garden, and are ready to grow your first cannabis crop . With everything in hand, it’s time to begin the very first step of cannabis cultivation : germinating seeds.

To employ water germination, fill a glass with tap water and let it sit until it reaches room temperature or around 65 degrees Fahrenheit. Add two to three plant seeds per cup and allow them to sit, watching for any changes. Change the water to fresh tap water every two days, making sure it stays at room temperature.

What is germination?

When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth.

When the seedling stems reach two to four inches in height, it’s time to transplant your cannabis into larger pots with more room for roots to spread down and out. After you’ve done this, you’ve successfully germinated your cannabis seeds into proper, young plants.

The downside of water germination is that once they’ve popped, you’ll need to maneuver them into their growing medium manually. This is a delicate process, as germinating seeds are extra fragile, and any harm risks the development of your plants. Make sure to place the seed roots down in the soil when you transfer to a pot.
