Home-produced weed is tastier, healthier and of course a lot more fun. But did you also know that it’s extremely simple? If you want to make CBD oil or weed oil yourself then cultivating the raw material is an important step. Even if you don’t have green fingers, just follow this step-by-step plan to be able to make CBD oil from your own crop in a few short months.

Cultivating weed yourself

In the first article we touched on the legal issues. It’s not legal to grow your own weed but it is tolerated. You can read what exactly that means for you in part 1 of this series. 

In this blog series:

  1. Part 1: Everything you need to know before cultivating weed yourself
  2. Part 2: 7 reasons why it’s better to cultivate your own weed

Let’s order some weed seeds and get them to germinate!

Step 1: Which Weed is For Me?

Because there are hundreds of different varieties it can be hard making a choice. The secret to the right choice lies in asking the right questions. We will assume that you have never cultivated weed before. And to make it easier, we have already made some choices for you.

Will you go for a so-called autoflower weed variety? Then you are opting for convenience. In due course these plants flower on their own which makes cultivating weed as easy as cultivating strawberries. Then to keep it simple we opt for growing weed in the garden and limit these choices to plants which don’t get any higher than your fence (1.8 metres). We do that to avoid possible problems.

Different plants have different effects. We cannot comment on medical use. You know your objective best yourself.

CBD-rich varieties in which the CBD percentage is higher than the THC percentage are really good for keeping a clear head after you take them. Have you set your mind on the physical effects of THC? In that case choose a variety which has a higher THC percentage and is known to produce a physical stoned effect. Prefer a broad smile to a narcotic feeling? Then the right choice is a variety with a clear mental effect.

THC (physical effect): Auto Northern Light

THC (mental effect): Auto Amnesia Haze


The above links take you to our partner Dutch Headshop where you can choose from a wide range of weed seeds.

As long as you follow the next step carefully, all the seeds will probably germinate. And where possible, we choose house brand seeds from our partner Dutch Headshop because with those you get supplied with a free germination kit. 

Step 2: Germinating Weed Seeds

Super! Your seeds have arrived. Before you excitedly put the seeds in the ground, it’s important to germinate them. That ensures that the first root is strong and growing downwards nicely.

If you’ve taken our advice and ordered special autoflower seeds, then the exact time of germination doesn’t matter that much. You can start germination from the end of April.

With an order for Dutch Headshop house brand weed seeds you get a plastic tray that contains a couple of cotton pads. The idea is that you place all the seeds between the pads and sprinkle them with spring water (e.g. Spa, non-carbonated). Keep the water at room temperature and not in the fridge.

A few drops of water is enough. Close the tray and put it preferably in a dark, warm place. That might sound crazy but seeds do germinate under the ground where there is no light. Sunlight can scorch the sensitive root.

During germination, do not:

  • Put the seeds in a glass of water.
  • Use (warm) tap water in place of spring water.
  • Put the germination kit in the full sun on the window sill.
  • Allow a pool of water to lay in the germination kit. A few drops is enough.

Wait at least 24 hours before looking again. Not all the seeds will germinate at the same time. It can take up to a week before all the seeds have developed a root. Check the tray each day at around the same time. As soon as you can see a root at least a centimetre in length, carefully pick up the seed with tweezers and plant the seed one centimetre deep in the soil. For best results do that in a small tray placed on the window sill.

Step 3: Allowing the Seedling to Grow

Your seedlings are in the soil! Congratulations! The first leaves can appear within a week of germination. First two leaves, and then another two. Your young plants will get enough nutrition from the seed to produce a further six or so leaves. After that, weed seeds mostly derive their nutrition from the environment. Rich soil with compost is good enough to grow the plant until the mature leaves start to appear. Weed plant seedling

Give your young plants a small amount of water every day. As soon as your plants have more than six leaves set them out in the open ground and in full sun. This can last from one to three weeks.

Step 4: Making the Weed Plant Big and Strong (Growth)

Before the plant begins to flower and produce weed, it’s important that it has a sturdy skeleton. As you’re growing it outside in the open ground, it will look after itself to a reasonable extent. But plants don’t drink only water. Nutrition is also vitally important for your plant. Choose organic fertilizer from Plagron at our partner Dutch Headshop and give your weed plant the feed it’s calling out for. Give it a bit of water every day with a thimble full of feed and before long you will have a sturdy plant capable of bearing heavy flowers.

Autoflower weed plants develop seamlessly into the flowering phase. It can take three to six weeks before you see the first signs of the flowers setting. 

Step 5: Cultivating Big Flowers (Buds)

Your plant has now reached the flowering period. During this exciting time, your objective is to increase the yield. Whatever else you do, this means giving a bit of water each day with a miniscule amount of plant feed.

It can take six to twelve weeks from the start of flowering before your plant is ready for harvesting. But how do you know when it’s time to harvest?

Step 6: Ready for the Harvest?

Examine the flowers carefully. Close up. Use a magnifying glass or a special microscope.

Trichomes on a weed plant

Resin glands grow on other plants besides weed. They look just the same on weed. When a weed plant is ripe for harvesting, you can tell by the colour. They are amber in colour.

These are the resin glands or trichomes of the weed plant. These glands produce a sticky substance which smells sweet and spicy. This is what gives weed its characteristic smell. The longer the plant is in flower, the more these resin glands gain in colour from transparent to amber. The technique is to harvest your weed when most of the resin glands have just turned from transparent to a milky-white colour. It doesn’t matter if the colouration is not the same all over.

Step 7: Harvesting Weed

The part which you want to harvest is the flower on which most of the sticky resin is sitting. But for making weed oil or CBD oil, it’s a good idea to also use the leaves from around the flower.

Trim away the large bracts around the plant. Snip the branches to which the flowers are attached off the plant.

Step 8: Drying Weed

Your harvest is almost ready! Just another week or two of drying in the shed or the attic and then your home-produced weed will be ready to use. Drying is an important step because fresh weed contains a lot of moisture. And it has consequences for the composition when you use your harvest.

Step 9: Storing Weed

After drying the weed you might not have time to immediately make weed oil. In that case it’s a good idea to store your weed in an airtight manner. Are you storing it for no more than a week? Then you don’t need to take any special measures and can store the harvest in any kind of Tupperware box. Do you want to store it for longer> In that case use a vacuum container from TightVac. With these jars the air is removed from the container enabling your harvest to be stored for a long time odour-free.

 In a subsequent article we will explain step-by-step how you can make your own weed oil.

Some varieties of weed don’t need green fingers at all.

Next Step: Making Weed Oil Yourself!

The months fly by when you’re growing a weed plant. But we want to say again, for the sake of completeness, that cultivating weed is not legal everywhere. So always have regard to the law in the particular country where you want to grow it. As far as the Netherlands goes: If you stay small-scale and cultivate no more than 5 weed plants for your own use then growing your own weed is tolerated. That is to say, if you don’t cause any bother you won’t get prosecuted. You also have to voluntarily get rid of your plants if you are checked.

Once harvested, you have the means to make your own oil at home. You don’t call that CBD oil, but weed oil. It’s your choice as to whether there is a lot of CBD or THC in your oil. And that’s exactly what makes cultivating your own weed so satisfying.

In the next and final article of the series we show you step-by-step how to make weed oil yourself from your own harvest using a Cannolator.
