How To Grow Hemp Plants At Home

I see so many CBD products all over the internet. Most of the high-quality CBD products are costly. It made me wonder if I can make my own CBD products from hemp seeds. I did some research to find out how to grow my own hemp plants for personal use.

It is possible to make your own CBD products, but it depends on how you want to do this. If you want to do this from hemp seeds, you first need to plant hemp seeds in the soil. After 8–11 weeks you can harvest the crop from the hemp plants and make your own CBD product. Keep on reading if you want to find out how to grow your own hemp or cannabis.

Space

If you are planning to grow between one and five plants inside, then probably your garage would be big enough (or any other space that is big enough). 

Keep in mind that a hemp plant can grow very tall so it requires space when you want to plant hemp in your home. If you are planning to grow your hemp plant in your garden, the plant can even grow to up to 16 feet! If the plant has the exact right growing conditions, it can even grow three inches per day! 

Make sure to space the plants 12 inches apart from each other. A good rule of thumb is the bigger the plant can get, the further it needs to be spaced away from each other. If you are planting hemp for seed production, the plants should be closer to each other. 

The recommended spacing with seed production is around 7 inches. This encourages the plant to branch. 

Like I mentioned above, there are a lot of different hemp plants available on the market, and each one of them has its own characteristics. 

We talk about the different hemp seeds later on in this article, for now just remember to choose the right hemp seeds that have the characteristic you want them to have.

In a study of growing hemp, researchers planted hemp plants with different spacing from each other. The results show that the wider the spacing was, the higher and heavier the plant becomes.

Strong light

Light is one of the most important things needed for growing high-quality hemp.

Light play key roles in growing hemp and ensuring the quality of the hemp. Light plays key roles in flowering, controlling yield, sex of the plants, and the cannabidiol (CBD) and tetrahydrocannabinol (THC) concentrations in the hemp or cannabis plant. 

There are a lot of factors within the light that is playing a big role for the hemp plant, for example, photoperiod, light quality, and light intensity. 

The photoperiod means the time that a plant is exposed to light in a 24 hours cycle. 

For hemp, flowering occurs when the duration of light and temperature changes. That’s why you must plant the seed at the right moment in the season so that the flowering process start exactly on time, and not too late or too early. 

Cannabis sativa, for example, is a short-day plant. This short day plant will change from the growth stage to the floral growth stage when they are exposed to short day lengths, in the case of the Cannabis sativa, this is 12 hours of light to trigger the flowering. 

When growing the plant inside its recommended to give the hemp or cannabis plant between 16 and 18 hours of light in the growing stage.

When growing hemp inside, you can control this with LED lights. If you are using LED lights, just make sure you keep the light 18 inches (45 cm) away from the top of the plant. 

Another thing to keep in mind is to use full-spectrum light, this will ensure that the plants will not become vulnerable to nutrient insufficiency.

What kind of soil do I need?

With the soil, you need to be cautious. Hemp prefers a soil that contains a soil pH of 7.0–7.5. Soil that drains poorly or is structured poorly will most of the time result in crop failure. That is something that you definitely not want! 

Hemp just doesn’t grow well in wet soils. The problem with wet soils is that it restricts root and shots growth. 

When growing hemp inside you can buy several soils from different brands that ensure your hemp plant will grow and produces good quality crops. 

If you want to use normal garden soil, then also add grit to it (sand, vermiculite, pebbles, or perlite), this will create the perfect growing soil for your hemp or cannabis plant. 

And like I said before, also look out for the correct pH value when buying gardening soil.

When growing hemp indoors you will need some kind of medium where the plant can grow in. If you are growing indoors, you will need a 10-gallon (40 liters) pot. This ensures the roots can grow and that your plant will produce high-quality crops after 8–11 weeks. 

If you are planning to grow outdoor, it’s a good idea to first test your soil to check if it has the right soil structure and also a good pH value. If that is not the case for you then organic fertilizer is recommended. A nitrogen-rich fertilizer can be applied to the soil in a solid or liquid format.

A solid feed can be applied once and left for about a month. Most solid feeds break down slowly, and the plant has enough time to absorb it. Another benefit of solid fertilizer is that it lowers the risk of chemical burns because of its slow absorption. 

Once pre-flowering begins, a more phosphorus-rich fertilizer is recommended to promote flower growth.

Do I need nutrition?

Good question, and the short answer is that it depends. When growing indoors on a small scale, it is unnecessary if you have bought good soil. 

Although it isn’t necessary,  still it’s recommended. The hemp and cannabis plant needs a variety of mineral nutrients and non-mineral nutrients to grow healthy. If the plant does not receive enough of these nutritions, it will cause unhealthy growth, lower quality of the crop, and even a complete failure of growing the crop. 

Mineral nutrients obtained from the soil are:

  • Nitrogen (N)
  • Phosphorus (P)
  • Potassium (K)
  • Calcium
  • Magnesium
  • Sulfur

Non-mineral elements derived from air and water are:

  • Carbon
  • Hydrogen
  • Oxygen

How much nutrition should I give the hemp/cannabis plant?

This really depends on the growing stage where the plant is in. Each stage of the plant requires slightly different nutrients. 

Seedling phase:

If you are growing your hemp plants inside in a pot that has no natural nutrients, you could use root boosters and seedling nutrition. 

Be careful though, if you don’t use a fertilizer that is not specifically produced for cannabis or hemp, there is a high chance the fertilizer is too strong if that is the case you should reduce the dose.

When growing your hemp outside or in good and rich soil, you need not add any additional nutrients. Make sure the pot is large enough for the roots to grow freely.

Vegetative growing phase:

In this phase, the plant needs high nitrogen (N) and potassium (K) levels and a medium intake of phosphorus (P). A good rule of thumb would be to use that the amount of phosphorus (P) should be around half of the nitrogen (N). Potassium (K) levels can vary from one-third to half of the nitrogen. 

Flowering phase:

When your hemp or cannabis plant arrives in the flowering phase, the nitrogen (N) level should be drastically lowered, at the same time the phosphorus (P) level should be increased. The potassium (K) level can ben maintained at the same level. 

Hemp Seeds

There are a lot of hemp seeds available on the market with different characteristics, so the seed you need really depends on what you want to accomplish. 

It’s recommended to choose a feminized seed because only the female plant gives crops. The problem with these hemp seeds is that they are more expensive than general hemp seeds.  

The other question you should ask yourself is what the perfect CBD: THC ration should be. Depending on your target market you should choose a string that contains the right CBD: THC ratio.

Do you grow the plant indoors or outdoors? The seed right for you will depend on the conditions of the environment. Is the environment dry or moist? Hot or cold? These environmental conditions will affect the quality of the crop.

Hemp Clones

Instead of seeds, you could also choose for clones. The benefits of going for a clone is that you already know the gender, reliability, and is also much faster.

Another benefit of using a hemp or cannabis clone is that it requires less care. Seedlings need much more care and observation.

Conclusion

It’s possible to grow your own hemp but before you do make sure that the law in your state/country allows you to grow hemp.

It could even be a nice hobby to have. In the next article, I will dive deeper into how to make your own products from the hemp or cannabis plant.
