What is the Best Way to Start Weed Seeds?

Now that we have talked about some of the best products that are available on the market, let us now discuss some of the basics of growing weed seedling. Let us start with the best way to grow it. Here are some of the things that you need to know:

  1. The first thing that you need to do is to choose the best feminized seeds to grow. Decide on where you intend to grow the cannabis. Once you know, it will be easier for you to choose from the best marijuana seeds to grow outdoors and indoors. Choose a healthy seed from a trusted supplier, which is one of the best ways to prevent frustration.
  2. Start sprouting the seeds. The towel method can be a promising choice when it comes to allowing the seed to germinate. You can also sow it directly on your medium of choice. This will eliminate the need for transplanting, which will minimize the stress that the plant can experience.
  3. Wait for the seedling to grow and make sure that you take care of it throughout the process. Choose an ideal location for its growth and control the external environment in such a way that it will be favorable for the growth of the cannabis. This is one thing that will be easier to do if the plant is grown indoors.

What is the Best Medium for Marijuana?

Aside from knowing the best way to sprout pot seeds, you also have to be familiar with the mediums that are available, which include those that will be briefly mentioned below.


This is one of the most popular mediums amongst cannabis growers. While there are many soils that are available on the market, this does not mean that you can choose just any medium. Aeration and permeability are two of the most important considerations. The right soil is important to boost the development of roots, as well as in the prevention of pests and diseases.
The soil needs to have nutrients that will help the seedling to establish its roots. Sterilized and loose soil will be the best choice for growing cannabis. It will also be good to have at least 20% mixes in the soil, such as perlite. This is going to improve the drainage capabilities of the soil, improving the amount of oxygen that is present to speed up growth.

Coco Coir

If you want to have a soil-less medium, this is the one that you have to use. This is an organic medium that comes from frayed and ground coconut husks. It has a good pH balance and will be instrumental in improving the supply of oxygen to the roots of the cannabis. It has a great aeration property, which is one thing that makes it better compared to soil.
However, one of the problems with coco coir is that it tends to become dry quickly. A good solution to this is to ensure a sufficient supply of water.


This has been one of the most innovative gardening methods, even when it comes to marijuana cultivation. While there are many types of hydroponic systems, one of the most popular amongst cannabis growers is known as Deep Water Culture or DWC. This is one of the best ways for your seedlings to become large quickly.

What is the Best NPK Ratio for Weed Nutrients?

As you search for the best nutrients for growing marijuana, one of the most important considerations would be the blend of the NPK nutrients that should be present in the product that will be used. This will depend on the specific stage of the growth of the plant. Nitrogen, phosphorus, and potassium are three of the most important nutrients the weed will need to survive.
During the vegetative stage, you need to use a fertilizer that has high nitrogen, medium phosphorus, and high potassium. On the other hand, during the flowering stage, you should pick a fertilizer that is low in nitrogen, medium to high in phosphorus, and high in potassium.
If the soil already has a high nutrient content, you can skip the use of fertilizer during the first four weeks of planting. You should avoid overfertilizing as this can inhibit the growth of the plant, which is sure to be a frustrating situation.
It is important to note, however, that aside from the nutrients, the pH level of the soil will also have a huge impact in the growth of cannabis, which is why it deserves your attention as well. The pH level should depend on the medium that you are using. For soil, it should be 6.0 to 7.0. Meanwhile, for coco coir, keep it at 5.5 to 6.5. The same level will also be best for hydroponics.

Which is Better for the Best Nutrients for Weed Plants: Organic or Chemical?

This is another question that you need to answer before you start searching the market for the best products to use. Chemicals always have a bad reputation. However, in reality, they can also offer a number of advantages.
Organic nutrients as great when you are planting in soil because of the natural components. It can help in improving the smell and the taste of the buds, making it influential of the quality of the harvest.
Meanwhile, when looking for the best nutrients for hydroponic weed, chemical is the way to go. They will help in preventing the growth of anything in the water reservoir that could affect the health of the roots. Chemicals are also known for enhancing the potency and speeding up the growth of the plant.

Wrap Up

With the best nutrients for weed seedlings, including those that have been mentioned in this post, you can have an assurance of a healthy plant up to the harvest stage. Take note, however, that not all fertilizers are the same. Start by considering the medium that you are using, and from here, you can begin your search for the best fertilizers!

  1. hi how you doing I’m a begginer and I just started using a product that’s 6-12-6 called Medina , my plants are about two and half weeks old I added half an ounce of the nutrient into a 1 gallon tank and added them to my plant but they have turned a little yellow, im wondering if its affecting them or maybe im over watering them. the leaves are standing up and not drooping or anything im afraid the nutrients are also burning them.

  2. Lmfaoo.yea u don’t use chemicals first few weeks . Lightly , very lightly mix small amount of nutrients into you soil . Wait till your plants at least 6” or so with 2-3 node sets before adding nutrients directly. Restart seedlings . Don’t rush growing or be cheap with your grow foundation . It’s all about a thriving , well habituated & well kept garden . STOP RUSHING AND DO YOUR READING AND RESEARCH
