Growing cannabis at home can be a fun project and a nice way to have your own cannabis plants on hand. You may want to grow cannabis indoors due to inclement weather in your area or due to a lack of green space in your yard. Start by germinating the seeds. Then, plant the seeds in soil or in a starter cube. Once the seeds have been planted, care for them properly so they grow and thrive.

To plant cannabis seeds indoors, first soak the seeds in lukewarm tap water for 12 hours. Discard any seeds that float to the top. Then, place the seeds on a damp paper towel on a plate with 1 inch (2.5 cm) of space between each seed. Cover the seeds with another damp paper towel. Keep the seeds in a spot that remains between 70-80°F (21-27°C), and spray the paper towels with water whenever they start to dry out. The seeds will sprout in 2-3 days. When they do, fill pots or a growing tray 3/4 of the way with loose potting soil that has a pH between 5.8 and 6.3. Press the soil down lightly, leaving some air in it. Then, use a pencil to poke 1 inch (2.5 cm) holes in the soil. Place the sprouted seeds vertically in the holes and fill the holes with potting soil. Water the soil thoroughly and place the pots or tray in a spot that’s always 75°F (24°C) or warmer. Set up a grow light over the seeds and leave it on at all times. Water the seeds every day so the soil doesn’t dry out. The seedlings will emerge in 2-4 weeks. To learn how to use cool white grow lights to help your cannabis seeds grow, keep reading!

Although that list looks vague and complicated at the same time, the requirements you want to meet are actually pretty simple; let me break it down!
If you get the soil part right, you have almost everything you need to get to harvest! With the correct texture, drainage and water retention, you’ve got a perfect base. Add good soil cannabis nutrients, especially in the budding phase, and you should get to harvest with great results!
Texture, Drainage & Water Retention.
In order for a cannabis plant to grow and thrive, it needs a good mix of both water and oxygen at the roots at all times! Too much water and the plant roots can’t get enough oxygen (lack of oxygen at the roots is why plants get droopy from overwatering) but on the flip side if there’s not enough water retention the roots can be injured from drying out too quickly!
Here’s organic “super” soil up close.
Super Soil has a colony of micro-organisms living in the soil which form a symbiotic relationship with your plant roots. They deliver nutrients to your plant, and in return they eat the sugars that get secreted by your roots!
This plant is growing in Fox Farm Ocean Forest Soil.
I think most growers agree a good cannabis soil should look dark and rich, with a loose texture that drains well and can hold water without getting muddy (you want wet soil, not dirt-batter!). But beyond that, what do you look for?
Some growers choose an amended and composted “hot” soil that slowly releases nutrients over time. With this type of soil, you typically just add water or natural supplements like worm tea from seed to harvest. Other growers prefer a lighter potting mix so they have more control, and give nutrients in the water once the plant roots have used up the nutrients in the soil. But which brands can you trust?
Example of “Good” Cannabis Soil Ingredients.
It’s easy to get caught up thinking about what nutrients and amendments are in the soil, and those are important, but perhaps the most important aspect of any soil is actually its texture, ability to drain, and overall water “holding” ability.
However, when growing with Super Soil, it’s a good idea to avoid watering too much at a time, as extra runoff waterwill drain away some of the nutrinets. Try to give just enough water to saturate the soil with very little extra coming out the bottom. Since you won’t be adding more nutrients through the grow, you want to conserve what’s in the soil!

Signs of Good Cannabis Soil.
Espona Organic Potting Mix is found in many stores in the US, and works for growing cannabis!
This is what kind of soil to get if you don’t have any “good” soil available, but want something that is known to work for growing cannabis.
The “micro-herd” in the soil delivers nutrients directly to your plants. As long as you’re using decent water, you usually don’t need to worry about pH or other things that can disrupt nutrient absorption in regular soil.

Fox Farm has been around for over 30 years and makes some of the most common types of “cannabis soil” (at least in the US). They have several great soil mixes, including “Happy Frog” which is a great choice for seedlings and clones.
Of these types, loam is by far the best soil mix for growing marijuana plants and many other types of crops. Loam is a mixture of clay, sand, and silt, bringing forth the best qualities of these disparate types of soil while minimizing their worst attributes.
Growing cannabis outdoors offers many benefits. Firstly, it can be very affordable. You do not need to provide a structure like a greenhouse or high tunnel. In addition, artificial light is not necessary if you place it in the right spot in your yard, because your plants can benefit from the sun’s abundant and free energy.
Silt soils have lots of minerals and retain moisture well. Like clay, however, this type of soil can become compacted and hard in certain conditions. It can also form a crust, making it difficult for moisture and nutrients to reach plants’ roots.
Test kits are available to measure your soil’s acidity, or you can take a sample to your friendly local extension agent. If your dirt does not have the proper acidity, soil amendments are available to lower or raise the pH level in your soil. Your local nursery, garden store or extension agent can make some suggestions.
Loam is ideal for containers as well as for outdoor growing. Unfortunately, it is usually the most expensive soil to buy. But if you are interested in growing the best plants possible, it can pay big dividends in the long run. You can also build up your own loam soil by adding organic matter to it. If you have a compost bin, you can use the compost to improve your soil. This will be a time-consuming and ongoing process but with grit and persistence will pay off in the long run.

You will want to provide the proper amount of light and water to your plants, of course. A drip irrigation system can cut your water bills while improving the health of your plants. Kits are available that give you everything you need to get started. If you prefer, you can start from scratch and obtain separate components to put them all together.
Just like humans, plants need the right nutrients. The most important ones for your cannabis plants are nitrogen (N), potassium (K) and phosphate (P). These make up the ratios you will typically see on fertilizer labels.
In addition, you do not necessarily have to provide costly soil for your plants outside. But for the best results, you want good marijuana soil that will help your plants grow healthy and happy. DripWorks is here to offer you a few simple tips for finding and creating the best soil for growing marijuana outdoors.
Four basic soil types exist: sand, clay, silt, and loam. Each has its pros and cons for gardening.
Sand is easily permeable for root growth, for instance, but it does not hold on to water or fertilizer well.
The optimal ratio for loam is 20% clay, 40% silt and 40% sand. Most folks think a pH of 6.0 is best for cannabis, with a range of 5.8 to 6.3 being acceptable. With a pH close to neutral, loam is typically in that zone or close to it.
Clay is just the opposite. When it’s hot and dry, clay can become hard as a rock, making it difficult for roots to penetrate. Clay drains poorly and is hard to cultivate. On the plus side, it is rich in minerals and natural nutrients.
The right balance is essential for healthy growth. Many pre-mixed marijuana fertilizers are available, making your job easier. But if you prefer, you can also formulate your own.
