Best Soil for Cannabis

Best Soil for Cannabis


Cannabis, like all other plants, thrives from an ample supply of water, oxygen, and nutrients. These three base components are responsible for your crops overall health, growth rate, and final yield.

Of these three factors, soil composition is one of the most easily modified to suit the needs of cannabis crops. Due to this, cannabis-specific soil mixtures are a booming industry.

Although the nutrients themselves arent altered, they are added in specific amounts that promote healthy growth for cannabis plants. Without these pre-made soil mixes, cultivators would be left to compose their own.

The main question is: whats the best soil for cannabis?

Pre-made cannabis potting mixes allow beginners and professionals alike to jump into the fast lane for growing marijuana plants. Youll find everything your plants need in these soil mixes, such as beneficial bacteria, fungi, macronutrients, micronutrients, vitamins, and more.

Furthermore, cannabis-specific soil mixes provide a more natural form of growth, as compared to the hyper-accelerated growth of hydroponics or aeroponics.

Weve sifted through countless soil brands to find you the best soil for cannabis. Whether youre searching for an organic solution or an all-in-one soil mix weve got your plants covered so they can grow on cruise control.

Buying soil for your cannabis plants might not seem important, but its one of the biggest deciding factors when it comes to plant health and overall yield.

Cannabis plants take anywhere from 4-6 months from seed to harvest. Clones may take upwards of 3 months to complete their life cycle. Not only is this a significant investment in time, but also the energy needed to fuel their growth.

This is why weve compiled this buyers guide to help you find the best soil for cannabis plants.

Before you give your hard-earned money away, how many cannabis plants will you grow? This is the first question you must ask yourself because itll paint a clear picture of how much soil youll need.

If youre growing a single plant or 6-plants in small containers, you wont require a bale of soil to fit your needs. Instead, you can get away with purchasing a single bag to keep your costs to a minimum.

However, if youre growing multiple plants in large containers, then youll need to purchase multiple bags or a large bale-size bag of soil.

Whether youre growing a warehouse full of cannabis plants or a single plant in your closet, knowing how much soil you need is the very first step you must take.

This is the next important factor that you must consider. Do you want a soil mix thats filled with all the necessary nutrition for your plants, or are you seeking a mild soil mix that can be amended with additional supplements?

If you choose a stand-alone potting soil product, then it might not be suitable for seedlings due to the overall strength. If you decide to go with a milder soil mix, then youll need to purchase additional nutrients.

Some growers find more freedom in purchasing soil mixes that contain fewer nutrients so they can fine-tune their overall overall nutrient content.

However, this method is only recommended for cultivators with experience. If youre a beginner, fine-tuning your soil mix may prove to do more harm than good.

Beginners will benefit from utilizing a stand-alone soil mix for cannabis because it contains everything your crop needs to thrive from seed to harvest.

Although these products are not packed to the brim with nutrients, they will allow you to grow vigorous and high-yielding crops without the worry of nutrient burn.

This is another essential question you need to ask yourself. Organic soil mixes contain ingredients that are from organic sources, which is scientifically proven to be better for the environment and your overall well-being.

Inorganic potting mixes tend to be cheaper in cost, but the price difference isnt as large as in the past. Ultimately, this is a very personal question that only you can answer.

Next, youll need to understand if youre looking for a soil mix that contains beneficial microbes or not.

You may question this idea at first, but fungi (mycorrhizae) and bacteria play an integral role in breaking down nutrients for your prized cannabis plants.

In other words, beneficial microbes facilitate enhanced nutrient absorption, promote root growth, and provides a protective barrier against harmful bacteria and fungi.

Although youll likely see an increased price tag on soil mixes that contain beneficial microbes, its well worth it when you consider the effort it takes to grow high-quality cannabis flowers.

This is the main question that beginners ask. In fact, growing cannabis in soil is one of the easiest methods because its by far the most natural.

The vast majority of soil brands offer plug-and-play soil mixes. This means that you dont need to do anything except water them.

In these cases, youll need to look for soil brands that are already within the optimal pH range. By finding a pH balanced soil mix, you wont need to worry about complicating matters with a pH pen.

Just like animals, your cannabis plants rely on oxygen to thrive. Alongside water and nutrients, air is a necessity when growing cannabis plants in soil.

Perlite is a primary material that cannabis growers use to increase the amount of air inside a soil mix. Not all soil brands contain perlite, so its essential to understand if your soil mix is too heavy.

Air pockets within your soil mix not only provide oxygen for the roots, but they also allow the root system to expand rapidly.

Furthermore, consistent air pockets within the potting mix enhance drainage, which will reduce the possibility of fungus and bacterial rot.

Growing cannabis in soil is incredibly straightforward, especially when its already pH adjusted. Here are a few tips on getting your soil ready for your marijuana plants.

The first thing you need to do is fill your container 3/4 full with potting soil. Gently place your plant, and carefully add additional soil to cover the roots.

The cardinal rule is never compact the soil. Cannabis roots not only thrive from the nutrients within the soil mix, but also from the air pockets.

These tiny pores keep roots from rotting, so its essential that you refrain from pressing down on your soil mix.

If your soil mix is already pH adjusted, then you simply add water. Always allow your plant to satisfy its thirst before adding more water to avoid overwatering symptoms.

Now that you understand the importance of potting soil mixes for cannabis, lets take a look at the best soil mix for cannabis.

Overall, Fox Farms Happy Frog potting soil is the best nutrient mix for cannabis plants. Whether youre a commercial cultivator or small-scale home grower, Happy Frog is a versatile potting mix for any type of cannabis strain.
