After reading this review of soil mixes, I am sure you get all the necessary know-how to bloom your indoor weed plants. Choosing the perfect soil might tangle you in confusion, but following this guide will clear any doubt you might have.
This review is going to be very helpful for indoor cultivators. Growing cannabis indoor is such a thing that it requires perfect knowledge about every single thing. If seed quality, soil quality, and growing environment are not ideal, you cannot receive high yields!
It is essential to choose soil that lets water and air stream flawlessly. Having said that, this soil carries coconut coir to allow water to flow adequately.
Advantages: Good drainage, naturally fertile, water retention, comfortable to work with, supports microorganisms, nutrient retention, and a high percentage of oxygen. Disadvantages: Can be costly than others.
Vermiculite enhances nutrient and water retention capacity. It can also help improve the airflow in soil. Interestingly, vermiculite outperforms perlite in water retention ability! Consequently, you will get healthier and excellent quality buds quickly.
Furthermore, it has brilliant sustenance for initial root growth. You can rest assured that you will get abundant yield by using this progressively nutritious soil pack.
If you are a beginner grower, you must purchase your soil from a garden store. Did you know that the vast majority of expert growers also buy their soil? A handy tip when talking with a store employee is to ask about the right kind of soil for tomatoes. It is an excellent option if you feel uncomfortable disclosing your desire to grow weed!
When buying soil for weed, make sure you understand the basics of good cannabis soil. If you want your plants to offer lots of cannabinoids and trichomes, you have to pay attention to several variables. including:
Ultimately, you can choose between soil or a hydroponic system if you wish to grow weed at home. A hydroponic system is potentially extremely effective, but it is also expensive. Generally speaking, those cultivating their cannabis for the first time should choose soil. The roots of your plants will extend deep into the earth as they look for nutrients and water.
That’s why indoor systems, which have a lack of space, need to create smaller root systems for marijuana. Regardless of the root system you choose, make sure the temperature in the growing area stays around 68 degrees Fahrenheit.
In case you weren’t aware, pH means ‘potential of hydrogen.’ It is a chemical scale that determines a substance’s alkalinity or acidity. The range goes from 0-14. A pH of 7.0 is neutral (pure water is 7.0, for example). Everything from 0-6.9 is acidic, while everything from 7.1 to 14 is alkaline.
Best Soil for Growing Weed Outdoors.
On the plus side, sandy soil is easy to prepare for cultivation, offers good drainage, and contains high oxygen levels. It is one of the best options for growing weed indoors.
This is a prevalent marijuana potting soil and has an almost neutral pH. It offers excellent drainage and water retention, contains high oxygen levels, and is naturally fertile. However, it is by far the most expensive option.
When growing weed outdoors, make sure you use soil that feels fluffy in your hands. It needs to possess a reasonable amount of nutrients, and good drainage is essential. Compost and store-bought fertilizer can form a fertile and productive base. Crucial nutrients include Nitrogen, Potassium, and Phosphorus.
When you water the plant, it moves essential nutrients and minerals to the roots. Then, they travel to the rest of the plant. Water cools overheated plants down and is a critical ingredient for photosynthesis. The best advice we can give is to water the soil until it is moist, but not wet to the touch. Overwatering aids the growth of harmful fungi, which can result in root disease, so exercise caution!
The trouble with organic matter is that it gets depleted rapidly. This means you have to amend it on a season by season basis.
This enhances water retention and causes your soil to become ‘lighter.’ It works particularly well with Perlite.
As long as you choose correctly, your cannabis soil should already have a vast array of nutrients because it consists of organic material. One mistake is to try and add organic material such as animal manure and rotting vegetables directly to the plants as fertilizers. You must break down the content first if you want your marijuana plants’ roots to absorb the nutrients.
This is made from coconut husks and manages to improve water retention without causing the soil to become heavy. When you use coco coir, the roots of your plant should develop quicker, and you’re less likely to overwater. You can grow your marijuana in pure coco coir. However, a maximum of 30% is best for a productive soil amendment.
Before we continue with the best soil brands for growing cannabis, let’s look at general guidelines for indoor and outdoor soil.
Once it reaches a height of 25cm, transplant the plant(s) to a container that is at least double the size of the first one. Once your plant hits the lofty heights of 80cm, move it to at least a 12-liter container. Once your plant hits a meter in height, you’ll need an even bigger box. This process continues until harvest.
If you try to use this kind of soil, expect to have difficulty in getting the plant’s roots to penetrate the surface. Clay soil has a high pH. While it stabilizes plants, the soil is heavy and requires a lot of effort overall.
This is a great option if you want to nurture your crop from seedling through to harvesting. This Espoma soil contains excellent nutrition for early-stage growth. You will need to begin with small pots, before transferring your growing plants later. It contains peat moss, perlite, and peat humus – not to mention a hose of nutrients that aid strong root growth.
Sandy soil is known for its large granular size and has a low pH. The issue with this type of soil is that it dries quickly and often experiences difficulties in moisture absorption. The nutrients also get washed away, and nitrogen, in particular, is lost rapidly from sandy soil.
The texture, drainage ability, and water holding ability are arguably the most critical aspects of marijuana soil. Your plant will not produce a good yield if it doesn’t have the right mixture of water and oxygen in the roots 24/7. If there is too much water, the roots won’t get enough oxygen. If there isn’t enough water, the roots can dry out quickly and become damaged.
It is unlikely that your cannabis soil will have the ideal drainage, texture, and water retaining abilities. Fortunately, there are a host of amendments available to alter the drainage, texture, and water-retaining capacity of your soil. Here are four of the most popular:
This soil type consists of minerals such as quartz and fine organic particles. Although they hold moisture, silt soils have decent drainage and are one of the easiest to work with when wet. Also, silt soils are among the most fertile, which gives you a chance of a decent-sized harvest. With frequent irrigation, you can extend the length of the growing season. Silt soil is one of the best soil types for seedlings.
The amount of work you must do depends on the balance of your existing soil. For instance, if it has high amounts of clay or sand, you’ll have to add large amounts of organic matter several times a year. You can add a two-inch layer of organic matter onto the surface of the garden. Then, you should work it into the first couple of inches of soil.
Choosing the Right Cannabis Soil Container Size.
Natural soil comes in four varieties: sandy, silt, loam, and clay. You are in for a nasty surprise if you think that soil is just one ‘type.’
Many soils will have a combination of at least two of the four types. Therefore, you can have sandy/silty, loamy/clay, silty/clay, and so on. If that isn’t confusing enough, there are different ratios of every soil type. It is an important consideration, however, because each one has its pros and cons.
This is probably the most commonly purchased amendment and is ideal for practically any soil mix. It consists of airy ‘rocks’ known for their white hue. Perlite looks a bit like popcorn and improves drainage while adding oxygen. Use 10-20% to improve water retention. You can go as high as 40%, but you risk leaching nutrients faster. If you use Perlite and Vermiculite, don’t go above 50% for the two combined.
Battery acid and hydrochloric acid have a pH of 0, while liquid drain clearing fluid has a pH of 14. Ideally, your cannabis soil is slightly acidic. Most experts believe that the ideal pH is 6.0. However, you are on solid ground if your soil’s pH is between 5.8 and 6.3. Your crop will survive outside of this range, but the yields are likely much smaller. If you stray too far from the 5.8-6.3 range, the plants will die.
The apparent simplicity of picking soil often fools newcomers, and they frequently make mistakes that cost them their harvest. The truth is, you have to make a lot of considerations. For example, the soil you use for indoor growing is not the same one you’ll need for an outdoor grow. Then there is the small matter of things like pH, drainage, and a host of other criteria.
Whether you want to call it dirt or a growth medium, soil is a crucial component for growing marijuana. Choosing the best soil for your weed is arguably the most critical decision you’ll make when growing cannabis at home. Getting it right is likely the difference between a bountiful harvest and utter failure.
It is, however, the best soil for cannabis, which means it is worth the time and effort that you have to put in. No matter what type of soil you have, creating loam involves adding organic matter to it each year. The decomposing plant material creates the excellent drainage conditions your weed needs.
Loam soil is a combination of sand, silt, and clay, typically in a 40/40/20 ratio. It has at least 20% organic compounds and can vary from being easy to work with to incredibly complex. To identify a loam soil, squeeze it. It should form a loose ball that quickly threatens to break apart.
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?
Their Ocean Forest soil mix is “hotter” soil (higher levels of nutrients) that contains ingredients that cannabis plants love, including earthworm castings, bat guano, fish meal and crab meal. The nutrients contained in the soil will provide everything your plant needs for several weeks. Although it might give young seedlings just a touch of nutrient burn at first, they can be started in Ocean Forest soil and will soon be able to use the nutrients and start growing quickly. Some growers might put a little big of Happy Frog on top of a container of Ocean Forest, just to make it a little more gentle for seedlings the first week or two.
When cannabis growers talk about “super” soil, they’re usually referring to soil that has been amended with slow-releasing organic nutrient sources, and then composted for several months (learn more about super soil).
Important Cannabis Soil Considerations.
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.
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!
What gets the best results for growing cannabis is a soil with a light texture that is good at retaining water…but not too much!
Good Cannabis Soil Rich and light composted soil. Since this soil doesn’t have a lot of perlite, it’s a good choice for a grower who doesn’t want to add a lot of extra nutrients or supplements in the water.
The following video shows the soil texture you want (this is Coco Loco, an excellent soil for growing cannabis)
Fox Farm Ocean Forest Soil.
Espona Organic Potting Mix is found in many stores in the US, and works for growing cannabis!
Good Cannabis Soil This soil has quite a bit of perlite, which is a good choice if you plan to feed heavily with nutrients and supplements since the extra perlite prevents nutrient buildup in the soil.
Usually an organic potting mix does not have enough nutrients to last your plants for more than a few weeks, so it’s a good idea to always supplement with cannabis-friendly nutrients, especially in the flowering stage when your plant is making buds and needs lots of extra Phosphorus and Potassium.
When it comes to growing cannabis in soil, unless you’re using a brand that is known for making soil that is specifically cannabis-friendly, there are a few things that you need to consider before starting a grow.
Kind “Super” Soil (Living Soil)
Try to get soil that looks like this!
Nugbuckets is a famous organic soil grower! Check out his plants!
If you are willing to keep transplanting to bigger pots as your plant uses up the nutrients in the soil, you don’t need to supplement with extra nutrients. However, even if you grow in the same pot from seed to harvest, Fox Farm offers a complete nutrient system that is also formulated for plants like cannabis and goes perfectly with their soil to make sure your plant is getting the right levels of nutrients throughout its life.
Generally, anything labeled as an “organic potting mix” will work. This type of mix hasn’t been amended with chemical slow-release nutrients, which is one of the main things you want to avoid with soil for cannabis. I know it sounds like heresy, but even the Miracle-Gro version of “organic potting mix” will work okay, because unlike their original potting mix it doesn’t contain chemical nutrients (though it still has poor drainage and moisture retention – almost any other type of organic potting mix is better!).
Good Cannabis Soil Another light, rich soil mix with great drainage. Although there is a wood chip in this picture, for the most part the mix is completely composted and broken down. It’s normal to see some wood pieces in composted soil, but you don’t want to have to wait for a lot of wood to break down while your plants are growing – you want all that rich nutrient goodness to be readily available to your plant roots 🙂
