Every cultivator of cannabis eventually learns about the most helpful tools that can make growing weed easy, and super soil is one of the easiest to use with the most effective results. Since super soil is not a highly sensationalized growing tool, few consumers know much about it, but that’s ok because we’re here to change that with this handy guide that covers everything you need to know about super soil including what it is, how to use it, how to make it, and more.

What is super soil?

Cannabis super soil is an organic growing medium that is full of all-natural ingredients that will help a pot plant to thrive. All true cannabis super soils are organic and start with plant-based ingredients, including compost, peat moss, and an aerating agent.

How to grow marijuana using super soil

Super soil is a natural combination of ingredients that results in a mixture that looks and acts like your average garden earth, which is part of what makes it an excellent tool for beginners who are just learning how to grow marijuana. Using it doesn’t require any special tools or pots, so you can just fill up any old pot with it and get started with a clone or germinated seed.

Also, ensure that the super soil stays moist, as that is a necessary part of the equation for the nutrients and micronutrients to form and, eventually, be delivered directly to your marijuana plant through the roots with every future watering.

Super soil is just like any other potting earth and requires little to no special treatment to water your marijuana plants. Just slowly pour small amounts of distilled water to the soil until you notice either small puddles at the base of the plant or excess water streaming out of the bottom of the pot.

Is Happy Frog a super soil?

Many first-time growers hear incredible things about Happy Frog, and so they rush to order soil directly from the company in hopes of it acting as a perfect super soil. Unfortunately, Happy Frog soil is no more than a base soil. It can be combined with other ingredients to create a super soil, but it is a pre-made option fresh from the bag.

Do you need to flush super soil?

One of the most wonderful benefits of using super soil to grow cannabis is that it negates the need for additional fertilizers, so it rarely needs to be flushed unless you choose to use additional products. Flushing cannabis is a process that is performed to cleanse the plant of any residual chemicals or fertilizers that might impact taste and the consumer’s health, but it’s a step that is not necessary if you grow your marijuana using only pure super soil.

What is the best super soil?

There are several companies that claim to provide the very best super soil products on the market, but since this is one side of the market that is, for the most part, unregulated, there is no way to confirm the consistency or quality of these pre-made options. The best super soil will always be one that is made from scratch by yourself, that way you will know everything that goes in is safe so that upon consuming the end product, there’s no need to worry about potential health hazards.


Here we will explain how to make not only the base of a good soil mix for cannabis but also how to produce beneficial fungi and bacteria that will continue to slowly and naturally fertilize your plant throughout its entire lifespan

While technically this cannabis super soil can be used outdoors as well, for it to be the most beneficial as a good soil mix for cannabis plants, cannabis super soil is used mainly when growing indoors. Otherwise, it will take a lot more of it to produce the same results in an outdoor garden. This is an entirely organic super soil recipe and only requires a few essential ingredients and a little bit of time to get started.

Below we will explain how to make not only the base of a good soil mix for cannabis but also how to produce beneficial fungi and bacteria that will continue to slowly and naturally fertilize your plant throughout its entire lifespan.

Base ingredients

  • Compost
  • Perlite
  • Peat moss

Ingredients for fungi production

  • ¼ cup of kelp meal
  • ¼ cup of humic acid
  • ¼ cup of Mycorrhizal
  • Water

Ingredients to establish good bacteria

  • Worm castings aka vermicompost
  • Guano (produced by bats)


  1. Mix even parts of all three ingredients on whatever scale is required to produce enough cannabis super soil for your needs. Once done, you will have a base of healthy soil.

  2. Microbiology plays a considerable role in establishing a healthy source of nutrients for a marijuana plant to feast on through the various stages of growth. Fungi specifically will develop a relationship with the cannabis plants rooting system, giving it an extra boost since you are trying to produce as much food as possible for your plants to feast on. To do this, mix a solution of ¼ cups of kelp meal, ¼ cup of humic acid, ¼ cup of Mycorrhizal inoculant, and 5 gallons of water. This can be used to prepare the cannabis super soil before planting and for regular watering up until the flowering stage.

  3. Now you need to focus on raising the good bacteria present in your organic super soil. Good bacteria will aid a marijuana plant’s ability to break down sugars and convert them into nutrients. They also play a role in the cannabis plant’s initial establishment of its immune system, making them more resistant to some of the most common cannabis pests. To increase the positive bacteria population in your soil, add up to 20% worm castings and up to 5% of bat guano. Any more than that has the potential to burn the plant.

  4. Add extra strength to your cannabis super soil using micro or macronutrients. This can be done by using any one or more of the following soil amendments:

  • Bloodmeal - produces high levels of nitrogen
  • Bonemeal - adds a healthy dose of calcium and phosphorus
  • Epsom Salts - are full of magnesium
  • Rock Phosphate - is phosphorus
  • Crustacean Meal - is packed full of essential nutrients like nitrogen, calcium, phosphorus, and magnesium
  • Dolomite Lime - can help to maintain a consistent PH balance and adds a dose of magnesium to your organic super soil
  • Azomite - is full of micronutrients that are long-lasting
  • BioChar or Wood Ash - will add potassium to the soil mix
