This cooking time lets the ingredients break down. It also helps the soil create good bacteria. This bacteria works with the plant’s roots.

Creating your own super soil is good for your garden. It makes caring for your garden easier. Your plants will also be healthier.

Organic Soil Recipe

This system was constructed for those that want to have a birds-eye view of the entire process from start to finish. Many people want to grow naturally and just don’t trust that it will work. Some are doing it now but they are missing some key element and it’s not coming out quite right. Once you get the full picture and understand how flexible this super soil system is you will be able to create your own system that works in your garden.

The ultimate goal is to use nothing but homemade compost that has been created with all of the nutrients built-in. If you can get to the point where your soil is so alive and healthy that all you have to do is plant a seed and add water, then you have arrived. Having the best soil doesn’t have to take forever and in the meantime, there are many Compost teas, Botanical Teas, and fertilizer inputs that you can add to Build-a-soil for long-term production.

The modern way is to use chemistry to make NPK and several micro-nutrients available to the plants through the use of plant ready water-soluble nutrients. The PH of the nutrient supply will heavily affect the outcome of the plant. This is the “Feeding the plant” Paradigm.

The organic way is to build a compost based on the plants that are high in nutrient content and to utilize organic amendments that work with the plant and the soil. Combine premium compost materials with diverse minerals and utilize biology along with science. We are constantly testing soils. We want diversity and we want it all in the soil. The nutrients aren’t immediately available in the organic system, we will rely on the biology of the soil to naturally produce nutrients for our plants based on it’s growing needs.

Rules of Thumb

1. Don’t try to grow a plant, instead build a soil that does that for you: Use Premium inputs and get premium results. Your goal is to build the best soil possible and keep it as a pet. Keep it moist and alive as best as you can input more than you take out and the soil will last forever as it continues to evolve and become more blessed with life.
2. Learn to make your own compost and your own Earthworm Castings: You would be surprised how small of a space you can make quality compost in. Search our website for “indoor compost” and you will see what I mean. But if you really can’t do the whole compost or worm bin thing, then I suggest you learn to find a really good source for local compost that is affordable. If you can’t find compost local then use our pure worm castings. The shipping keeps the price a little high, but my goal is to make this as affordable as possible for everyone to benefit from.
3. Use premium quality compost or earthworm castings, preferably homemade. Yes, I said this twice. It’s that important.
4. Don’t be tempted to go back to the bottled nutrients: Even if they say organic because nothing will be as good as your own soil. The big bottled nutrient companies buy ingredients in bulk and often use soy and cotton that are GMO and full of pesticides. Get this right and your garden will be more productive and more nutritious than ever before. Don’t worry about growing plants, focus on building soil!
5. Avoid ingredients that say they are organic but really aren’t good for the environment. The Organic Label is slowly selling out in the marketplace depending on who is doing the certification. Don’t worry if it’s not organic as long as you know where it came from and that it is good stuff. Think about each ingredient in the products you purchase. Just because the nutrients at the grow shop have cool labels and high prices do not mean that they will grow better plants.
6. No matter what else you do, make sure you MULCH. If you skip Mulching you are missing the boat.

*Don’t worry about being exact, just get a good mix together and lightly moisten it all and add your soil amendments and then let sit for 2-4 weeks before planting into it. You can mix it up on a tarp and then wrap it up in the tarp until it’s ready or you can scoop it all into a trashcan or just simply into a huge pile in the garden. with all these premium ingredients it would best to keep this soil mixed up and covered. This will allow it to heat up and break down any of the ingredients that require more composting before you plant into it.

Tips For Building Your Own Super Soil

Organic gardening doesn’t worry much about pH. This is different from using synthetic nutrients and other mediums.

When you garden organically, most pH problems are in the soil. Start with a growing medium full of humates (humus). Humates help balance most additives you add later.

Humates come from compost, worm castings, and bottled humus. If your medium is peat-based, dolomite lime can fix its acidity. Dolomite also adds magnesium and calcium.

A medium of coir has a pH close to neutral (7.0). But, humates are still key for taking in nutrients outside this range.

An active medium with humates can handle nutrients like Pure Blend Pro and Earth Juice. These nutrients can be far from the ideal pH. Humus lets the roots absorb them, even at extreme pH levels.

So, forget about pH meters and enjoy organic gardening’s ease and safety.

Chlorine tap water is a warning for organic gardeners…

Tap water with chlorine kills good bacteria in your soil. This harms the living ecosystem of your organic soil.

To fix your water, fill a 5-gallon bucket. Add an air stone and air pump. Let it aerate for 24 hours before using it.

‘Cooking’ super soil means creating a warm, contained space. Use a large tub or cover your mix with a tarp. This starts the breakdown process and creates a rich environment for your roots.

Paramount Seed Farms suggests ‘cooking’ for at least 10 days. Some growers prefer up to 6 weeks. Mix and rotate your soil every 10 days to keep microbes evenly distributed.

Starting your own soil can seem hard at first. But after your first batch, it’s easier. Just make sure you have enough.

You can reuse your super soil and ‘recondition’ it each season. Improve old soils with organic compost tea recipes. Don’t forget to use LABs Foliar Spray regularly. Happy gardening!
