Royal Gold: Organic Potting Soil

Royal Gold is proud to have been the first coco pith based soil company in the United States. Made from the husk of the Coconut, Coconut coir naturally contains large amounts of Potassium that are made available throughout its growth cycle and cannot be washed away. In peat based soils, Potassium is quickly leached and needs to be supplemented. The result of all this Potassium is strong stems which support large, beautiful flowers!


All of Royal Gold Coco is imported from Sri Lanka and shipped to Arcata, CA where we process it with the utmost care. We understand the value of this renewable resource and know how to treat the fiber without damaging it.

How Our Organic Potting Soil is Exceptional

First, the coco bricks are processed into fine grinds with our new cutting edge equipment. Then, a unique hydration process begins which ensures the material is properly pH balanced and the salinity is at a minimum. Finally, we add the highest quality compost tea and a unique biological control that eliminates the chance of unwanted soil born bugs. These steps combined create our excellent potting soils, resulting in higher yields, better flavor, with greater consistency in finished product.

Organic Potting Soil; Coco vs. Peat Moss

There are several reasons why gardening in Coco is much better than gardening in peat based soils; First, and foremost, concern for the environment. Peat should not be seen as a sustainable product because it takes hundreds of years to form. Peat bogs also contain huge amounts of carbon- twice as much as the forest do worldwide. Once the peat bogs are dried out, the carbon is released into the atmosphere contributing to global warming. None of our natural resources have been depleted in the making of our product because coconuts fall to the ground every day. Coco coir can also be used up to five times, saving you time and money. When you are finished with the coir, simply mix into your outdoor garden or yard.

Another significant problem with peat moss mixes is when they dry out, they become very difficult to rewet. The soil then actually repels more water than it absorbs! The soil shrinks inside the pot, pulling away from the sides and damaging the roots. When coco becomes dry, it doesn’t shrink inside the pot and is easily rewet.

Basement Mix

Royal Gold Basement Mix is unlike any other potting soil on the planet! Developed through years of research, and perfected in Humboldt County, California, Basement Mix is the highest quality soil mix on the market. Each unique component has been hand selected to ensure the highest quality and consistency. Only lightly charged with organic nutrients, this mix allows the gardener to feed often, supplying all major NPK with any complete nutrient system.


Although Basement Mix was originally developed for “slow drip” or drain to waste systems, gardeners have enjoyed success using several other gardening techniques including ebb and flow or top feeding in beds or containers of any size. Royal Gold Basement Mix has also been known to grow large “smiles” throughout Northern California and Colorado!!



 Coco Fiber

Loose Coco can be used in Hydroponics, pots and containers, beds and most other growing techniques. Seedlings, cuttings, and rooted clones thrive in Royal Gold Coco! Start your plants off with a wet to dry schedule. After plants are established, feedings can increase. Root bound pots can be fed 1 to 6 times a day (depending on size of plant and size of container it is in). Be sure to feed often at the recommended application rate from any complete nutrient system. It is recommended that you use either a coco specific nutrient or supplement Calcium and Magnesium as coco soils use this at a higher rate!






Mendo Mix

Royal Gold Mendo Mix was originally developed with the dry outdoor conditions of Mendocino County, California in mind. This mix is heavily charged with organic nutrient and has greater water retention than most soils. Ready to use straight out of the bag, Mendo Mix supplies all the organic nutrition your plant will need. The sweetest tasting fruit can be achieved by using water alone. However, the highest yields have been produced by using supplements with veg and bloom enhancers. Longer season plants will require increased feedings of complete nutrient as growth increases. Some gardeners choose to “top-dress” with this mix as well. Be sure to mulch the top layer to increase water retention. Mendo Mix also works great when mixed with clays or sandy soils.


Although the Mendo Mix was designed to be used outdoors, gardeners have enjoyed success in greenhouses and indoors. Because of its superior water retention, feeding indoors will be less frequent. The size of the plant and the size of the container it is in will determine how often it will need to be watered. Royal Gold Mendo Mix will outperform all its competitors in transition, growth, yield and quality of fruit!



Royal Gold Tupur was developed with one idea in mind-Feeding the plant as much and as often as possible! This high porosity mix allows the gardener to feed often, supplying all major NPK with any nutrient system ( Cutting Edge Solutions, Botanicare, House and Garden, Advanced Nutrients, BioBizz, etc). Although it was created for “slow drip” drain to waste systems, gardeners have enjoyed success in conventional and hydroponic style gardens and in containers of all sizes. Feed 1 to 6 times a day depending on the size of your container. To decrease the feeding schedule, use a drain dish to catch run off. Decrease the fertilizer rate by 1/3 to 1/2 if there is no run off. It is also recommended that you water (pH Balanced) every third feeding. Be sure to supplement Calcium and Magnesium as coco soils use this at a higher rate. Also, adding bloom enhancers greatly increase your yield. Get Tupur!!
