Viragrow does not have a specific container soil. We have other soils we carry, or can make, but several different kinds of container soils are not one of them. Container soils are varied and should be made differently depending on their purpose.

The first question that should be asked is what you will do with the container. What will it grow? Does it need to be moved around? If the container is not ever going to be moved then that’s easy. Use our Garden Soil Mix. It’s on the heavy side but you can lighten it so you can move the container around if that is needed.

Let’s say you want to occasionally move the container around. Then these soil mixes might be a bit heavy depending in the size of the container. Mix our perlite with it. We have the best price on perlite in or around Las Vegas and perlite is lightweight. Mix no more than one third of the volume of the container with perlite. If you are not sure which type of perlite to use, try looking at Grade #3 perlite.

Try using about 20 to 30% of the volume of the container in perlite. Then pick the soil mix you prefer and mix the two together. The soil mix will add plant nutrients to the container for plant growth. The perlite will lighten the container soil mix up considerably so the container can be moved. You can use more perlite than that if you want. It’s inert so it will not affect your plants at all. In fact, you can grow plants in 100% perlite but it would be a hydroponic substrate so you would need to figure out which fertilizer to add on a regular basis.

Oh, and by the way, Viragrow also carries water soluble fertilizers as well at very reasonable prices.
