• Someone told me that you do not need anything other than Scientific Soils Professional Growers’ Mix or Gardeners’ Mix to grow a plant from start to finish–is this correct?
    That’s right. Scientific Soils Professional Growers’ Mix or Gardeners’ Mix + plant + water = success. We are the first to introduce the “just-add-water” concept, despite claims being made by other companies. The most common problem we encounter is growers not being able to resist the temptation to add bottled nutrient to their plants. We urge you not to do this.

  • Do I need to water with distilled or reverse osmosis purified water?
    Not unless you are on well water or know of some special circumstance with your water supply that would require this. Most tap water is perfectly fine to use, although we cannot guarantee the quality of your water. Hard water will eventually cause pH and lock-out problems. If you are in doubt, use distilled or RO water.

  • What is the base composition of Scientific Soils products?
    The base is peat, coir and perlite in the case of the Professional Growers Mix and peat, coir and cypress chip in the case of the Gardeners Mix.

  • I have been growing my plant in this soil for about 18 months then it just up and got sick, what’s going on?
    The soil is spent. The plant has consumed all of the available nutrition (or all of at least one critical nutrient) from the soil or it has undergone a pH crisis. You can add some dolomitic lime to bring the pH back up and see if that works, but you should probably just repot.

  • Why is Scientific Soils better than the competition?
    We have painstakingly refined this product over years of in-the-grow-room testing. We designed it for our own use, to save labor and to provide a consistent end product. Nobody produces a more consistent, exactingly blended product. It is the same product every time. Growers need to know their baseline. The moving targets provided by inferior mixes are just a recipe for more work and unhealthy plants.

  • Will Scientific Soils produce a more potent product?
    After a plant is provided with all of the nutrients and conditions under which it needs to grow, the rest is up to the plant’s genetics. Our competition would lead you to believe otherwise, but this claim is for the gullible. Scientific Soils will provide your plant with the optimal nutrient profile and it will make your life easier, but no soil can turn a sow’s ear into a silk purse.

  • Why should I use soil instead of an all-coco coir mix?
    Coconut coir, while useful as a structural amendment in soil mixes (we use it), is not an ideal growing media by itself. This is because coconut coir has a tendency to retain salts. Look at an all-coco grower’s older plants and you will see that they have yellowed from media sourness (acid root environment) or spotted (salt toxicity).

  • Are coconut coir and peat sustainable?
    Yes. Companies selling coconut coir often brag that it is sustainable while peat is not. In fact, both are renewable and both are sustainable. Canadian peat (which is what we use) is sustainable. Only a fraction of one percent (.02) of the peat land (bog) in Canada is harvested, and they have an effective restoration method. They remove the living sphagnum from the top, harvest, re-level and then replace the top layer of sphagnum and the bog resumes growth.

    This is in addition to recording the flora and fauna present and ensuring the drainage is as it was before the removal of the peat. All of this is conducted under supervision of local environmental groups–per Canadian law. Because of the tiny area that is harvested in relation to the amount that is not harvested, the rate at which it is removed is in pace with the rate at which it accumulates. That is the very definition of sustainability.
