The short version

  1. Rates

    At the root:
    Use the rate on your bottle's label.
    As a foliar:
    Use the rate on your bottle's label.

    These come from the current label. If this page and your label ever disagree, the label wins.

  2. Mixing order

    For any silicate, dilute it in water and mix well before adding cal-mag. Follow the Cryo Sil label for rate and mixing.

  3. Storage

    Follow the storage directions on your bottle's label.

What is in the bottle

Cryo Sil is 0-0-1.5. The label also declares 4% soluble Si from potassium silicate and 9% carbon. Derived from potassium silicate and a safflower and hibiscus ferment. Root and foliar.

What to watch

Not a marketing promise. Watch how the product behaves in your actual system: storage, mixing, reservoir clarity, irrigation hardware, and the crop itself. If you chose trial emails, Nik will email about a week after delivery to ask what you noticed. A person reads the replies.
