Antifragile - Genuine Cannabis Supersoil



Genuine Cannabis super soil

A fully enriched living soil formulated for the pure organic grower. All essential plant nutrients are provided by this complete soil ecosystem through the vegetative and flowering phases, covering the plant's full life cycle. The continuous nutrient release processes are dependent only on microorganisms, plant roots and the addition of clean water. The holistic nature of natural ecosystems is to improve with time, making systems antifragile in response to challenges. The antifragile system regenerates itself continuously.

The Antifragile supersoil is a fully loaded living soil with immediate-, medium- and slow-release sources of natural organic plant nutrients.

Nutrient toxicity can occur due to the high nutrient content of super-soils such as the Antifragile Craft Soil. Especially directly after transplanting. The high nutrient content of a super-soil should cover all nutrient requirements of the plant through both the vegetative and flowering phases. Especially for plants that can handle the Antifragile super-soil at full strength.

Some important points regarding toxicity issues (Mainly for Indoor cultivation):

  • Cannabis strains range widely in terms of their nutrient requirements and uptake
  • Many strains will show toxicity issues in the Antifragile super-soil after transplanting
  • Cannabis under indoor cultivation conditions are much more susceptible to nutrient toxicity due to the lower environmental intensity
  • Plants grown in high intensity* indoor facilities will have less or no issues
  • Start with testing the Antifragile super-soil by using half Antifragile soil and half Classic soil
  • Do no use for plants 4 weeks and younger, use the Freedom Farms seed starter
  • Add the two soil layers separately in either bottom/top order as long as the roots start off in the Classic soil half
  • With first watering allow for some good runoff (more important for a full strength Antifragile grow)
  • Give it time (1 week) for plants adapt to a strong soil. Observe new growth tips.
  • Apply a 50% runoff-flush if symptoms persist in the newest growth after 1 week
  • Do not add nutrients to rectify symptoms
  • If you have a good system don’t change everything to a new soil immediately
  • Get familiar with a new soil by starting small and noticing which strains do well in a particular soil under your unique growing conditions
  • Outdoor cultivation performs very well on full strength (i.e. 100% soil volume Antifragile)
  • Remember to read the info on the back of the Antifragile soil bag
  • Recommended products with the Antifragile soil: Malted Barley (feed your soil and earth worms), Alfalfa Mulch (keep your top soil moist in outdoor applications) Mycorrhizal Fungi (transplanting), Fulvic Acid (efficient uptake of nutrients) and Blackstrap Molasses (complex carbohydrate feeding your microbial population)
  • Ideal for fabric container growing
  • Indoor, Greenhouse or Outdoor cultivation
  • Raised bed system re-planted over multiple cycles (No-till, cover crop)
