Grower Glossary – ZUpdated 8 days ago

Z

Zeolite

A natural mineral with high cation exchange capacity (CEC), used in soil mixes to retain nutrients and improve aeration.
Grower Slang: “Rock sponge.”
Cronk Tip: Add small amounts to soil or coco to increase buffering and reduce nutrient leaching.

Zero Runoff (Hydro Term)

A precision-feeding technique where no nutrient solution drains out of the pot — all is absorbed by the plant.
Grower Slang: “Closed feed.”
Cronk Tip: Best for automated irrigation; monitor EC closely to prevent salt buildup.

Zero Waste Grow

An eco-conscious cultivation method minimizing waste, reusing media, and recycling nutrients.
Grower Slang: “Closed-loop.”
Cronk Tip: Pair PuurOrganics with compost and microbial teas for a regenerative zero-waste system.

Zeta Potential

The electrical charge that influences how nutrient particles interact in solution.
Grower Slang: “Mix charge.”
Cronk Tip: Proper pH balance prevents nutrient precipitation and ensures full bioavailability.

Zinc (Zn)

An essential micronutrient involved in enzyme production and chlorophyll synthesis.
Grower Slang: “Micro metal.”
Deficiency Symptoms: Twisted new leaves, interveinal yellowing.
Cronk Tip: Chelated zinc in Cronk Micro ensures uptake across a wide pH range.

Zinc Deficiency

A lack of available zinc leading to stunted growth and leaf distortion.
Grower Slang: “Twist fade.”
Cronk Tip: Apply micronutrient blends or foliar spray for rapid correction.

Zkittlez (Cannabis Strain)

A legendary indica-dominant strain known for fruity aroma and colorful buds.
Grower Slang: “Z,” “Z strain.”
Cronk Tip: Maintain 22–25°C during bloom to preserve candy-like terpene profiles.

Zaza (Cannabis Slang)

Slang for top-shelf, high-quality cannabis with strong flavor and potency.
Grower Slang: “Fire,” “loud.”
Cronk Tip: Achieve Zaza-level quality with proper flushing, low humidity in late flower, and post-harvest curing.

Zip (Cannabis Slang)

A slang term for one ounce (28 grams) of cannabis.
Grower Slang: “O,” “zone.”
Cronk Tip: When tracking yields, note total “zips per light” to measure harvest efficiency.

Zone (Root Zone)

The area around plant roots where nutrient absorption and microbial interaction occur.
Grower Slang: “Root zone,” “rhizo.”
Cronk Tip: Keep your zone oxygenated — use Monkey Juice for healthy microbe activity and root vigor.

Zoned Out (Slang)

Describes a heavy, sedative high or relaxed mental state after consuming potent cannabis.
Grower Slang: “Couch lock.”
Common with high-THC indica strains or overripe harvests.

Z-Strain

A slang reference to cannabis cultivars derived from or inspired by Zkittlez genetics.
Grower Slang: “Z cut.”
Cronk Tip: Z-strains often produce heavy terpenes — ensure low drying temps (18–20°C) to retain aroma.

Zymase

An enzyme complex that converts sugars into alcohol during fermentation.
Grower Slang: “Ferment enzyme.”
Relevant in composting, brewing compost teas, or microbial breakdown processes.

Zymology

The scientific study of fermentation.
Grower Slang: “Ferment science.”
Cronk Tip: Applies to organic growing and microbial brewing — understanding zymology improves compost tea quality.

Zygote

A fertilized cell formed by the fusion of male and female gametes (pollen and ovule).
Grower Slang: “Seed start.”
Cronk Tip: Every cannabis seed begins as a zygote — stable parent genetics ensure uniform offspring.

Zygomorphic Flower

A flower with bilateral symmetry, common in many angiosperms.
Grower Slang: “Mirror bloom.”
Mostly a botanical curiosity, but important in strain morphology and breeding identification.

Zygosity (Genetic Term)

Describes whether alleles for a gene are identical (homozygous) or different (heterozygous).
Grower Slang: “Gene match.”
Cronk Tip: Breeders track zygosity to stabilize traits like color, flavor, or cannabinoid ratio.

Zonal Leaf Chlorosis

Localized yellowing in specific leaf zones caused by nutrient imbalance or pH drift.
Grower Slang: “Striped fade.”
Cronk Tip: Calibrate pH and check micros — manganese or zinc are often the cause.

Zonal Growth

Uneven plant development caused by light, airflow, or nutrient distribution issues.
Grower Slang: “Hot spots.”
Cronk Tip: Rotate plants and ensure even PPFD and airflow to eliminate zones of stress.

Zombie Bud (Slang)

Term for bud left on the plant too long, degraded in potency or aroma.
Grower Slang: “Overripe,” “sleepy weed.”
Cronk Tip: Harvest at cloudy-to-amber trichomes — too late leads to sedative effects.

Zoom Lens (Grower Photography)

Camera lens used to capture detailed macro shots of trichomes or pest inspection.
Grower Slang: “Bud lens.”
Cronk Tip: Great for tracking trichome maturity or deficiency symptoms.

Zone Heating

Localized temperature control in sections of a grow room.
Grower Slang: “Heat zones.”
Cronk Tip: Use thermostats or infrared heaters to maintain even canopy temps in large spaces.

Zeta Filter (Water Filtration)

A fine filtration method that uses electrostatic attraction to capture particles smaller than standard filters can.
Grower Slang: “Charged filter.”
Cronk Tip: Perfect for pre-RO filtration — removes colloidal solids that cloud solutions.
