Grower Glossary – JUpdated 9 days ago
J
The Grower Glossary – J blends science and slang — from juvenile plant care and Jiffy starters to joint terminology and jar curing. This section celebrates the culture behind cultivation.
Jack Herer
A legendary sativa-dominant cannabis strain named after activist and author Jack Herer.
Grower Slang: “Jack,” “The Herer.”
Known for energetic effects and spicy citrus aroma. A foundational strain for many hybrids.
Jaggies (Light Term)
Grower slang for “jagged” or serrated leaf edges, often caused by environmental stress or early pH swings.
Grower Slang: “Leaf jaggies.”
Usually self-corrects when conditions stabilize.
Jar Curing
The process of aging dried buds in sealed glass jars to preserve terpenes and smooth out flavor.
Grower Slang: “Jarred up,” “in cure.”
Cronk Tip: Burp jars daily for the first 1–2 weeks, then once weekly to maintain 58–62% RH.
Jar Humidity Pack
A small moisture-control packet (e.g., Boveda, Integra) placed in curing jars to maintain stable humidity.
Grower Slang: “Humidity pack,” “Bov pack.”
Keeps buds soft, aromatic, and mold-free.
Jarring (Post-Harvest Term)
The act of transferring dried buds into jars for curing.
Grower Slang: “Jar time,” “sealed up.”
A critical step in post-harvest flavor development.
Java Tea (Organic Grow Additive)
A compost tea blend derived from molasses, kelp, and beneficial microbes.
Grower Slang: “Microbe brew,” “tea feed.”
Boosts microbial life, root development, and soil structure naturally.
Jelly Hash
A soft, semi-liquid cannabis extract made by mixing bubble hash with hash oil or rosin.
Grower Slang: “Jelly,” “jam.”
Sticky, flavorful, and potent — often solventless.
Juvenile Stage
The early growth phase between seedling and vegetative stages.
Grower Slang: “Pre-veg,” “baby veg.”
Plants establish roots and begin rapid leaf development.
Jump-Start Feeding
A mild, early nutrient feeding given to seedlings or clones once roots appear.
Grower Slang: “First feed.”
Cronk Tip: Use Grow (Classic Line) at ¼ strength or Bonnie for autos to prevent stress.
Jungle (Grow Slang)
Refers to an overgrown canopy with dense foliage and poor airflow.
Grower Slang: “Jungle,” “overgrown tent.”
Cronk Tip: Defoliate strategically and add oscillating fans to prevent mold.
Jute Pot
A biodegradable pot made from natural jute fiber.
Grower Slang: “Eco pot.”
Promotes air pruning and decomposes naturally in soil.
Juiced (Slang)
Grower slang for a plant that’s receiving high nutrient levels and thriving under ideal conditions.
Grower Slang: “Juiced up,” “fed heavy.”
Be cautious not to “juice too hot” — overfeeding can cause nutrient burn.
Jug Feed (Hydro Slang)
Manual hand-watering using pre-mixed nutrient jugs.
Grower Slang: “Jug feed,” “jug run.”
Common for small grows or individual plant care.
J Root (Transplant Term)
When roots curl upward in containers, forming a “J” shape.
Grower Slang: “Root curl.”
Can stunt growth — prevent by transplanting before roots circle or compact.
Joint
A hand-rolled cannabis cigarette made from ground flower and paper.
Grower Slang: “Jay,” “doob,” “roll.”
Curing and trimming quality directly affect smoothness and burn.
Joint Clip
A holder used to smoke a joint without burning fingers near the end.
Grower Slang: “Roach clip.”
Joint Compound (Grower Slang – Soil)
A homemade soil mix or amendment “recipe” blended by growers.
Grower Slang: “Custom blend,” “grower mix.”
Often includes coco, perlite, compost, and dry amendments.
Joint Density (Colloquial)
Refers to how tightly buds are rolled into joints — also used metaphorically for flower density.
Grower Slang: “Tight roll,” “dense pack.”
Jockey Pump
A backup pump in irrigation or hydro systems that activates if the main one fails.
Grower Slang: “Backup pump.”
Used in commercial hydroponics to prevent downtime.
Joule (Lighting Energy Term)
A measurement of energy equal to one watt per second.
Grower Slang: “Energy unit.”
Useful when calculating energy efficiency for lighting systems.
Jump Cut (Cloning Term)
Taking a fresh clone cut from a branch tip immediately after topping or pruning.
Grower Slang: “Jump cut.”
Encourages rooting without wasting trimmed material.
Juju (Grow Slang)
Grower slang for the overall “energy” or vibe of a grow space — a mix of good environment, microbes, and care.
Grower Slang: “Good grow juju.”
Cronk Tip: A clean, well-loved space grows better plants — and fewer problems.
Junk Nutrients (Slang)
Grower slang for low-quality or poorly formulated fertilizer that causes salt buildup or deficiency.
Grower Slang: “Garbage feed,” “junk juice.”
Cronk Tip: Use professional-grade nutrients with consistent chelation (like Cronk’s Classic or PuurOrganics lines).
Jury Rig (DIY Grow Term)
An improvised setup or repair using what’s available.
Grower Slang: “MacGyvered,” “makeshift fix.”
Fine for quick solutions — but don’t rely on them for electrical safety or irrigation long-term.
“J” represents journey — from juvenile growth to jarred perfection. Keep your post-harvest quality high with proper curing, airflow, and Cronk drying techniques.
