Core Growing Concepts
- Microgreens
- Young vegetable greens harvested just after the first true leaves appear.
- Hydroponics
- Growing plants without soil using nutrient-rich water.
- Soilless Growing
- Any growing method that doesn’t use soil (e.g., coco coir, rockwool, water).
- Substrate / Growing Medium
- Material that supports plant roots (e.g., coco coir, rockwool, peat).
- Seed Density
- How many seeds are planted per tray or growing area.
- Germination
- The process of seeds sprouting into seedlings.
- True Leaves
- The second set of leaves that look like the mature plant.
- Cotyledons
- The first leaves that emerge from a seed (seed leaves).
- Harvest Window
- The ideal time range to harvest for best yield and quality.
- Yield
- The amount of crop produced (e.g., grams per tray).
Hydroponic Systems
- NFT (Nutrient Film Technique)
- A system where a thin stream of nutrient water flows over plant roots.
- DWC (Deep Water Culture)
- Roots are suspended directly in oxygenated nutrient water.
- Ebb and Flow (Flood & Drain)
- Plants are periodically flooded with nutrient solution, then drained.
- Drip System
- Nutrient solution is dripped onto plant roots.
- Aeroponics
- Roots are suspended in air and misted with nutrients.
- Aquaponics
- Combines fish farming with hydroponics; fish waste feeds plants.
- Hydroponic Tower
- Vertical growing system where plants are stacked upward.
- Channel (NFT Channel)
- The horizontal pipe or tray where water flows in NFT systems.
- Reservoir
- Tank that holds nutrient solution.
- Pump
- Moves water from the reservoir through the system.
Farm Design & Structure
- Plant Site
- A single position where one plant grows (e.g., one hole in a tower).
- Tray
- Flat container used to grow microgreens.
- Rack System
- Shelving unit used for vertical stacking of trays.
- Grow Area
- Total space used for cultivation.
- Floor Plan
- 2D layout of the farm or grow space.
- Digital Twin
- A virtual version of your real farm used for tracking and management.
- Batch
- A group of plants grown together at the same time.
- Recipe (Grow Recipe)
- Standard settings for growing (light, nutrients, timing, etc.).
- Crop Cycle
- Time from planting to harvest.
- Throughput
- How much product your system produces over time.
Lighting
- LED Grow Light
- Artificial light used to support plant growth.
- PPFD (Photosynthetic Photon Flux Density)
- Amount of usable light reaching plants.
- PAR (Photosynthetically Active Radiation)
- Light spectrum plants use for photosynthesis.
- Lux
- Measurement of visible light intensity (less accurate for plants).
- Light Cycle / Photoperiod
- Hours of light vs darkness per day.
- Light Intensity
- Strength of light hitting the plants.
- Light Height
- Distance between light source and plant canopy.
Nutrients & Water
- pH
- Measures how acidic or alkaline the water is.
- EC (Electrical Conductivity)
- Measures nutrient concentration in water.
- TDS (Total Dissolved Solids)
- Another way to measure nutrient levels (ppm).
- Nutrient Solution
- Water mixed with essential plant nutrients.
- A/B Nutrients
- Two-part fertilizer system mixed separately to avoid reactions.
- Macronutrients
- Primary nutrients plants need (N, P, K).
- Micronutrients
- Trace nutrients needed in small amounts (iron, zinc, etc.).
- Water Temperature
- Important for root health and oxygen levels.
Plant Health & Management
- Damping Off
- Disease that kills seedlings early due to fungi.
- Mold / Mildew
- Fungal growth caused by high humidity and poor airflow.
- Airflow
- Movement of air to prevent disease and strengthen plants.
- Hardening Off
- Gradually adapting plants to outdoor conditions.
- Harvest Cut Height
- The height at which microgreens are cut during harvest.
