Fundamentals
Growing plants in water instead of soil.
What is hydroponics?
The part of the plant that absorbs nutrients and water.
What are roots?
Hydroponics saves this key resource the most compared to soil farming.
What is water?
The process plants use to turn light, CO₂, and water into glucose.
What is photosynthesis?
This is the location where the substrate is stored.
What is the resovoir?
This measurement tells us if the solution is acidic or basic.
What is pH?
The strong structure that supports the plant and moves water upward.
What is the stem?
A big advantage — hydroponics lets us grow food in places without this.
What is soil?
The gas released during photosynthesis.
What is oxygen?
This system is best for large fruiting plants like tomatoes and peppers.
What is the VCS?
This tool is used to check the concentration of nutrients in solution.
What is an EC meter?
The colorful part of many plants that helps attract pollinators.
What is the flower?
Hydroponics can be used in this type of location.
What is anywhere?
This macronutrient is most important for leafy green growth.
What is nitrogen?
NFT stands for this hydroponic method.
What is Nutrient Film Technique?
The mix of nutrients and water that we use in hydroponics instead of soil.
What is the substrate?
The green pigment in leaves that captures light.
What is chlorophyll?
Plants often grow faster in hydroponics because they don’t waste energy doing this.
What is searching for nutrients in soil?
What is the optimal EC range for nutrients?
What is the optimal pH for the substrate?
What is 6.3?
Hydroponics uses this much less water compared to traditional soil farming.
What is up to 90% less?
This tissue carries sugars made in photosynthesis throughout the plant.
What is phloem?
One disadvantage of hydroponics compared to soil farming.
What is higher risk of infection/infestation?
The three plant essential nutrients introduced into the substrate
What is nitrogen, phosphorous, and potassium?
If the pump in an NFT system fails, roots quickly do this.
What is dry out / wilt?
