What is hydroponics?*

Growing plants in soil with added nutrients

Growing plants in water-based nutrient solutions without soil

Growing plants outdoors in greenhouses

Growing plants using only organic fertilizers

Which nutrients are the three primary macronutrients plants need?*

Nitrogen Phosphorus Potassium

Calcium Magnesium Sulfur

Iron Zinc Manganese

Carbon Hydrogen Oxygen

What does pH measure in hydroponics?*

Nutrient concentration

Water temperature

Acidity or alkalinity of the solution

Oxygen levels

What's the ideal pH range for most hydroponic plants?*

4.0-5.0

5.5-6.5

7.0-8.0

8.5-9.5

Which hydroponic system continuously circulates nutrient solution in a thin film?*

Deep Water Culture (DWC)

Nutrient Film Technique (NFT)

Ebb and Flow

Drip System

What's the difference between EC and TDS?*

EC measures temperature TDS measures nutrients

EC measures electrical conductivity TDS measures total dissolved solids

They are exactly the same thing

EC is for pH TDS is for nutrients

What typically causes nutrient burn in plants?*

Too little water

Too much light

Nutrient solution is too concentrated

pH is too low

How often should you typically change nutrient solution?*

Daily

Every 1-2 weeks

Monthly

Only when plants look sick

What's the most common cause of yellowing leaves in hydroponics?*

Too much water

Nitrogen deficiency

Too much light

Root rot

How do you prevent algae growth in hydroponic systems?*

Add more nutrients

Block light from nutrient solution

Increase water temperature

Use distilled water only

What causes root rot and how do you prevent it?*

Too much light - use less lighting

Poor oxygenation and overwatering - ensure proper aeration

Too many nutrients - dilute solution

Wrong pH - adjust to 7.0

Which indicates nutrient deficiency vs overfeeding?*

Yellow tips = deficiency Brown tips = overfeeding

Brown tips = deficiency Yellow tips = overfeeding

Both look exactly the same

Only soil plants get nutrient burn

What do red and blue light spectrums primarily do for plants?*

Red for roots Blue for leaves

Red for flowering Blue for vegetative growth

Red for heat Blue for cooling

No difference between colors

Which growing medium retains the most water?*

Rockwool

Perlite

Clay pebbles

Coconut coir

In which growth stage do plants need more nitrogen?*

Seedling stage

Vegetative growth stage

Flowering stage

All stages equally

Which topics would you like to learn more about?

pH and nutrient management

System troubleshooting

Plant diseases and pests

Lighting and growth optimization

Advanced growing techniques

Automation and smart systems
