1. Crop Steering = Total Environmental Control
Crop steering is the active management of your plants’ entire environment—water, light, humidity, and temperature. Every detail matters. If you let things happen passively without adjustments, your plants will never reach their full potential. Proper crop steering optimizes growth, prevents deficiencies, and ensures a superior harvest.
2. Understanding EC (Electrical Conductivity): A Key Indicator
EC measures the amount of dissolved salts (nutrients) in your substrate. In organic growing, EC is more complex because nutrient availability depends on microorganisms breaking down organic matter.
• Low EC = Not enough nutrients → slow growth, deficiencies.
• High EC = Too many nutrients → risk of nutrient burn.
Monitoring EC ensures that your plants get exactly what they need—no more, no less.
3. Transitioning from Vegetative to Flowering: A Critical Stage
Switching from veg to flower is like a plant moving from childhood to adulthood.
• If the environment isn’t stable (correct humidity, temperature, and nutrients), flowering may be stunted or stressful.
• Gradually increasing EC ensures plants get enough nutrients to develop dense, resinous flowers.
4. DLI (Daily Light Integral): Measuring Light for Maximum Growth
Light is your plants’ energy source. DLI tells you how much total light they receive each day.
• Too little light = Slow growth, small flowers.
• Too much light = Stress, reduced efficiency.
By measuring and adjusting DLI, you ensure that plants receive the perfect amount of energy to thrive.
5. Monitoring Runoff Volume & pH: Why It’s Essential
What your plants expel in runoff water reveals what they’re actually absorbing.
• Stable pH = Proper nutrient uptake.
• Low pH = Nutrient lockout, deficiencies.
Without monitoring runoff, you might miss problems until it’s too late.
6. Keeping a Stable VPD (Vapor Pressure Deficit): Even at Night!
VPD controls plant transpiration. A consistent transpiration rate ensures optimal water and nutrient absorption.
• High humidity at night = Mold risk.
• Low humidity at night = Dehydration risk.
Maintaining a stable VPD guarantees consistent hydration—day and night.
7. Using Technology for Precision Growing
Modern sensors and software track everything—temperature, humidity, pH, EC.
• Without technology = Guesswork.
• With technology = Real-time adjustments, fewer mistakes, better yields.
Using data-driven decisions improves efficiency and consistency.
8. Irrigation: Adjusting for Substrate Size
Small pots dry out faster than large ones.
• If using small pots, a pre-lights-out irrigation keeps plants hydrated through the night.
• Without proper irrigation, plants experience water stress, slowing growth and reducing yield.
Proper watering schedules maintain healthy plants and steady development.
9. Defoliation: Less Is More
Over-pruning can harm plant energy production.
• Leaves = Energy production via photosynthesis.
• Fewer leaves = Less energy for growth and flowering.
• Excessive defoliation = Slower growth, increased labor costs.
Only remove leaves when necessary to avoid blocking light and airflow, but don’t overdo it.
Crop Steering = Higher Yields, Healthier Plants, and More Control
Mastering crop steering allows precise control over growth phases, nutrient uptake, climate, and irrigation, leading to:
✅ Bigger, better-quality harvests.
✅ More efficient nutrient use.
✅ Stronger, healthier plants.
If you want elite-level control over your grow, understanding and applying crop steering is essential.
