Plants & climate
Humidity, heat and watering
Read temperature and humidity together. The same relative humidity at different temperatures does not create the same drying demand on a plant.

Should I reassess cocopeat management after changing shade screens?
A screen change alters the crop environment. Review the root-zone observations before carrying on with every previous setting unchanged.

Why the root zone matters
Changes in light and heat can affect plant demand while the coir’s water storage remains the same.
01 / OBSERVE
Three checks before you change anything
- Record when screens operate and what changed in their use.
- Compare root-zone moisture and plant response before and after the change.
- Check daytime and night-time conditions rather than only midday temperature.
02 / NARROW IT DOWN
What changed after screening?
Choose the closest observation for a suggested next check.
Media stays moist for longer
Review demand and management with your grower adviser using measured observations.
Plants still overheat
Check screen coverage, ventilation and root-zone exposure together.
Growth slowed without obvious stress
Evaluate light availability and crop expectations before adding more fertiliser.
03 / TAKE THE NEXT STEP
Leave with something useful
Treat screen adjustments as a reason to update the crop observations and operating plan.
Keep in mind
Do not assume cooler air automatically means every part of the root zone is correctly managed.
