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.

Why does a cocopeat crop slow down in cool weather?
Review root-zone conditions alongside light and air temperature.

Why the root zone matters
A watering programme that worked in warm bright weather may not suit a cooler crop.
01 / OBSERVE
Three checks before you change anything
- Compare root-zone temperatures through the day
- Track how long bags remain wet
- Review light and crop stage
02 / NARROW IT DOWN
What changes most?
Choose the closest observation for a suggested next check.
Media remains wet longer
Reassess irrigation against current demand.
Low light dominates
Review crop expectations and climate together.
Growth declines despite suitable conditions
Investigate nutrition and root health.
03 / TAKE THE NEXT STEP
Leave with something useful
Compare records from a healthy period with the cool-weather period.
Keep in mind
Do not increase fertiliser merely because growth has slowed.
