Can cocopeat growbags get too hot in a greenhouse?
Measure near the roots rather than relying only on the greenhouse air reading.

Why is damage worse on one side of plants in cocopeat?
A directional pattern can be more useful than the colour of a damaged leaf. Compare the affected side with nearby light, heat and airflow sources.

Why the root zone matters
Coir root conditions may be uniform while the canopy experiences uneven exposure. The substrate should not be blamed before that pattern is checked.
01 / OBSERVE
Three checks before you change anything
- Map the damaged side relative to walls, heaters, vents and sunlight.
- Compare plants at different distances from the suspected exposure.
- Check whether root symptoms show the same directional pattern.
02 / NARROW IT DOWN
What does the pattern follow?
Choose the closest observation for a suggested next check.
A heater or hot surface
Review clearance and local conditions with the equipment operator.
A bright edge or reflective surface
Assess light and temperature exposure and compare with protected plants.
No obvious environmental direction
Investigate root distribution and plant health with an adviser rather than forcing an exposure explanation.
03 / TAKE THE NEXT STEP
Leave with something useful
Take photos that show both the plants and their surroundings.
Keep in mind
Do not change the coir blend solely because one exposed side of a canopy is damaged.
