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

Should I use black or white film around cocopeat?
Choose film with the growing environment and product specification in mind. Colour alone does not describe durability, temperature performance or suitability.

Why the root zone matters
The outer surface can change how the container receives solar energy. The actual root-zone result also depends on shading, airflow and exposure.
01 / OBSERVE
Three checks before you change anything
- Check which surface faces outward in the intended installation.
- Compare root-zone temperatures in representative positions.
- Confirm the film specification and installation instructions.
02 / NARROW IT DOWN
What problem are you trying to solve?
Choose the closest observation for a suggested next check.
Excess heating in exposed bags
Review shading and the intended reflective surface, then verify temperature in a trial.
Film installed inside out
Confirm orientation with the supplier before changing planted bags.
No measured temperature problem
Choose based on the agreed system specification rather than assuming one colour always grows better.
03 / TAKE THE NEXT STEP
Leave with something useful
Use measured root-zone conditions to evaluate the film in your own greenhouse.
Keep in mind
Do not promise a fixed temperature reduction based only on film colour.
