Choose by condition, not a product label

Use this table to identify the decision that comes first. It is a selection framework, not a substitute for the product manual, supplier quotation, structural assessment or local requirements.

What to verify before purchase or installation

Decision boundary

Material names and headline specifications do not establish a complete greenhouse outcome. Verify product-specific limits with the current manufacturer documentation and confirm structural or permitting requirements locally.

Common questions

Is 6 mil plastic good for a greenhouse?

6 mil is a common thickness category, but suitability depends on the product's stated treatment, weather exposure, frame and service expectations.

Should I buy clear or diffused greenhouse plastic?

Start with crop layout and light objective. Use product-specific light data, not a broad material label, to make the comparison.
