Keiko's heat check. Measure your row width and match the fabric shade percentage to your climate. Check the Amazon listing for exact dimensions and material weight.

I treat a greenhouse row cover as a precise fit, not a generic sheet. The job is to match the fabric width to your bed and the shade to your heat needs.

Look at the product photo for the fabric texture and check the title for width and shade details. Ensure the dimensions match your specific row before you add it to the cart.

1. The 8 mil thickness and 16' x 25' dimensions define the structural limit of this Farm Plastic Supply sheet, which is rated for four years of UV resistance.
2. Measure your hoop house width against the 16-foot span to ensure the material can bridge the gap without excessive tension that might tear the polyethylene.
3. Check the Amazon listing photo for the roll diameter and the clarity of the film, as the 8 mil gauge is thicker than standard 6 mil options.
4. Look for the specific UV stabilizer language in the description to confirm the four-year claim matches your local sun exposure.
