Frequently Asked Questions
Are clear tarps safe for seedlings in summer?
Yes — clear tarps let most visible light through so seedlings keep photosynthesizing. In very hot, direct sun you may need to add shade cloth or partially vent the enclosure to avoid heat stress and leaf scorch.
What thickness (mil) should I choose for a greenhouse tarp?
For seasonal or temporary use 10–12 mil polyethylene is economical. For year-round protection and better tear resistance choose 14–20 mil PVC/vinyl. 20 mil is a good choice where wind, snow or frequent handling are expected.
How do I prevent my tarp from tearing at the grommets?
Use reinforced edges or triangular corner sleeves, space grommets closer together on high-wind sides, and distribute tension across multiple attachment points. Adding backing plates or using tape reinforcement at grommets will reduce seam stress.
