Frequently Asked Questions
What mil thickness do I need for greenhouse tarps?
For season-long greenhouse use aim for 6 mil continuous poly at minimum, or 11–15 mil PVC for better insulation and puncture resistance. Thicker materials retain heat and handle wind better but are heavier to install.
Will a clear tarp cause overheating in my greenhouse?
Clear tarps transmit more light and can increase midday temperatures. Use shade cloth, roll-up sides, or a translucent/diffusing tarp to prevent hot spots if overheating is a concern.
How do I reduce condensation on my greenhouse tarp?
Improve ventilation (vents, vents at ridge, roll-up sides), use diffusing/translucent covers to reduce large droplets, and avoid direct contact between warm plants and cold surfaces. No tarp eliminates condensation—management and airflow are key.
