Cooling a Small Greenhouse: Shade Cloth, Fan Direction, and Plant Placement

A new 6×8 ft Harbor Freight greenhouse hit 105°F. Jeff Dallas's fixes:

• Fan direction: Point box fan into greenhouse to pull cool air in; vent through roof vents.
• Shade cloth: Immediately install 40–50% shade cloth (from Lowe's/Home Depot) covering up to vents. Critical for temperature control.
• Secure panels: Double the panel clips; caulk with silicone to stop leaks.
• Plant placement: Nepenthes in shaded side; sundews, flytraps, Sarracenia in full sun side. Transition plants gradually—expect some leaf burn, then new adapted growth.
• Water: Keep very wet during transition; use trays if needed.

Plants will adapt and thrive with proper light and temperature management.
