Black mesh tarps are a very simple and cheap way to control the temperature in a greenhouse. Some gardeners put up the tarp during the hottest aspect of the day and take it down later in the day. Others leave a tarp upon a single part of the greenhouse through the season.
Temporary Outdoor Covering
Monitor the temperature in the greenhouse using a greenhouse thermometer in a house and garden supply shop. Most garden vegetables have been happiest around 70 degrees F. Cool the greenhouse using a shade tarp when it gets more than 10 degrees F over the best temperature for your crops.
Hammer four stakes into the ground at the four corners of your greenhouse. Hammer bets into the ground every 6 ft along the sides of the ground. Hammer just 1 stake at each side for smaller greenhouses.
Toss a black mesh tarp over the top of the greenhouse. Use more than one if necessary. Attach tarp into the bets with little bungee cords. Leave the stakes from the ground, and attach and remove the tarp as vital.
Apply water into the shade fabric using a hose or mister. Researchers at North Carolina State University have discovered that water evaporation in the cloth increases the shade fabric’s greenhouse cooling efficacy.
Cover or less of the greenhouse using a dark mesh shade tarp. Hammer bets only around the part of greenhouse that you wish to shade. Attach the tarp with tarp bungee cords into the bets, but leave in place for the season.
Use a shade cloth inside the greenhouse, if you prefer. Cover 1 wall having a dark, mesh tarp. Cut the tarp for fit the wall, if you prefer.
Nail hooks into the wooden greenhouse framework across the wall to be covered. Attach hooks with clips or purchase greenhouse hooks in the metal-frame greenhouse manufacturer. Hang the mesh over the hooks.
