Test Green House for 16 Weeks

In order to guarantee the quality of the Greensafe Greenhouse, we conducted the following long-term winter test with XL model

Test duration: 16 weeks.

Location: Open yard space facing south to provide more direct sunlight.

Storm strength: Wind speed variations of 35-50 mph caused no damage to the GreenSafe!

Snow: The load of 1 ft. (30 cm) of wet snow on top of the GreenSafe left a minor indentation of only 2-3 cm with 90% of the snow sliding off the top.

Frost: With the frost-guard activated and an outside temperature of minus 8°C, the inside temperature of the Greensafe did not get lower than 4.5°C.  The frost-guard activates every 32 minutes automatically and stays activated for a period of just 3.5 minutes.  This keeps your electrical consumption down to only about 0.8 KW/h in 24 hours.

Sun: On sunny days with temperatures above 10°C, the vent hole and the door should be slightly opened in order to prevent heat build-up inside the GreenSafe.  Since the two PVC layers are resistant to aggressive UV radiation, we observed no "sunburn" on the plants.

Setup and dismantling: Inflation with the electric air pump was done in a few minutes, as was the dismantling of the GreenSafe after the 16 week test.

Fungal infestation: We noted no mold or fungal infestation inside GreenSafe.

Climate: High humidity, therefore no risk of Spider Mite infestation.  Watering of plants was only necessary every 2 to 3 weeks.  We found the Oxygen/CO2 content in the GreenSafe greenhouse to be well balanced.
