What's Denice's altitude in NM?
In 2005, I lived in SFe, where it was 7000 ft in altitude. That meant more intense sun exposure to my semps. And so it was shade cloth for the semps. Here's what DH rigged up for me to keep rodents and sun away from the semps in their flats (and using water barrels In a different way...):
Semp flats up on rain barrels but covered with shade cloth that was stretch over PVC pipe frames on hinges to lift and lower.
