It's the iPad, trying to figure the picture taking out on it, lol. Don't have the laptop set up so can't use the camera and upload as the iPad doesn't work with that.

Yup, that's exactly what I am saying. It has gotten worse over time, apx. 4 years since build now. Take a look at pictures here: http://mikesommer.com/gallery2/v/day1/album_001/ Here is a link that might be useful: Plaster discoloration pictures of Tahoe Blue

For anyone interested, this is a picture from my greenhouse in the last week. That's Arctic Star and some new potted grapevines. All my grapes are being replaced due to virus infection. I'm replacing the reflective Extenday fabric on the ground. I think this really adds to the light levels in the canopy increasing yield potential and probably brix. I'm hoping to figure out how to post more pictures. Thanks to my buddy the green guy.
