Part 12-Finish Prep for the Greenhouse? And a really bad water tank adventure, sort of..
What is the major contaminant from a St. Gobains Certainteed roof? Pollen!! We estimated a 0.1 inch rain. Length of shop is 62 feet. Width of shop is 25 feet. With overhang, one side is actually about 14'. If a 0.1" rain is .00833 feet. Then I calculated 52.6 gallons hit the roof on the first rain or 62 * 14 *.0083 *7.28 to convert to gallons.Should save a lot of walking! With tank about 1/2 full I noticed a heavy yellow tinge, I assumed roofing tar, I was wrong, see pollen pictures below. Good job son John Kimble, Certainteed environmental chemist (Yea for the home team!). Also ran a test to see if aluminite used for greenhouse moisture barrier could also be used for dry markers, wow, also a hit!!
Not so fast!!!
Turns out I made a listening error, my son actually said all is OK if the shingles are not algae resistant. So today, July 23,
three months later, I actually went out to the barn to look at the wrapper on the spare shingles. I had a hint something was wrong
because several of the plants were sick including the morning glories I was going to use to shade the trees. My gooseberries, the
leaves were dying, funny, the grass was dying, I fugured maybe sun scald. And the dog was not drinking the water as enthusiastically, hmm.
Turns out we may have killed the trees, poisoned the dog, and used up a lot of resources..... The contractor from hell had struck again!!!
