Quite the operation from your grow journal that I couldn't wait a day for all those huge pictures to load. Might want to use a lower resolution on your camera or phone or like me resize your pics on the computer before uploading to reduce the file sizes. I get nice, clear pics that go from 200 - 500k each.
For a big RDWC grow like yours those coolers are a neater solution for insulating the nutes than wrapping pails in insulation like I do with my little DIY chiller/tub DWC grow.
