I have fallen in live with gutter gardening! Karl and I stopped by Home Resource in Missoula - where we picked up several gutters of various lengths. Jennet and Ed are gardening with me, and they helped cut ends and I drilled holes in the bottom of the gutters. They are the ones in the lower rack.
Never being one to sit still, I went back and purchased some more. Only this time I did not drill as many holes in the bottom. The gutters along the back wall, starting at the top, are filled with lettuce, strawberries and rosemary.
Karl ordered some fans and better ventilation. I am looking forward to not having to monitor the system in person.
A friend and I are working on the Raspberry Pi, greenhouse automation as well.
As much as I would love to take the plastic down, it really helps with the temperature. The high is rarely over 76 and the low is rarely under 40. some neighbors lost their seedlings when their greenhouse reached over 100 degrees.
