all in a line

Now Homer has all 40 rain barrels lined up..and it is raining. One inch of rain will fill all 40 with a total of 2,000 gallons..that will then be gravity fed to the beds. 40 barrels, 40 bays on the greenhouse, 40 growing beds.
Notice the valves at the bottom of each rain barrel..soon there will be drip tape to the growing beds from there. and the orange and silver object at the end of the greenhouse? the Row Toe Tiller Homer designed and built this year, pictures to come..
