Hi I have an idea to reduce the time spent in my poly tunnel growing salad.
Essentially it's a roll-able carriage on rails that you slide up and down the bed. You attach different tools to it depending on what you are doing. It gives you some of the benefits of precision farming without the complex electronics.
The planting/ weeding bit should be fairly straightforward, but creating a machine (battery drill powered?) to collect the leaves will be a bit more complex.
I started writing it up here
Any thoughts, comments welcomed.
