			I just sent an email, and am posting here to check if you got an email by Alejandro Andreu, (i think they also did a wiki account request)

			(Also for future notice i guess, what is the best way to contact you? I know i tend to mainly check my "work" email when at my desk, but otherwise don't see it as much, but check discord mobile more, so that tends to be a better way to reach me when i am not at my desk)

			==Robotic Grillo walk-behind tractor==
			Perhaps it is possible to make an implement for the [https://www.earthtools.com/bcs-grillo-comparison/ Grillo walk-behind tractor] to give it one or 2 extra wheels, and automate the whole tractor ? The PTO shaft can either be extended or the extra wheels and robotic control can be made to attach after the implements. Not sure what software can be used to control the agricultural robot, perhaps ROS ?

	Also, a benefit over the gutter system with soil which I mentioned is that replacing the soil with other soil with compost in it (after a growing season) is quite ~~laborious~~, so this modular hydroponics system has that as a benefit. Downside however is that there is a higher cost compared to that so I suggest to keep the whole system as simple as possible (the growers using this aren't professors or experimenters). Also, the system should be constructed using readily available components, found in shops (no custom-designed components, unless just as upgrades, keeping the basic system just composed from readily available hardware store/hydroponics suppliers components).
