Currently building a FarmBot for inside the first story of a corporate office.
Finding a grow bed was difficult as I am avoiding wood due to the potential leakage issues, I instead intend to use a 1m x 2m plastic tub with premade drainage points.
The tub is very deep so am wondering how best to fill it with empty space so I don’t need a crazy amount of soil (and weight!). I am thinking that additional plastic containers placed inside the bin before soil might be a good bet. (I can stand on the containers and weigh 100kg so I think the soil weight will be just fine).
What might the minimum grow depth need to be? My container is 570mm deep and I was considering dropping in containers that are 290mm tall leaving a soil depth of 280mm deep – will that be deep enough?
I see in the build guide that when attaching the rails to the edges of a wooden raised garden bed, that it is done on the outer edge of the wood.
In my case the edges are plastic and are quite thick, appx 65mm-70mm. Would I be wiser to install the tracks on the inside of the plastic tub?? Or can the farmbot software accomodate for different sized grow areas independently of the track width?
