Bog Earth Making Turtle

I just wanted to show off my first simple Bog Earth making program I made that I thought others might find useful.

Needs a specific setup

To the right of the turtle needs to be a chest of dirt. (only full stacks no partial stacks)
Behind the turtle needs to be a chest of sand. (only full stacks no partial stacks)
A block of air below the turtle and an infinite spring of water below that block of air.
A single empty bucket in slot 6.

Code can be found here:

Any suggestions to improve it welcome.
Currently working on having same turtle make Hummus.

Suggestion - pick up some loops and make it maintain a whole lot of bog earth. Have a setup phase where it digs a trench. Supply with 2 water buckets, have it fill the trench with water. Line the sides with maturing bog earth :)/>/>

Didn't work for me. When it gets to "Starting to craft bog earth" i get "attempt to call nil"

Not,

Same thing here. Until I realized I just made a turtle - not a crafting turtle. Swap out turtles and it's a Christmas miracle - noobness removed! Good luck,
