Why would you need a program to do So? I'm sure plenty of people could help you out. It's not all that tough to design when you have what available space you can use. How much power can you run. How many plants in the area. What kind of lights would you like to run.
Just use sketchup, lots of components you want are already in the searchable database.
Do a tutorial or 2 on youtube, it's really easy compared to say, DANCAD on DOS.
i used sketcup, heres my build https://www.rollitup.org/t/full-build-of-building-and-grow-by-newb.954316/, i didnt setup my buckets etc in there which i should have, would have helped with space management etc, but ended up winging it and getting it right. but yes sketchup is pretty awesome, takes a day to learn it, maybe..
