Well "/hebe/" is terrible name for a board about horticulture. You seem to underestimate the last board that used this name
1)CP Spambots about have bookmarked this adress and they will try post here every day forever. . It will be years before Hotwheels can implement a working solution. An imageboard without images loses it's purpose.
2)Hebeophiles expecting old content will be here
3)People actually intrested in horticulture will avoid this place thinking of it as a "pedo playground".
How about "/plants/", "/veggies/" or "/plantae/" instead?
If instead you are just keping this board name for a secret different purpose nevermind what I said.
