Why do breeders list height for their genetics?

[RFheavy]

I guess what I'm really asking is what happens if I go above the specified threshold?

Don't worry you probably will if your topping your plant. Breeder's grow in ideal conditions - 3x3 tent, no topping.

yeah they kinda put all the strains thru the same conditions and veg times so when theyre done flowering they know witch ones stayed short and which ones didnt

because if you're growing in a tent with limited ceiling heights, you may want to avoid really tall plants or you have to be ready to spend a fair bit of time training it. you can always grow it bigger. unless it's an auto of course.
