m0useanswered grow question a year ago Its visually less appealing then tight indca nugs but it does not affect the quality of cannabinoids.
I have grown stuff that foxed tailed, its less dense and more airy, but still got me high. Also some breeders like the foxtail trait in their buds.
Don't worry if your plant is fox tailing a bit. Lowering temps can help control it but other times its gonna do what its gonna do.
Good Luck!
