how big would these get o.0

i currently have 2 mother clones of some unknown sativa all thats known is its some early pulling good tasting strong high strain. mother # 1 is about 3ft, mother #2 about 2ft im running out of time to get my cuttings, but i had a crazy idea instead of getting cuttings to just let the 2 plants keep on vegging till there about 5ftish then put them out side how big do you think that would end up getting. or should i just get started on cutting some clones and put out a good 20 of them.

cut clones. and plant

Just take 5 clones from each and throw them outside, those could be 10ft maybe bigger. Given the right growing spot,,,,,,,,,,wow that would be in Oct
