How large can they get

I am going to use this aero 20 setup for the first time. Its like an nft aero setup anyway my question is if i throw clones in and just start flowering how big will the get.. my clones are about 4-5 inches. i currently use dwc system which is fine and i just wanna try a diff setup and i have never grown small plants usually 3 to 4 footers so any comments would be great thanx...

estimate at least each clone doubling in size, however they may triple depending on strain, growing conditions, etc..

ok cause my larger plants when i flowered sometimes would get freaking huge and smoetimes not much but it could be cause they might of gotten stressed...so double huh ok im gonna wait a couple weeks let them get a little more growth thnax
