To be perfectly honest I feel that some plants stretch less once they get to a certain size. The real problem that I had was I chose to veg them for almost 2.5 weeks under the 1k hps after already vegging four 7 weeks under a 400.. Didnt have a choice, but I would have done it differently if I could have. Im interested to see what you do about those four footers.. Those will def end up being 6ft plus prolly almost 6.5-7ft..
