Hey Herb,

Now I understand where this idea is comming from. Thanks, you're right others have seen it too like ZZ. I would not buy into it unless I ran my own experiment, preferably side by side grow chambers or there was some science behind it. Hey Herb do it and see what happens. But what are you going to judge it by?

Your plants look good, I would not screw with the photoperiod.
The only way to insure uniform growth is to use clones from the same mother, and even then you can have some variation because location of the cuts or just how that one decides to act.

Continued good growing to ya.
OM
