You can harvest them all at the same time....but they will all finish individually. Most likely not enough to make a difference but each is their own little individual. Now doesn't that make you feel like a proud parent?

I personally love Stinky's method of turning the RR over and cutting a straight hole in it for clones. For seeds I use the pre-made hole but for cuttings I love turning them over. Makes my clones stand up straight because of the way the RR's are shaped and I like that fungus fighting stuff kissing right up next to my clone stem.

Sorry.....got a little kinky there.....
