Whoa! I take a 2.5 day tech vacation and the thread explodes!
Sounds like we have a bit of clone talk to do so lets start there.
To address the issue of how to use clone gel, where to take cuttings from etc. First off, use clonex. It's mild acid formula makes cuttings soft and you can't really over do it so its ease of use is excellent.
Clippings should always be taken before the plant is scrog'd, wasting electricity and time vegging a giant bush that turns out to be a male is beyond bad news. the first clone to root should be put into flower immediately to tell sex, as soon as it shows discard it and make sure to use its sister clones for your next run.
Take all your clippings from the lowest and greenest branches you can, the more "woody" the branch, the longer it takes to root. The closer it is to the bottom the more rooting hormone the branch has and faster it will root as well.
The end all be all in cloning is to use an aero-cloner, there are many sites that teach you how to build one and they are the fastest way of making clones. You don't need clonex or anything other than a timer set to 15 min on 15 min off, the clones are forced to root quickly because they only humidity they get comes from the sprayers inside the cloner, you basically leave them and come back a week later to fully rooted plants, ready for vegging.
Now for the comments on all the "show and tell" I missed.
Lillidian, I'm lovin' your grow, sub'd a while back. Avoid vertical grows, apical dominance (earlier forum discussion) killed my yield. The highest buds got nice and thick and the bottom was pop-corn. I won't do another vertical grow, it was a waste, I think I pulled a little over 10oz off 2 plants and thats unacceptable even fr a 400w.
Mr.green, can't see the edge of your screen in that pic so hard to tell how close you are but you definitely have a couple weeks. get the screen 80% full then veg for a few days without training, then flip, if you need to train after that fine but give them a couple days into flowering so you can see what branches are getting taller. I tend to take the tallest branches during the first 2 weeks and bend them so the other branches can catch up, what you end up with is a very dense and uniform canopy of compact colas.
Luv2grow, your setup is looking great! I'm super impressed, flowers are looking really tight and heavy, love it!
