How do I take a cutting from my plant?

I some clones from the dispensary a couple of months ago, and right from the start one of them had an extra branch growing out of the rockwool separate from the main stem. It's now gotten to the point where this branch is pretty good sized and I was thinking of making another clone out of it, but I don't know how. I was thinking of getting a cake container to use as a humidity dome since I'm only doing one and I was planning on using a rockwool cube. Can someone walk me through the process of cloning this branch so I don't mess up, I really want this to work.

sub'd. gonna do this with in the next week. always like help before diving into something i havent done before.

Cloning is very simple. Youll need rooting gel or power. Check out youtube for cloning. Very easy to do... just waiting and hoping for them to take is another thing.

I know from previous exp. that some strains clone better than others as well. Don't be disappointed if it doesn't take root. I recently had an issue with some cuttings of my Barney's 8 Ball Kush where 0% were successful. However, my cuttings from my CH9 Jack & White Widow/Big Bud did great with a 100% success rate (all of them taken at the same time). Hope this helps. Youtube is a great resource when it comes to learning how to clone. Like Flares said, it is super simple. Make sure your water is ph'ed correctly, proper temp & humidity, and you should be golden.

Peace bro
