Okay folks, time to get this road on the show!
Timeline: The goal is to finish up the tutorial with my current grow, which will be finished in around 5 weeks
Unless everyone has an issue with it I am going to skip over a tutorial on germination. I figure at this point everyone knows how to germinate a seed and more than likely have their own method of doing so; either paper towel and baggie or 'putting' the seeds directly into their growing medium for germination. If anyone has any questions regarding germination, let me know and I will be happy to address them, otherwise, we'll consider the topic covered.
For those who have not read
NebulaHaze 's tutorial on modified manifolding I think you will find it very helpful and inline with what I am going to cover. There is a good chance that much of the information will be in Nebula's tutorial as well - but in a different way that will make it easier for you to understand. The tutorial can be found HERE ->

While this tutorial will work for any cannabis strain, you will have better results with strains whose leaf nodes are closer together or with strains specifically bred for large bud packs (e.g.; White Fire OG x Big Bud).
Keep in mind this tutorial and method is specifically for indoor growing under lights.
The initial training begins fairly early in a young plants life and you are 80% done within 4 weeks. This method or any High Stress Training (HST) should only be carried out on healthy and thriving plants. For your sake, and plants, never start hacking away at a plant that is struggling just to stay alive.

You are going to veg your plants for the standard 8 weeks before kicking them into flower. Start with a good healthy young plant. I know growers, who in an effort to keep the plant 'as natural' as possible, use 4 to 6 hours of darkness to their 24 hour vegetation cycle. You are free to do as you like, but during vegetation mode, it's perfectly safe for your plants to have 24 hours of light as darkness is NOT required UNTIL you are ready to kick your girls into flower. My personal preference is for 24 hours of light during vegetation.
Once your plants have gotten 4 sets of leaves you're ready to begin (sprouting leaves don't count). If your plant had a rough start or if you are a little unsure about clipping your plant when its so tiny, you can wait until node set 6 of leaves. If your plant is doing great and you are confident enough that you know what a sprouting node looks like earlier is better. Generally, your plant is going to be about 2 weeks old when you begin the initial training.

Snip off the growing tip of your plant between nodes 3 and 4 being careful not to damage the two growing tips above the 3rd set of leaves. You want 3 leaf sets below your initial clip.

When done topping your plant, you will have something that looks like the image above. Don't worry too much about time - if your plant takes a little longer to get to 4 nodes that's perfectly fine. Remember your veg time is not going to change, but you will need to work at the speed your plant grows NOT a given amount of time.
Allow your plant to grow as usual. Keep doing what you would normally do for a plant that is 2-3 weeks old. At or near the start of week 3 you are going to remove all the leaves below your initial topping with the exception of the two large fan leaves below your new growing tips. I believe Nebula suggests waiting until your new growing tips have at least 6 nodes before removing the leaves. I find that as long as your plant is healthy and has at least two nodes per each of your new branches that will work just fine.
When you are done with phase two of training your plant should look similar to the one below:

Generally, depending on your plant, phase two of training should be completed by week 3 or 4.
And... guess what? You're 80% done at this point, but the last 20% will kick your flower harvest into overdrive, I promise.
