Hi, Wood ...
The idea in SOG is to grow a LOT of little, single cola plants in one area. By a lot, I mean four per square feet of growing space. To do this, you'll need to grow a strain that makes sense. It will have to be very Indica-like. Short and bushy. The flowering cycle should be started when the plant is very small, like under six inches. Then, you'll have to prune the plant into that one cola shape. The end goal is to end up with tons of single cola plants that produce between 1/4 and 1/2 ounce each.
The bad part is, with the huge plant numbers, your security is compromised. Remember ... the feds get real snotty when the plant numbers exceed 100. Its real hard to convince anyone that with those kinds of plant numbers that your grow is for personal use as well.
For the record, one of the most successful SOG growers I've ever seen uses Legend's "Ultimate Indica" in his SOG grow. The guy is amazing.
