Jack in the Bud-
What I've done in the past is top the plants at 5-6 nodes, above the 2nd node, for 4 colas, just as the first page describes. It took approximately 2.5 weeks for the plants to get to that point. I continued vegetative growth for another 1.5 weeks, leaving me with plants that were roughly 7 inches tall. After flowering, my indica dominants stopped growing at just under 2 ft tall.
The small plants contain an enormous amount of bud though. Although I'm having problems getting 4 identical colas, all the plants have 2 stocky heavyweights that are truly admirable. One of the 4 plants will be easily yielding me 2 ounces. For a newbie working with CFLs, that is more than I hoped for.
If space is an issue, I have to think this method will work better than you could ever dream.
