Again, just for clarity, if I said somewhere that each cut doubles the yield, I misspoke. The only time that is even remotely true the very first cut you make... you turn 1 into 2. When those nodes come up and you top them again, 2 becomes 4, another doubling. Even if you stop cutting here, by this time 2 more have risen up from node 3, that would not have risen up to the top without this training. 4 becomes 6. If things are going right, those rising from node 2 are now approaching the canopy. 6 becomes 8, finally redoubling the second doubling.
More chopping can be done from this point to further increase the number of buds, and it's not crazy to see how an Edward Scissorhands type gardner could quickly increase the bud numbers to 16, 32, and I have seen plants with over 50 buds on them by using this exponential topping method that I like to call the Whack-A-Mole method of training.
Given enough time, a plant of this size could double its yield up to 6 times, producing a massive plant. Given enough soil, water, nutrient and time, this could happen... of course limited by how much you can get into the plant, including every input, air, water, space for the roots, and time you wish to stay in Veg. The natural thought is to believe that the plant could never supply the same sort of quality or size to each of these buds, logically creating substandard quality at best. I have seen credible arguments that there is no way that these buds could approach the quality of a plant that has been left alone to produce only one main cola. There are too many factors here... I am not certain that this is necessarily true.
But, give the limitations of indoor growing, our own capabilities, the time involved, it is reasonable to say that a smaller well run plant, not going crazy with extra buds, will more easily be able to get everything that it needs to produce superior buds. Also, in the 100-120 days that it takes to veg a massive multi topped plant, you could grow two seasons of a smaller less producing plants, getting close to the same yield in the same amount of time. So in that sense, I totally agree with you
@Azimuth. The increase you get in topping is incremental and not always worth it. In the last recent experiment that I did using the Whack-A-Mole topping method, ending up with multiple plants with 30 or more buds, I realized that it would have been a whole lot more efficient go with fewer buds better airflow and quicker turnaround. The LSD plants now in my bloom room ended their training at the 6 becomes 8 stage, doubling three times. This produces a very efficient plant with minimal stretch and with proper management, I believe, a plant capable of producing 3x what a single cola plant could do. At least, I think that I have given them the capability of producing a whole lot more than they would have naturally, without going crazy with the topping, and I am now convinced that going much further than this in the training is actually sort of mad.
