I finally caught up on this thread.
Are you folks talking about changing ploidy through the use of colcichine (yea, I mis-spelled it too). Orchid growers use this to change diploids into tetraploids. I've seen the results on multi-floral Paphiopedilums. It only works on about 20 percent of the seedlings, but Wow!. The growth is thicker and larger, and so are the flowers. Unfortunately, tetraploids tend to grow a bit slower too.
Have to agree with Josh 100 percent on the Growmore fertilizer. We've experimented extensively with different fertilizers on Nepenthes, as well as techniques of application, and have settled on the GrowMore formulation. We use the high nitrogen formula, not the bloom bloost. Michelle(my lovely and charming wife who is quite the Nep grower) has demonstrated to me consistently the positive attributes of GrowMore and her fertilizer schedule which really works. This info will soon be available on our website (that's why I never post pictures-want it to be a surprise).
We've also used SuperThrive, and found it most effective in treating seedlings suffering transplant shock. Superthrive is vitamins, not fertilizer, and thus does not substitute for fertilizer. Plants need those essential elements (see Josh's post), but they must be applied in a manner they can be absorbed and metabolized.
