About what I said below. I said to pour a 100-150 ppm solution at the base of the plant but I also said NOT TO LET GA3 COME IN CONTACT WITH ROOTS. What I meant to say was to use a solution of Indole Acetic Acid at 100-150 ppm not ga3.
Again, GA3 contact with roots, rhizomes, and tubers is bad bad bad for all plants.
I refuse to participate in the in the recession.

Use caution with this if you care to experiment. GA3 retards root growth and will kill your tubers/rhizomes if it comes in contact with them. Do not use on amorphophallus unless its a variety that can grow a leaf and an inflorescence at the same time but dot expect much tuber growth as GA3 retards that also because is a form of a root.
I've been using plant growth hormones for years. If you want to noticeably increase tuber growth then wait until the tuber has formed a leaf and the leaf is fully open and established. Then pour a 100-150ppm solution at the base of the plant avoiding the leaf,a higher ppm is not better, it will cause the plant to do different things. Just do this one time during the season and apply high phosphate or bone meal fertilizer. Keep in a hot and humid shaded greenhouse for optimal results. Using this method, I made a 2lb konjac grow into a 7lb monster in one season. The next year it gave me a perfect flower of specimen quality. Which Ive posted pictures of here in the past.
This year Im doing this too all my tubers

Thanks Marc! I'm always glad to see your posts on Aroid l.

Dear Steve,
Yes gibberellic acid has been "intensively" used to induce the production of an inflorescence with aroid. See all the work of henny and collaborators.
I wanted to try but never have time, so please keep me informed.
Here is the list of some papers by Henny:
Henny, R. J. 1980. Gibberellic acid (GA3) induces flowering in Dieffenbachia maculata 'Perfection'. HortScience 15(5): 613. species.
Henny, R. J. 1981. Promotion of flowering in Spathiphyllum 'Mauna Loa' with Gibberellic Acid. HortScience 16(4): 554-555.
Henny, R. J. 1983. Stimulation of flowering in Aglaonema with gibberellic acid (GA3). Aroideana 6(3): 71-72.
Henny, R. J. 1983. Flowering of Aglaonema commutatum 'Treubii' following treatment with gibberellic acid. HortScience 18(3): 374.
Henny, R. J. and W. C. Fooshee. 1983. Flowering of Aglaonema with gibberellic acid (GA3). A follow-up report. Aroideana 6: 135-136.
Henny, R. J. and R. L. Hamilton. 1992. Flowering of Anthurium following treatment with gibberellic acid. HortScience 27(12): 1328.
Henny, R. J. 1999. Gibberellic acid-induced flowering of Syngonium podophyllum Schott 'White Butterfly'. HortScience 34(4): 676-677.
Best regards,
Marc
