Re: [Aroid-l] gGbberellic acid and inflorescence production

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
