Veterinary vitamin complex for orchids...???

[Georg Luiz Barth]

Hi guys, a few orchidists here in Brazil are using a veterinary vitamin complex called Vita Gold. Spray 10 drops of the product on the leaves and roots, diluted in 1 liter of water, once a month. "They say" it's great for getting orchids to root quickly. I believe it is one of those speculations, without scientific basis....but I would like your opinion.
