Thank you, Ray, for your advice and I will check out KelpMax. And thanks to you, STXorchids 35, for your advice also. I guess I'm on the right track because my Vanda is hanging bareroot and it gets a mild fertilizer in rainwater everytime it is misted which is several times a day and soaked in the same for an hour once a week. I think I will apply a liquid rooting hormone by brush to every dormant node along the bare stem. Thanks again to both of you!
