I currently have my Phal in Sphag moss. I was wondering, from your own personal experience, what is the best potting medium/substrate used to grow Orchids in?
Ive heard Sphag holds water better and longer, Orchid/fur bark stays humid for almost the same time and is almost the same as Sphag, and Lava rock I would assume is good b/c its porosity can also contain pure water that can feed the orchid roots for quite some time.
My question is, from your experience, what do the Orchid roots like more? Do they like sitting in Sphag, clinging to Bark, or clinging to the lava rock?
What do you all have the most success using??
I know that different species of orchid have different requirements, so for the sake of argument, please lets stay focussed on Phals.
Thanks!!
p.s. I would think there is more risk of root rot using sphag and bark, than with Lava rock??
