Coelogyne velutina

[Spider]

I have a young plant of this Coelogyne. It is warm growing, and it is growing. It has 2 new bulbs now, in a very little pot, so it has to be repotted. But I have to wait until the last bulb has grown tall and getting new rots. I´m intending to plant in pure Spagnum in a hanging basket lined with a cocosfiber mat. Ihave wondered a bit about the feeding. As spagnum likes an organic feed, I wonder how this should be done as I`m using RO-water.
