Receipt for roots

[IvoPhal]

recently received a few paphs from eBay with weak roots. I’m looking for guidance how to rescue them. The are niveum, collosom, Argus anyway small plants in poor condition. I found here in this wonderful forum some ideas with sphagnum moss , pumice and small bark.
The ratio is that I did not have information.
The stash from my bonsai’s is : pumice, Akadama Kiriy and small size bark for seedlings, bigger one like classic orchiata and all kind of substrates…..The plants are currently repotted in classic orchiata and pumice 50:50.
I’m in flat central heating , lights for orchid , cheapest one, humidity 50-60.
All advice are appreciated….

Do you have access to a seaweed based rooting stimulant like Kelpak? That has been a game changer for me!

Yes and no, unfortunately the shipping was terrible they destroyed the bottle of Kelpak and this weeke I’m expecting new one.
I have other seaweed-form growth the technology “ orchid plus” , velokelp etc.
I” still looking for the substrate that suits me, 8 it’s humid around here 60-70 and the summer time is like in desert 30
So I have idea of repotting plants with “summer” medium and “winter” ones, 6 months each.
