Hello all,

Hope you are doing well,

After my unfortunate mishap with my phal about a month ago.

I unpotted that flower last Sunday and found out that the roots were almost dead, only had 2 good roots left, So i decided to experiment and I cleaned the flower, cut off all the roots and placed in a water culture, hoping it will live again.

I don't know why that happened, the Phal seemed to be doing really well especially since it was placed in S/H for more than a year.

However, as my good friend "Halloamey" advised me to acquire new orchids and keep growing.
I purchased two new Phals and an Oncidium (I think? correct me if I'm wrong.)

When I purchased the Phals, I focused on the roots health, number of roots, number of leaves and health of the stem. At the end I looked for flower colors that I don't already have.







I am a bit worried about this Phal's leaf, please advise.



As for the Oncidium? the flower had already lost it's flowers, the flower shoot is all dried up and brown; and I purchased it for a fraction of its price, The bulbs looked healthy green and pulp.





My question is the following:

I want to repot the new acquired Orchids into S/H using hydroton.
Is it OK if I repot them now while they are still flowering? The current medium is a bark mix and I am not comfortable with it, because they are still in their shipping pots!
What about the areal roots, should I force them into the hydroton medium or keep them outside as they are now in the bark mix?
Can the Oncidium be placed in S/H hydroton medium? If yes should I place the bulbs above the Hydroton pellets? (is there a pictorial thread of an oncidium being repotted into a S/H medium?)
Does the size of the S/H pot matter for both the Phals and the Oncidium?

Looking forward to reading all your replies and advices.

Thank you all in advance.
