I have these noid mini-cymbbidium leafless bulbs which looks like they are gradually dwindling, but lately I have seen some new growth, though the bulb itself looks utterly dry. I have repotted them in pure hydroton, coz I am confused whether it will come back or not...my question is, with this scenario, should I water more frequently or just water it once every 10 days? The hydroton media does dry quickly.
