C. walkeriana flower bud!

Two new growths appeared on my C. walkeriana. I think the one on the leading pseudobulb is (most likely) an inflorescence, as it is more rounder and terminates with reddish sheath-like growth; and the one coming out of the back bulb is just a new pseudobulb, as you can see there is a green leaf tip emerging from the growth (it is also quite flat). It is interesting to see the difference between these two growths.

BTW, mine is growing on a pseudo-semihydro-mount-ish thingy I have built from a rolled up plastic gutter guard lined with fiber clothes (actually, chopped up dish washing scrub pad) and chunks of pumice, which is sitting inside a reservoir filled with gravel and water. So far, it worked quite nicely and all of my walkerianas are now being grown like this.

I'm not too sure. Wait till someone who grows walkeriana can comment - to me both growths look too similar to be different from each other.
Leaves can be green or purple, and they both look like leaves to me ..

I'm curious to see how that other one progresses. I generally see either inflorescences or new growths happening at any given time, not both simultaneously. Certainly could happen, just not super common! Spikes on walkeriana & nobilior are usually more pointed than new growths.

It is indeed an inflorescence. :)

Two buds are emerging from the growth.

And this is the lower growth, which is just a new bulb.

And it is currently sending out new roots.

Ha! Very cool!

Very pretty! Mine has a very ugly growth and the leaves are wrinkled at the beginning, it is very small but it blooms a lot.

Really cool method of growing! I really want to try your method of growing walkeriana! I've seen some Brazilian growers use something similar but they fill the cylinder with granite chips. your wicking method might be an upgrade. also a huge space saver because I have one walkeriana that grew 4" horizontally this year

Could you share a picture of the actual setup from a bit more far away?

Actually, it was the third image I attached at my second post, but forgot to include into the post as a tag.

Walkeriana grows very well mounted
