Sorry if this has been discussed...I didn't read all the other posts...how much light are you giving this guy? I don't grow it any more but when I did, it was in the high end of catt light. It bloomed very well and without fail each year. It smelled awful but it was beautiful.
You grew a bulbo in high light?? Is that the key to echinolabiums blooms? May i ask if you did anything else?
