Wow Uri! Great petals! I love it! I think my bohlmannianum that I just won off of the raffle table for $1 is in possible low low spike! Uri, do you grow yours cooler? The colors look very nice and strong! Well done!
I have 2. One clone produces growths frequently, and when kept in a basic mix would add and loose roots frequently. The other clone grows bigger, but divides much less frequently, and always seems sparse on roots when in a basic mix.
Given that they can be found in both acid and basic mixes I switched to a standard bark mix, cooler temps, and less light about a month ago, and they seem to be improving.
