Selam Anıl,
ooohhhh...
Conophytum!! I have managed to KILL all my
Conophyta! 
Loam absolutely doesn´t agree with
Conophytum! I consider
Conophytum to be even more difficult then
Lithops. It seems they prefer a little organic material in the soil mix such as peat. Maybe 20 or 30%. They also seem to like coarse quartz sand (2mm grain). I haven´t had success with pumice either. But I am used to the fact everything´s strange with me.
In Germany many people swear on growing
Lithops and
Conophytum in pure pumice. Some add lava rock pieces. But these people grow these plants all in a greenhouse or outside. Pumice doesn´t work for me as it saves too much moisture deeper in the pot. Which often causes root rot on my
Lithops.
Conophytum is a winter growing genus in opposite to
Lithops. So,
Conophytum likes water in winter and prefer dry summers. However according to Rafael Matysiuk (assistant of Cono´s Paradise)
Conophytum don´t stand longer terms of total dryness. *shrug* I don´t know. For some time I won´t try
Conophytum again. Though there are some species I really love such as
C. pellucidum "terricolor",
C. burgeri,
C. stephanii and
C. minimum "wittebergense". Maybe in two years I´ll try them again.
Will9 is
the man here at CPUK who originates of growing cacti and succulents and to give you good advice on growing
Conophytum and other Mesembs. You can drop him a pm if you want to.
I have got the tip to spray grain alcohol (
Spiritus in German) on spider mites and it worked in winter. This summer I have KILLED hundreds of
Lithops, Faucaria und
Conophytum through spraying grain alcohol on them to eradicate the f****** mites! To make the story short: My
Lithops, Conos and
Faucaria have literally died through extreme
drunkness!!!!

So, my most urgent advice is:
Keep your fingers off alcohol to treat pests!
I have three different agents I can use against spider mites:
Kiron (which is only a contact agent and has to be used repeatedly within 8 days),
Kanemite (which is systemic, but only after two weeks the mites were there again!

) and finally
Provado which is not a special acaricide like the other two but helps well against spider mites. This year spider mites seem to be
omnipresent on my Mesembs!

Which forces you to permanently apply pesticides.
Vertimec is another very good control against mites but extremely expensive as it´s only manufactured for professionals.
Maybe - I don´t know - oil containing agents also work against mites such as
Raptol? I have no clue which agents are available in Turkey.
Not long ago (after my disaster) I was recommended to use
BIO KILL against spider mites. It is also based on
pyrethrines like
Raptol but without oil. So, I will soon purchase
Bio Kill as the fourth agent against mites...*sigh*
Also I was recommended to mist my plants twice daily - just very slightly of course! But that may chase away spider mites as they usually dislike moisture and humidity.
I have completely renewed my
Lithops collection and so far no new spider mites have appeared again.
Lithops do have made me
addicted to them!!!

But I have repeatedly problems in growing them. It goes well for half a year or so and I think I master
Lithops. But then suddenly problems occur.
I guess Dr. Hübner grows her Ascleps inside a greenhouse and there waterings are more often required. The soils don´t dry out so fast under my conditions.

It doesn't stink like Orbea but it's like...protein...if you know what I mean
I was told the flowers of
Huernia and
Orbea don´t smell much noticeably for humans but
Stapelias shall be terrible. I hope they are right...I....errr...sleep where these plants grow!
Looking forward to see your
Caralluma rogersii flowers. :-)
Sevgiler,
