I have been growing peyote from seed for about 16 years now, so have acquired some experience.
Huxley needs to be buried a little deeper in a gritty, well draining soil mix with some lime - the line on him between green and brown shows you just where he would like it. And I put
Lophophora and other cacti with a deep taproot in Long Tom pots - which are deep relative to their diameter.
He is a very bright green, peyote are naturally a blueish grey - more daylight will do that for him.
I have never known a peyote on its own roots produce offsets until after it has flowered - they flower for me after 2 years, and may produce offsets after about 4 or 5. But not all
L. williamsii do produce offsets - here one has them in profusion and one just plain hasn´t.
In fact the one on the left is the offspring of the one on the right, so the tendency would appear to be not necessarily hereditary.
Peyote are not as fast growing as, say, Astrophytums, but there are many globular cacti in my collection that are a lot slower. Good luck with Huxley.
Life is a shit sandwich - the more bread you got, the less shit you eat.
