Re: [SANS] Leaf cutting

I have never kept records, but have a fairly good  notion. the slow growing
ones like the one from Eil Pas, take very long, and the faster ones like
the hahnii types are very much faster. but when i do such things i use the
intense propagation greenhouse where everything is designed to speed up
metabolism. soil temp is about 80 degrees, lots of diffused light,
humidity, long daylite hours...the works. because some of them can root and
take forever, meanwhile growing a monster piece of callus tissue.  pulchra
has done that often. a short while ago John "near the biggest crisps
factory" said he was still waiting for his arborescens...after some
incredible length of time. Juan indicated he thought light intensity had
something to do with it. in the prop greenhouse it gets blindingly bright,
but the humidity keeps the plants from dehydrating and the day temps can go
over 100 degrees F. this is where we germinate palm and cycad seed, root
our difficult cuttings and even start our bamboo. it is a real "stove
house". and yes, the Sansevierias take to it quite well.
