In the interest of conservation of CP in their natural state and their 
dwindling habitat, an unsolicited tip:
It's a good idea to check out the dealer(s) from whom you buy CP... Is 
the stock of the spp. you purchase propagated (at least 2nd/3rd/etc. 
generation from field collected)?  Are ALL the species sold by that 
dealer propagated?  What is the dealer's overall attitude about field 
collection?
Hint:  check out books which have been written about the subject, e.g. 
the INTRODUCTION ;)!!, by the owner/operator of the enterprise if they are 
available, etc.... to find out whether you agree with their philosophies...
Get my drift?
Happy growing  :)!
