This manual is designed to give basic information that has been shown to be successful in a variety of situations. We have often opted to describe methods that may be too sophisticated or expensive to apply in every case in an effort to illustrate the optimal condition.  Obviously, not everyone will be able to install stainless steel caging and automatic watering systems, but to omit these would impede individuals aspiring to achieve the ideal.  In most cases we must rely on your ingenuity and creativity to 'make do' for your particular climate and cost restraints.
