Hey Spain,
As I live in Texas, I have not had a reason yet to grow them indoors.
Dr. Craig Sheppard is the expert at raising them indoors in a continuous predictable fashion. You could try to contact him directly, however keep in mind that their entire business model (
www.phoenixworm.com) is based around growing them sterile and in captivity for the pet trade and zoos. They are the only vendor that I know off that is able to grow them in sufficient quantities year long and ship to their customers on a dependable and regular schedule. So I know for certain that it can be done... however I must tell you that Craig is a friend of my father and he has spent years of his academic career studying this amazing insect. Without Craig's contributions there probably would be no BioPod today.
Therefor Prota Culture has committed themselves primarily to promote Hermetia Illucens as a means to manage waste. We do not desire to grow grubs for zoo's and pet store. I applaud that Dr. Sheppard's labor has finally paid off for him and his wife.
At the same time, you are more then welcome to discuss any topics related to Hermetia Illucens. Eventually our growing community will find clever ways to utilize them in more and more commercial applications of which "Breeding in captivity" is an import part of its success. How else might we succeed in eliminating the food waste generated by a restaurant in winter time in a place like Boulder, Colorado or Fargo, North Dakota?
Personally, I think it's interesting to learn all about these creature. Please let us know how you succeed in growing them indoors in Spain. I can tell you it CAN be done. However, if you are really targeting the consumer pet industry. Please give Dr Sheppard a call first. I know that if you work something out with him, he can jump start your business in no time.
Sincerely,
Robert Olivier
