That is an option, and the cheaper way to go. The only problem is that it is time consuming. Adult morph females are fairly expensive too, especially if they are het simple recessive. Your best option is buying almost breedable females and a simple recessive male to breed to them. Females can breed around 1200+ grams, so you may want to look for ones that are near 800 or 1000 grams. Put some weight on them before next breeding season. Make sure the male is at least 700 grams by breeding season to be sure he will go for you. Just something to consider. Good luck.
