Nicki, Acclimation is a process, but I do not think it is a science. You will probably be improving the light conditions. Look out for sunburn.
I would suggest you buy a plant in bud and bloom so you can be sure you like what you are getting. The buds should not be brown or dry (blasted) and the blossoms should be fresh, not spotted. Look at the leaves and check for infestation (usually scale or mealybug, sometimes fungal spots). Make sure the plant has not been over-watered. The roots should be firm, not mushy or dried to death. Having the name tag is a real plus and it is not the same as a care tag. Joe
