The whole concept of BitBean seems pretty new and interesting. However, I've a few questions to ask before I start sprouting.

Does the sprouting takes heavy usage of CPU or GPU (or just the network usage)? What if I sprout with my GPU rig while it's mining something else? And according to SproutingCalculator, it's recommended to have 100,000 beans, can I just start with 15 to 20,000?
