AA+ spores are a type of spore that can be used to cultivate magic mushrooms. These spores come from the Psilocybe cubensis mushroom strain known as "Albino A+" or "AA+" for short. This strain is known for its large, dense fruiting bodies and high potency.

AA+ spores are usually sold in syringes or spore prints and can be used to inoculate substrates like grain or agar to start the process of growing magic mushrooms. When the spores are introduced to the substrate, they germinate and grow into mycelium, which is a network of thread-like structures that eventually give rise to the fruiting bodies that contain the psychoactive compounds.

One benefit of using AA+ spores is that they are relatively easy to work with and can produce a good yield of potent mushrooms when grown under the right conditions. However, like any type of spore, there is always some degree of variability in the resulting fruiting bodies, so it's important to have a reliable source of spores and to follow proper cultivation techniques. 

It's also worth noting that growing magic mushrooms is illegal in many parts of the world, so it's important to research the laws in your area and proceed with caution if you decide to undertake this process.
