Grape Ape is a hugely popular indica strain. Grape Ape will relax you and keep you sleeping all night. Grape Ape is most effective in treating chronic pain, such as migraines and arthritis, but it can also help with anxiety, sadness, and PTSD. Because it has a near-comatose effect, this is a nighttime strain. On the other hand, the high can be euphoric and focused with a clear mind.
