Yes, growing garlic indoors is possible. However, you may not be able to produce a head of garlic with the same quality as you would if you were to plant garlic cloves in the garden. Instead, you will be able to produce garlic sprouts or greens. This is not to be mistaken for early spring garlic grown from immature garlic bulbs. Nonetheless, the garlic sprouts are just as tasty as spring garlic, but lighter in flavor and have less of a pungent taste.
