Oyster mushrooms are the easiest and most satisfying to grow. They grow in clusters, are quite meaty, and can grow quite large depending on the environment although taste better at a mid-size.
The easiest way to grow them is with a ready to fruit mushroom kit. An oyster mushroom kit can have between 4-8 harvests each block, yielding from 300-700 grams per harvest. The first harvests yielding the most and then less each time as the mushrooms break down the block (which is its food source).
