Wood Fiber. Brick Shards. Polystyrene Packing Peanuts. Vermiculite. Although growing hydroponically is soil-free, this doesn’t mean that there is nothing to support our plants.

Many hydroponic growers use perlite as their primary medium (especially if they’re growing in Bato or Dutch buckets). That said, there are both pros and cons to using perlite in hydroponics. Growers should choose a medium based on how much it weighs, how easy it is to handle, how it impacts system pH and diseases, the size or texture, etc.
Hydroponics is a system of container gardening in which plants are grown without soil. One of the most common types of hydroponic systems, an aggregate system, supports the roots in a soilless potting medium such as perlite or peat moss. Cover seedlings with ¼ inch of peat moss.
