soilless

Grown in water

Soilless describes methods of growing plants without traditional dirt or earth, using instead materials like water, gravel, perlite, or coconut fiber combined with nutrient solutions.

Hydroponic and aeroponic systems are the most common soilless approaches.

The rooftop greenhouse uses soilless cultivation to reduce weight and mess.

Soilless mixes for container gardening typically combine peat moss, vermiculite, and other lightweight materials that drain well and resist compaction.
