Terrarium Substrates | Soil & Growing Media for Terrariums

Quality substrate lets terrarium plants establish strong roots, hold the right amount of moisture and access nutrients. Our terrarium substrates come in smaller bag sizes ideal for compact containers, so there's less waste and it's easy to build layers with drainage, activated carbon and planting media. They drain well to prevent waterlogging and root rot while keeping the steady moisture tropical plants need. Use them for new terrariums, refreshing existing setups, or separate planting zones for different plant types.
