Product Information




Stonewool is recognized the world over as a dependable hydroponics growing medium and Grodan stonewool in particular is known for its quality, consistency and performance. Once plants develop a healthy root system in the smaller stonewool plugs and blocks, they are transferred onto one of these larger Delta Slabs for the remainder of their growing cycle. This single Delta Slab is wrapped in a biodegradeable, UV-resistant sleeve for easy handling and algae prevention.

The final stage of planting is the Grodan Delta slabs. There are three slab types available in a variety of sizes.These slabs come in clearly marked biodegradable UV resistant poly sleeves.

The poly sleeves have several functions;
- Comfort in handling.
- Preventing algae growth.
- Preventing roots and diseases from moving easily from slab to slab.
- Minimizing evaporation.
- Enabling full saturation of the slabs before use.
- Controlling/directing the water-run off from the slabs.
