Gordan Delta Gro-Slabs provide the final stage for growing a spectacularly large plant. Transplant your Gro-Block plant onto a slab just like professional growers. They come in clearly marked biodegradable UV resistant sleeves for comfortable handling and algae prevention.

Water and nutrient distribution is also more uniform and provides a larger effective rooting volume than previously possible.

Grodan slabs come in four sizes.

The 6in wide slab is suitable for crops such as tomato, pepper and eggplant.

The 8in wide slab is used for more water hungry crops such as cucumbers.

Standard cut flower slabs are designed for multi season use. They have a uniform, high fiber quality and excellent structural stability.

The 4in high, 6in wide slabs are suitable for production of all types of cut flowers such as roses and carnations.

For stock plant production of poinsettias, mum etc., consider the 12in slab.
