The most popular slab for growers due to its value and proven reliability. The vertical structure of the fibres helps promote the rapid initiation of vegetative growth at the beginning of cultivation.

Because of the structure of the slabs the water retention, absorption and air movement is excellent giving your young plants the push they need to develop faster.

Each slab measures 550 x 370 x 150 and fit perfectly into a 45l tub
