Description

  • Cultiwool 4″ x 4″ x 2.5″ Block (216 Blocks/Case) – Cultilene: Cultiwool’s growing blocks are known for their remarkable efficiency. Their superiority is linked to the consistent nature of our products. The swift and uncomplicated absorption of water and the even distribution of water throughout the substrate are prominent features of a competent growing medium.
  • High Quality Stone Wool: Alongside offering the finest quality stone wool available in the market, Cultiwool also pioneers the introduction of the ‘donut ring’ to the retail market enhancing water distribution. This additional feature is coupled with the highly valued cross-grooves which augment water flow beneath the block. Moreover, it includes a black/white foil to counteract algae growth.
  • Cultiwool Substrate Blocks: Our blocks are designed with drainage grooves at the bottom to optimize the flow of water beneath the block. This feature is particularly beneficial when the substrate blocks are positioned on cultivation tables and concrete floors. An added advantage of the drainage grooves beneath the block is that it minimizes the contact surface with the ground, thereby preventing the introduction of diseases into the plant via weak roots often associated with high temperatures.
  • First in the Industry: Cultiwool stands as the first in the industry to equip the substrate with a ‘donut ring’. This is a water chamber around the plug hole for your drippers. With the donut ring, you will attain an even more uniform distribution of water throughout the block. An additional bonus is that the donut ring eliminates any chance of errors regarding the placement of the drippers in the block.
  • Cultiwool 4″ x 4″ x 2.5″ Rockwool Blocks: These superior blocks are sold by the case, ensuring you have the necessary quantity for your needs.
