  • Cultiwool 6" x 6" x 6" Block w/ Optidrain (48 Block/Case)

  • Cultiwool 6" x 6" x 6" Block w/ Optidrain (48 Block/Case): Cultiwools' growing blocks are unique in the most efficient way. That has everything to do with the consistency of the products. Quick and easy uptake of water and the homogeneous distribution of water throughout the substrate are one of the most important features of a growing medium. Not only can you expect the highest quality stone wool in the market, but Cultiwool is also the first to introduce the 'donut ring' for the retail market to even further improve water distribution. This is in addition to the highly appreciated cross grooves to improve water flow under the block, and the black/white foil to prevent algae growth. The Cultiwool substrate blocks are provided with drain grooves at the bottom to improve the waterflow under the block. This is especially useful when the substrate blocks are placed on cultivation tables and concrete floors. Another benefit of the drain grooves under the block is that it will limit the contact surface with the ground. This will avoid bringing deseases in to the plant through weak roots often in combination with too high temperatures. As first in the industry, Cultiwool will provide the substrate with a donut ring as well, a water chamber around the plug hole to place your drippers. With the donut ring you will achieve an even more homogeneous distribution of the water throughout the block. A welcome second advantage is that you can not make any mistake anymore with the positioning of the drippers in the block.

    Good content, very small print and photos
    Format: Paperback
    Get a magnifying glass… the print is tiny. They must have made this book to be a large hard cover because both the print and the photos are so small in paperback. Content looks decent. It’s a gift for my grandson who will probably spend more time with the photos than the reading anyway and his eyesight is better than mine. :D
