  • Cultiwool 3" x 3" x 3" Block (400 Blocks/Case)

  • Cultiwool 3" x 3" x 3" Block (400 Blocks/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.

    Perfect for your sink organization
    Color: Silver Grey
    I have searched many sites for a product that will fit on our sink for all our kitchen and dishwashing needs and I finally found this product which proper fits with our kitchen decor and fits perfectly on our sink and it is very strong. I’m not worried about it breaking it anyway. Well with the price.

    Love it
    Color: Mattle Black
    We'd been looking for a sponge holder we liked for a while andy wife came across this one. We were not disappointed. It's plenty big to hold a handful of sponges and scrubbers, plus our hand soap. I like the design that lets excess water drip back into the sink. Looks pretty low profile and sleek too

    Keeps the water off your counter!
    Color: Mattle Black, Color: Mattle Black
    Works great! I’ve been looking for a solution to stop the sponge water from spilling onto the counter! Liked nice and neat. Great for keeping everything neat and organized. Size is perfect for sponges and nail brush and a small soap bottle.

    Works great for my space
    This is the perfect size for my sink area and holds what. Need it to hold. Love the little drain tray, as it helps to dry what is in it and allows my counter to stay dry
