  • 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.

    Stable and attractive
    Item Package Quantity: 1, Color: Black
    Love the black, it matches my kitchen well. Very sturdy, more so than the Simple Human one that the tension arm broke. A very good product.

    Great paper towel holder
    Item Package Quantity: 1, Color: Black
    This paper towel holder works well for holding the roll while you pull off single sheets. It's heavy and sturdy.

    Passed (my) test: 4/5
    Item Package Quantity: 1, Color: Black
    I used to have a paper holder affixed to the wall. Obviously, it was stable but not always delivering the size of paper towel that we expected. After redoing my kitchen backsplash that I didn’t want to pierce through just yet, i decided to go for an countertop paper towel holder, and i picked this one (in black) Reviews were decent and i liked that it has an “arm” to hold the paper. So, i put it to the test (see video) Here are my conclusions: 1) Solid built and weighted at the bottom + rubber to prevent the holder from moving around while pulling the paper 👍🏼 2) out of five trials at pulling the paper, i only had one fail (see video) which is still a better ratio than with my wall holder. 👍🏼 3) There are probably cheaper holders on the market, but most of them are not stable and require two hands to pull paper. This one is easy of use with only one hand which is useful while cooking. 4) i like that this holder comes in different colors, to match the kitchen decoration. 5) The hook at the top of the holder is convenient to carry the holder out of the kitchen, to the dining table for example.

    Great Product - Exactly what I was looking for
    Item Package Quantity: 1, Color: Black
    Great product. Love the black color and the look on my counter. The tension arm does its job and the product is stable when taking a paper towel off the roll.
