  • 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.

    Great design
    Size: 25in
    Ball is very durable yet soft. Whistles when you throw it and goes very far. Handle is ergonomic with a nice rubber grip. Both the launcher and ball glow green in the dark. My GSD loves it. She’s 75 lbs and the medium ball is fine.

    Husband and dogs highly approve.
    Size: 25in
    My husband wanted us to replace one from a different company that broke. It had to have a glow in the dark ball, since he sometimes plays fetch with the dogs at night. He couldn’t love this more. Says it’s so much better than the other one, the whole thing glows in the dark and it throws farther. According to him, it’s the best ever.

    Glow In The Dark Ball
    Size: 18in
    I gave this 4/5 stars because the ball is a little small for my dog size so I was hoping the sizing was easier to read. It could have been an error on my end. The ball is great though! It lights up nicely when it is out in the sunlight or under a light for a long periods of time, it lights up at night so you can play with your dog at night when it is cooler!

    Well designed, well built.
    Size: 25in
    The stick facilitates powerful, long distance throws. The ball makes a light whistling noise (to help your dog track the ball) through the air, flys far, and has held up well. I live in an area with mountain lions, and they often hunt at night, so I haven’t taken advantage of the glow-in-the-dark feature.
