  • Cultiwool 4" x 4" x 4" Block (144 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.

    Terrifying jaw strength..
    Color: Green, Size: Medium(30-55 lbs)
    Have 2 Corgi and it scares me that they make this thing squeak. The bite pressure they have now from working out jaw to squeak this like it's nothing. Didn't expect our smaller corgi to be able to squeak this couldn't at first now she just goes ham on it like it's no big deal.

    Very sturdy for an aggressive chewer
    Color: Green, Size: Large(50-90 lbs)
    I was so surprised that this has lasted so long for my Black lab, who is an aggressive chewer. It is his all-time favorite toy. He chews it many times every day and the squeaker still works!

    I FINALLY GOT AN INDESTRUCTIBLE TOY!!! Yes!
    Color: Green, Size: Large(50-90 lbs), Color: Green, Size: Large(50-90 lbs)
    This one is TRULY indestructible! I’ve been purchasing one after another trying to find something that she cannot break in 5 mins. Everything I’ve ordered (until this one) has been SHREDDED in 3-10 minutes! It’s TRUE RUBBER! I’m so happy with my purchase! See the picture below- we’ve had it for a couple months now and she has barely chewed off just a few small nubs! Which she’s proud of 😆 If you truly want a challenge for your CRAZY DOG- you will love this squeaker!

    Rough and tough chew toy
    Color: Azure, Size: Large(50-90 lbs)
    This is a thick and heavy duty toy to stand up to medium to large dogs who are heavy chewers. And the rough textures really encourages my dog and it is the perfect size to throw and play fetch. Very sturdy…I bought around Christmas and it’s almost may and she hasn’t destroyed it yet!!!

    Very sturdy and strong toy
    Color: Green, Size: Large(50-90 lbs)
    This keeps my dog busy. He has a blast with it. It is a little bit big for his mouth, but he still seems to have fun with it. My dog is German Shepherd and Australian Shepherd.
