  • 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.

    Fave dog toy!
    Color: Betty Bigfoot
    Great toy! My dog prefers the ball inside which is great for chewing on, bouncing, and playing fetch. Very thick rubber, lasts a good while. The outside cover is pretty tough, but for those who like a challenge it should last a little while. It really depends on how determined and fierce the dog is about chewing! We’ve had 3 of them. We always keep a back up for when one expires!!

    Perfect for Heavy Chewers—Huge Hit in Our House!
    Color: Aurora Beast
    This toy is an absolute favorite in my house! My dogs are usually pretty picky and can destroy most toys within minutes, but this one has seriously impressed me. It’s super durable while still being soft enough for them to carry around and cuddle with. They’re completely obsessed—whether they’re chewing on it, tossing it around, or just walking around proudly with it in their mouths. It keeps them entertained for a long time, which is a huge win. Definitely worth it if you have strong chewers and want something that actually lasts. I’ll be buying more from this line for sure!

    SUPERB FOR AGGRESSIVE CHEWERS
    Color: Betty Bigfoot
    Our Silver Lab, Theo, is a VERY aggressive chewer who loves destroying balls! We bought Barkbox Betty for Theo’s Birthday, and it was almost a week before Theo removed the cover when he discovered the ball inside and he loves it! And it’s tough design seems to be holding up! Eager to figure out if it floats! We will definitely buy this high quality toy again!

    Too hard and heavy.
    Color: Fowl Play
    Very cute idea but my dog was not at all interested. It’s too hard for her to chew on. She didn’t even care enough about it to rip the outside. It’s hard and heavy. I will stick with the non-super chewer bark toys. They don’t last as long, but she loves them.

    Tough & fun!
    Color: Betty Bigfoot
    This is my puppy’s favorite toy. I’ve bought 4 in case he eventually finds a way to destroy the ball because he is a 1 year old super-chewer. That said, this ball is TOUGH! It’s taken severe abuse from our dog & we couldn’t be more satisfied.
