  • Cultiwool 4" x 4" x 2.5" Block (216 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.

    Color: Frosted Lavender, Size: Twin, Color: Frosted Lavender, Size: Twin
    I really like these sheets. They are soft, lightweight, and fit my twin mattress perfectly. The lavender color looks beautiful in person and they feel comfortable to sleep on. After washing, they still looked nice and didn’t wrinkle much. Great quality for the price!

    Bed Sheets
    Color: Bright White Striped, Size: Queen
    I’m really happy with these bed sheets. They feel soft and comfortable against the skin, and the crisp white color gives the bed a clean, fresh look. The fabric is lightweight but still feels durable and well made. They fit the mattress nicely and stay in place throughout the night. After washing, they came out looking great with no noticeable shrinking or loss of softness.

    Great sheet set
    Color: Blush Pink, Size: Full
    Super soft right out of the package. Thin material but should be perfect for cool nights. Blush pink is the perfect shade of pink. Love this set. Highly recommended especially at this price point.

    Perfect Lightweight Sheets for Sensitive Hot sleepers
    Color: Cream, Size: Queen
    These sheets are soft, thin, and absolutely perfect for me. I have advanced CRPS and erythromelalgia, so I deal with severe nerve burning and heat sensitivity and cannot tolerate being overheated at all. I keep our AC between 56–64 degrees constantly, and since our studio is small, it usually stays around 61–63. These sheets have been a lifesaver for sleep. They are lightweight, breathable, and don’t trap heat, which helps me avoid extreme flare-ups and the intense burning pain I deal with. I'm bedridden so I need to be comfortable. They feel comfortable against my skin and don’t worsen my symptoms when I’m already in a lot of pain and look nice, wash nicely. For the price, they are also a great value. I’m genuinely grateful to have found something that helps me rest more comfortably. Will be buying more for us and gifts.
