Description
  • Cultiwool 4" x 4" x 4" Block (144 Blocks/Case)
  • 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.

    It really cools - Extremely soft - Not too heavy
    Size: Queen (90" * 90"), Color: Luxury Grey, Size: Queen (90" * 90"), Color: Luxury Grey
    This comforter arrived packaged very well from the manufacturer. It arrived sealed in plastic inside a box. The color and appearance of the comforter received looks like what was shown in the listing. This comforter is extremely soft. It feels very cool to the touch. It has a great cooling effect. It is also not too heavy. A lot of cooling bedding products like this feel heavy. While this does have some weight it is not too much. It is easy to move around. The comforter is easy to refresh and cool off again after extended use. I just uncovered myself, lifted and moved the comforter around a little, then covered back up. This made it feel cooler again. I am very happy with this comforter so far. I like the color and design. I really like feeling cool when falling asleep. This will be great when the temperatures start going up. I will update this review later if anything changes after washing a few more times and longer use. I think this will be a good comforter for most hot sleepers who like to cover up all year.

    Feels seriously amazing!
    Size: Twin(90“ * 67”), Color: Luxury Grey
    This is my second cooling comforter from this brand and this one is just as amazing as the first. It’s silky soft and makes a significant temperature difference. It’s like magic; you don’t need to do anything special to cool it before bed. If you do want extra coolness, you can place it in front of your AC or turn on your fan for a little bit before bed and It absorbs the extra coolness but either way it lasts all night. I use it with the cooling pillow, and the hot summer nights are no match. It’s easy to wash, really silky, smooth, and actually cool against the skin. It also somehow has a weighted blanket-like feel without being heavy. I standby this blanket so much that this is my second one, highly recommend!

    Super Soft, Lightweight, and Surprisingly Cozy
    This ended up being so much better than I expected. The first thing I noticed is how incredibly soft it is - it has that plush, velvety feel that makes you want to keep reaching for it all day. It’s lightweight but still warm, which I really like. It gives you that cozy, wrapped-up feeling without being heavy or overwhelming, so it works well for everyday use on the couch or even for sleeping. For reference, I’m 5’2” and it’s big enough to comfortably use as a full snuggle blanket. It also looks really nice draped over furniture. The texture adds a little dimension, and the clean, simple color gives it a polished look that doesn’t feel cheap. One thing to note is that it arrives compressed, but it fluffs up nicely once opened and feels much fuller after a little time. The only thing to keep in mind is that lighter colors will naturally show dirt more easily, so that’s something to be aware of with regular use. Overall, this has easily become my go-to daily throw - soft, comfortable, and much nicer than I expected for the price.

    luxury fleece throw blanket ribbed plush texture cozy aesthetic blanket
    This is one of those blankets that instantly makes a space feel more cozy and put together. The first thing that stands out is the texture. It has that plush, ribbed look that’s been really popular lately, very similar to those oversized lounge chairs and couches with the same soft, fluffy pattern. It looks especially good draped over furniture and adds a nice aesthetic touch instead of just being functional. It’s also genuinely soft and comfortable. The fleece has that “cloud-like” feel without being heavy or stiff, and it’s warm enough for everyday use without feeling overly thick. The size at 50 x 60 inches is great for lounging, whether you’re watching TV or just relaxing. I really appreciated how it was packaged. Instead of being secured with a bunch of plastic fasteners, it was simply wrapped with a ribbon, which made it easy to open and avoided the usual hassle of cutting out plastic tags. It also arrived vacuum sealed and had no odor at all, so it was ready to use right away. They even included a full-color instruction card, which was honestly a nice touch. It goes over care and even styling ideas, which adds to the overall presentation and makes it feel more polished. For the price, this feels like a great value. It looks good, feels good, and works well both as a functional blanket and as part of your home decor.

    Good value, packed nice and small for travel or gifting, fluffs up thick
    I ordered this throw - which, by the way, is OEKO-tex and CERTipur rated - because I don't have a white, fluffy throw in my otherwise cream and tan colored house. It arrived vacuum sealed and wrapped with a bow in a miniscule bag measuring 2" x 8" by 8". If you want to travel, say on a cruise ship or on a vacation for a week, and bring a comfort item, this is for you. It's so small that it won't take up hardly any room in your suitcase, but once you arrive at your destination, wow. It expands and fluffs up beautifully. It's super soft and really thick and comfy. It washes and dries very well. (On a cruise ship you could wash in the shower and wring, then hang to dry - it would probably dry overnight, or faster out on the balcony). I tried to get a close-up of the fluffiness but my camera wouldn't cooperate. At $15.99 it's competitively priced and comes with the added bonus of being vacuum sealed. Also has a instruction booklet for keeping the throw looking its best. Highly recommended.
