How do I use PRO-MIX® HP®?

To use PRO-MIX® HP®, open the package, remove some PRO-MIX® product and place into a large tub or container. Lightly break up any clumps so that the PRO-MIX® is light and airy. Most growers prefer to add a small amount of water prior to filling containers. If you add water, add enough so that the PRO-MIX® product is slightly moist to the touch. Do not saturate. Fill flats, containers and/or pots, without compacting the PRO-MIX® in the container. Plant your seedlings, young plants, etc., then water in containers.

Incredible Comfortable
Size: Queen, Color: White
These Utopia queen sheets are extremely comfortable and have a soft, smooth feel that makes sleeping on them really enjoyable. The fabric feels lightweight but still cozy, and they fit the mattress well without slipping off or bunching up. They also wash easily and come out feeling fresh and soft, which makes them great for regular everyday use. Overall, they’re a very comfortable, reliable sheet set that makes the bed feel clean, soft, and inviting every night while still being easy to care for.

It’s cozy and fluffy without it being heavy or too warm.
Size: Queen, Color: White
I ordered this in the color white in the size queen and I have to say I do like it. My only worry was if it was going to be too warm and it is surprisingly very light and airy, but it still gives you that feeling of comfy, which is what I mainly wanted. Right now it is a little warmer throughout the night but every now and then where I live I tend to have to put another blanket on top of me when the weather drops at night, which is annoying however, with this, it provides enough warmth without it being so heavy on you. I have to say for the price I can’t complain.

Great product
Size: King, Color: White
I absolutely love this king-size bedding! The material feels incredibly soft and comfortable, making it perfect for a great night’s sleep. It fits my king bed perfectly with plenty of coverage, and it stays in place without bunching up. The quality is excellent—it feels durable, well-made, and has held up nicely after washing without or shrinking.

Soft and fluffy
Size: King, Color: White
Very fluffy! I’ve been searching for one like this for YEARS that can replicate that fluffy hotel style feeling. Great quality, it’s a cool white color. Very warm. It has the little bands on the edges for your duvet cover to attach to. Perfect fit.
