Securely Attaches to Driftwood --- SunGrow Cotton string securely ties plants to driftwood and rocks in your tank or aquarium. At a length of 65 feet (20 meters), the green thread can be cut into smaller pieces to suit your specific needs. Leaving No Trace in a Matter of Days --- After tying the thread securely to a rock or piece of driftwood and dropping it to the bottom of your tank, it will (over time) completely break up leaving no trace that it was ever there. By the time the cotton thread disintegrates, the plant is anchored down and won’t float away. Green Color Blends into its Background --- In a rich, green color, the inconspicuous cotton plant string from SunGrow blends in flawlessly with your beautiful underwater habitat. The green thread color matches you to recreate a realistic enclosure. Meant For Both Aquatic Plants & Pets --- Our product is made using cotton thread. Commonly used to tie down plants such as Willow, Java plants and more, the plant string can be placed in shrimp tanks, community fish aquariums, and water terrariums. A Variety of Other Creative Uses --- Along with filling your aquarium or plant tank with incredible greenery, there are a few other ways to creatively use our cotton thread. You may secure young vines to trellis to a unique, artistic pattern. It can also be used as a string to hold helium balloons. How does Moss Cotton Thread work? Our green cotton string is used to tie down floating plants such as java fern, willow plant, duckweed, hornwort and more. These types of aquatic plants are lightweight and will float around the surface of your tank, if allowed. This special string is ideal for attaching plants to rocks, coconut husk huts and pieces of driftwood. After the plants have taken root to the surface, the cotton thread dissolves gradually, leaving no trace. Can I use this plant string in any tank? Yes, the SunGrow Cotton thread will not affect your plants and pets. The quiet dark green color of the plant string is designed to be so similar in color to its original counterparts that it remains inconspicuous and doesn’t take away the sheen from your amazing underwater habitat. The discreet thread can be used in shrimp and betta fish tanks, freshwater community aquariums filled with guppies, mollies, and tetras or an all-plant water terrarium. Are there any other uses for this special cotton thread? You may use SunGrow’s thread in home gardening and do-it-yourself activities. The 65 feet (20 meter) length of Cotton thread can easily be cut into smaller lengths for various projects. The plant string works great attaching vines and flowers to trellises for one-of-a-kind outdoor decor. Many festivities involve helium-inflated balloons; attaching balloons to this string has no negative impact if they float away.
