Secure your plants in the desired position by providing weight to the underwater plants, ensuring they stay anchored to the bottom and do not float to the surface due to buoyancy. This effectively protects the growth of submerged plants. The pot has space to add substrate or gravel, increasing its weight while also providing essential nutrients for underwater plant growth. Accommodate unruly roots, secure moss, and propagate cuttings. The hollow surface allows water and air flow to effectively promote the growth of plant roots and stems. You can easily move the pots to your desired locations without damaging the roots, helping you create an aesthetically pleasing underwater landscape.
