Grodan Grow-Cubes 1/4 rockwool cubes - 1 gallon size – QuarterAcreOrchids
Rock wool Grow-Cubes are a wonderful additive to soilless orchids mixes the 1/4" cubes retain their shape while allowing for great airflow and superb moisture retention. Perfect when mixed with clay pebbles, or mixed in with traditional orchid mixes.
For growers seeking a forgiving, easy-to-use loose-fill media, Grodan Grow-Cubes are an excellent choice. Composed of uniform 1/4” cubes of rock wool, Grodan Grow-Cubes offer many advantages over other soilless potting mixes:
- Grow-Cubes do not compact and compress together, but instead, stack inside the container leaving air pockets which guarantee the roots constant access to oxygen, promoting high metabolic rates and continual root development.
- Grow-Cubes drain easily, naturally retaining a 50% water to 50% air ratio.
- When mixed with non-restrictive media (e.g. expanded clay balls) a very desirable blend of root aeration and homogenous moisture content can be achieved for extremely vigorous growth and bloom.
Lightweight — approximately 1/10 of the weight of a bag of potting soil.
