** Online Only Price **
This loose fill, non-bagged product consists of small stonewool croutons about the size of a fingernail.
When you use this potting mix the miniature cubes stack on top of each other and air pockets are created throughout the pot.
Growcubes are difficult to overwater if the container has good drainage. The Grow-Cubes are a lightweight alternative to your regular potting mix.
You can use Grow-Cubes in any size pot and in many different growing systems, such as ebb & flow, top watering, or just with a watering can.
Good results have been seen even with continuous watering. The Grow-Cubes do not need to be changed, as they last for the life of your plant.
If you are new to hydroponics, then this is the product you should choose. Complete with package instructions, Grow-Cubes are easy to use and reasonably priced.
Comes in a box of loose mini-cubes. 5.3 cu ft/150 L.
