Question 28: Will airstones at the bottom of a flooded container work with Grow-Cubes™?
Answer:
Airstones will not provide enough oxygen in a stagnant system. You
may still risk root rot with the plant's roots sitting in water.
Also the plant's roots get lazy when they are being fed constantly.
Grow-Cubes already have a high air capacity, but still hold plenty
of moisture (much more than expanded clay). The best use of Grow-Cubesis
on an ebb and flood tray (flooded 1-4 times per day) or by top feeding.
You can place the airstones in your stock tank for added oxygen.
