Q & A

Questions and Answers (1)

can you use these in active hydroponics, such as DWC?
Some people do use a blend of pebbles and coco, but what you need to be aware of is that the cellmax retains more water than the pebbles, and is perhaps suited to flood and drain or hydro dripper system rather than a DWC system.
