Youâ??re right latewood I should have said drip type systems, or even ebb & flow but in a DWC system or an Aeroponics system where you water from the bottom Rockwool works fine.
Zandor Reviewed by Zandor on . Help I can't manage to get beyond seedlings!!! Can anyone tell me what im doing wrong and give me some pointers. Three times now ive managed to germinate my seeds in tissue and transplant them into rockwool and once they reach about an inch tall they stop growing and eventually die. The first lot dried out the second lot look like there about to die from OD on nutrients. If I tell you what ive been doing perhaps someone could give me some pointers. Ive Ph balanced about 2 litres of water to 5.6 added about a teaspoon of superthrive. Rating: 5
