Stop using rockwool in DWC. It's the worst medium to start seeds or clones in DWC. Sterilized jiffy/peat pucks work very well for seeds.Hi Guys,
Not new to this forum in terms of reading but newly joined to post. Not a complete beginner having done a few successful rounds on NFT but recently decided to venture into DWC for a change and to try something new. Problem is i seem to be falling at the first hurdle. I'm hoping someone can maybe point out something i could be doing wrong. OR perhaps just a bullet proof method they use that i can maybe mirror for the first part.
The problem is moving the small rockwool cubes to the net pots. Ive been doing this after noticing root growth on the underside of the cube. I've put some pebbles in the bottom of the pots (inch ish) and raised the water level of the system so bubbles ar kinda on the line of the bed of pebbles. Then put the remaining pebbles around to fit. Temp around 70f, ph around 5.9, chiller keeping food around 68f, EC about 1.1 (EC according to guardian)
Even after a week or two they don't seem to carry on growing much or at all. And some just die. I'm not top feeding as i think the cubes are keeping wet and i dont want to over water either. Only a 48w T5 propagation light in there but they're only about 2 inches high so assume that's sufficient?
Any ideas?
You got saturated rockwool cube with hydroton capsulating it with moisture. Best thing is to to run clones in straight leca/hydroton. No possibilities for a anaerobic environment and low DO that way.
