tolstoy21 Posted November 22, 2020 Share Posted November 22, 2020 Can rock wool be used as a medium to propagate plants in pots submerged, or is this something that's better suited for immersed grown plants? If not, what's an easy medium to use in pots for submerged plants? Planted substrate? Link to comment Share on other sites More sharing options...
Administrators Cory Posted November 22, 2020 Administrators Share Posted November 22, 2020 I suppose the scope of what you are trying to do would help. Yes rock wool can work just fine in pots submerged if you're trying to propagate for resell. Link to comment Share on other sites More sharing options...
tolstoy21 Posted November 22, 2020 Author Share Posted November 22, 2020 Yeah not sure on the resale part yet. I'd say, maybe? I need to thin out some crypts and wanted to grow out the small ones shooting up in the soil in some of my grow-out tanks. Not sure yet if I'm going to try to sell or trade them or not. Just depends on how many I accumulate. Are there any caveats to rock wool? Link to comment Share on other sites More sharing options...
tolstoy21 Posted November 22, 2020 Author Share Posted November 22, 2020 Also @Cory, I blame your root tabs. I used them. Now I have too many crypts. 🙂 Link to comment Share on other sites More sharing options...
