## Questions & Answers

**Q: Can you reuse these?**
A: No.

**Q: I would like to use them to start some cuttings.any one has tried it?**
A: Yes they work great! Make sure to follow the directions on the manufactures website. Grodan101.com or check out this video. https://youtu.be/luwxbCT1QCY

**Q: Are these cubes ph neutral?**
A: GRODAN stone wool is pH Neutral! It is a common misunderstanding that GRODAN is alkaline and that one has to continuously adjust the pH, when in fact stone wool is pH neutral. ... Begin by saturating the stone wool in pH 5.5 water ½ hour before use. There will be a rise in pH of about 1.0 from the residual lime dissolving.
