## Questions & Answers

**Q: What is ph balance of cubes? Do you need to change it?**
A: It's the ph of the nutrient solution that's important and must be controlled, as ir will soak the rock wool cubes.

**Q: do you remove the paper?**
A: I leftbthe plastic wrapper on while growing the seedlings but took it off when it planted

**Q: Do I have to soak these in water first before placing clones or seeds?**
A: You can put the seed in dry and then wet it. With a clone it may be better to wet it first to make it a little softer.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by C***E on January 22, 2024*

Pretty straight forward! They work and they hold up after soaking. Some don't. Happy with quality.

### ⭐⭐⭐⭐⭐ Great product
*by R***R on March 31, 2025*

Perfect. Packaged well. Super fast shipping.Thank you

### ⭐⭐⭐⭐⭐ Good old fashioned rockwool cubes
*by S***S on August 17, 2023*

These are rock wool cubes and they are the right size for what I needed. And if you know anything about Rockwool, You know that it's pretty much all the same. Anyway, these absorb liquid and hold it well. And they don't have any organic matter in them so you can tailor what you feed your seedlings or cuttings without getting anything extra in there.
