## Questions & Answers

**Q: I have a grow table that is 94.5 " x 22.5" x 6".  how many bags do i need?**
A: 94.5*22.5*6/(61.0237in3/liter)=209 liters.  And since the bags come in 10l, 25l, and 40l sizes, 21x 10liter bags, or 9x 25liter bags, or 6x 40 liter bags.

**Q: Where is this medium produced (I've read much of it is made in China and Germany)?**
A: For the person that says it doesn’t matter where it’s from, it really does. China sprays chemicals on their products and FDA has found  lead and formaldehyde in almost all their products with natural materials used. So you see, it does make a difference when you are using for plants that you consume. At least some of us care what we are eating.

**Q: I have 5  6in grow baskets how much willit take to fill them**
A: As "ellz" commented earlier, you should be able to fill them with a single 10 L bag.

**Q: Does shipping come in box?**
A: Just like any other product you received from Amazon it will come in an Amazon box further securing whatever package the manufacturer uses. They would never miss out on that marketing opportunity.

## Customer Reviews

### ⭐⭐⭐⭐⭐ The best leca product there is, basically an industry standard
*by A***Y on May 26, 2025*

If you require these, you already know what you need them for. The build quality is excellent. They are simple to setup and easy to use. They do an outstanding job of storing and transporting your water & nutrients. These are the golden standard of leca. Absolutely highly recommended.

### ⭐⭐⭐⭐⭐ perfect item
*by A***H on July 21, 2025*

arrived quick and item was perfect. thanks

### ⭐⭐⭐⭐⭐ Good value for starting semi-hydro
*by C***C on April 21, 2025*

Starting my semi-hydro plant journey and bought these. They're not like the perfect orange-y colored balls that you see some people using. These are a regular brown color and are more irregularly shaped, but that's fine for me because I had read it's actually easier to situate your plant in the irregular-shaped leca instead of the perfect balls. For the most part these haven't sunk after soaking them in water (even after soaking for weeks), but I don't think that really matters as far as actually using these for planting because none of the plants I've moved to leca have died and it's been a couple months now.
