Good quality, though a bit pricey
I saw this brand and product on Sydney Plant Guy's channel and decided to give it a shot! I was looking to add silica to my fertilizer routine to help my tropicals and aroids grow and keep large, lush, strong leaves. I do feel I noticed a difference in their overall thickness/rigidity and sheen. And the variegated portions of my monstera leaves show no sign of melting. It's a dream.However when the bottle ran out I did purchase a different, more concentrated product simply because I have a very large collection and this product is too expensive to use up so quickly.If you have a more modest collection, I would completely recommend this product. It is easy to mix and even though having to wait for the silica to stabilize can be a pain, it works. My plants looked healthier and much stronger after a couple weeks use. I used it in every watering at a low dose. And I used AI to help with conversion rates for measuring

Keeps variegated white plants longer
I bought this as it was recommended to help keep my plants with white variegated leaves stay white longer. So far so good! It also helps the stems of my plants become more sturdy. It’s easy to use. I just mix it with my distilled water and shake it up. I let it sit about 30 minutes before adding my foliage fertilizer and I’m good to go!
