Growth Technology GT Silica Liquid Mineral Additive w/Potassium Silicate for Plant Support, Strong Roots & Healthy Foliage – Indoor Houseplants, Outdoor Gardens, Trees & Lawn Care – 1 Quart (946 ml)

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!

Outfreakingstanding!!! A must have for expensive tropical plants !

You have to make sure the pH is okay before you water your plants but it has been working well so far. Will buy again

It damage all my plants the fertilizer from this brand too and it is really expensive

I have only been using it a few weeks. I can tell a big difference already! Ordering a liter now!
