Review: Quality - Highly recommend plant growth is awesome my plants look fantastic
Review: 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!
