    Quillaja Saponaria Extract Powder 20 BuildASoil is proud to partner with Jay Plantspeaker to offer 2 premium Versions of Quillaja Extract.>=20% Saponin for general use>=60% Saponin for when the most potent is wanted How much Saponin is in your wetting agent? ************BEWARE: There are many low quality versions available because of a recent shortage from premium food grade suppliers. (The industry went crazy because they use the food grade Quillaja in Vaccines) Because of the shortage in the market place, we went to great lengths to secure and only provide the highest quality tested and verified Quillaja on the market. You'll be happy to know both versions are crafted from tested food grade materials. This means that both versions pass strict testing for Saponin, Heavy Metals, Pathogens and any adulterant. We are proud to offer you the original and the best.  Warning: Saponins May be harmful to fish. Please use with caution.************Because there is a such a difference in quality levels available and to further distinguish ourselves we are now labeling our products with the Saponin Percentage Minimum. BuildASoil customers absolutely love the Quillaja Extract 60 but have been asking for a more cost effective version for soil drenching and more regular use. Jay Plantspeaker and I have worked with our favorite supplier to offer our most natural version. When the quillaja tree bark is processed for it's saponin it goes through a process that will create a 20% saponin extract with the LEAST amount of processing. This makes the Quillaja 20 the least processed and most natural version.If you are after our premium Quillaja 60 for foliar spray or any reason, it's still available over here.Speak your plant's language! BuildASoil proudly welcomes the famous Jay Plantspeaker to our LEGEND SERIES to help you communicate with your plants in a truly meaningful way. Maybe your plants won't speak back, but they will show you they are happy. Using saponins found in Quillaja Extract Powder for your garden is an absolute game changer. This natural wetting agent makes water 'wetter' and foamy allowing for even spread. Made from the organic Quillaja (Q-Ya-Ha) Saponaria Tree, we can't speak highly enough of this plant extracted source of Saponins.
