    Purived
  • FEEDS HOUSE PLANTS INSTANTLY: Purived Houseplant Food is water-soluble, so it feeds instantly - giving plant an immediate balanced supply of macro-nutrients (NPK) and micro-nutrients.

Purived Houseplant Food contains all 7 essential elements to aid in maintaining a healthier soil.
  • ALL-NATURAL & EASY TO USE LIQUID FERTILIZER: Purived is a super concentrated all-purpose liquid plant food. One 20oz bottle makes 50 gallons of nutrient rich liquid houseplant fertilizer that's easy to use! Add 1 cap full of Purived to 1 gallon of water. Feeds flowering house plants, foliage type plants, succulents, edibles, cacti, and more. Plus, unlike most liquid houseplant fertilizers, Purived is odor free!more
