Bio Jolt 1.5 can add about every 10 - 14 days throughout the plant's life, to ensure as much biological activity in your medium as possible. Think of it like "energy drink for your plants". It's a biological blend in a bag, there to encourage plant vigor. Bio-Jolt is excellent for teas - either by adding it to your own tea or using it on its own. Works well by also adding in the Rhizo Charge, giving your plant's roots even more food for those mycorrhizae that are already colonizing in the root zone. Bio-Jolt is known to show an almost immediate response, a noticeable plant reaction within 12 - 24 hrs.
