The grow bags are sturdy and reusable, and the watering kit should continue to work with yearly replacement of the batteries. The components of the G3 Grow Formula are used up after each season and will require replenishment to continue providing the 70 micro and 3 macro nutrients for the next season. After the Kickstarter is fulfilled we intend on making the G3 Grow Formula purchasable by itself to enable you to have some available for each season and to build up a stock pile if wanted.

Everything in the kits except the seeds are shelf stable and will last decades. The seeds are expected to last 2-3 years before the germination rate will drop off, but unfortunately will need to be replaced after that time.
