Frequently Asked Questions

How long does it take to grow?

Herb seeds take 7-14 days to sprout, and will be ready to start harvesting in 2+ months. Continuous harvesting will encourage a bushy plant and greater yield.

How long will it last?

Plants will continue to grow with sufficient nutrients and light; however, after 3-6 months it may develop a woody stem and the leaves will become a bit bitter.

How much sun will it need?

Herbs require at least 6 hours of direct light daily, and should be put in an unobstructed window that faces south, west or east (southwest is the best option). During winter months—or if you don’t have an unobstructed window—you can supplement with a grow light.

Can I put it outside?

Garden Jars are designed for indoor use, but can be put outside. Be mindful that the planter does not have a drain hole, and if the reservoir floods it may drown the roots. Bring your Garden Jar inside if temps dip below 55⁰ or above 80⁰.

How is it reusable?

The net pot and rgrow medium can both be reused—simply rinse with hot water. Add new seeds and use a water soluble fertilizer and follow its instructions.
