How can I request a donation from GreenStalk?
We are passionate about giving back to the community and helping people grow their own food. If you are a teacher or administrator in charge of a charity or educational garden, please email us at firstname.lastname@example.org. Please note that due to the number of requests that we receive, we are unable to donate GreenStalk Planters to individuals at this time.
Is the GreenStalk available internationally?
We currently are only able to ship our products within the United States and Canada. We hope to expand to other countries in 2022.
How long does the water sit in the reservoir?
The GreenStalk's patented slow drip watering system allows water to drain thru the system within about 5 minutes. If used correctly, there will be no sitting water anywhere in the system. The bottom of the GreenStalk includes little ``feet`` that allows water to drain out and away from the planter.
Can the GreenStalk Vertical Planter be used indoors?
Our planters can be used indoors. We recommend adding grow lights based on your growing environment, and adding a GreenStalk Mover or Ultimate Spinner would be a necessity for ensuring water doesn't drain out onto the floor. Please note that water cannot be held for an extended amount of time in either GreenStalk Base and should be allowed to drain into another container.
What can I grow in the GreenStalk Vertical Planter?
A wide variety of vegetables, strawberries, flowers and herbs grow well in the GreenStalk Vertical Planter. We recommend growing larger plants in the GreenStalk Original and smaller plants in the GreenStalk Leaf.
Do I need special soil to use the GreenStalk?
The GreenStalk team's favorites are Fox Farm, Espoma, and Pro-Mix brands. However, any high quality, lightweight, moisture-retaining, potting mix would work well. Avoid using topsoil or garden soil.
I have a GreenStalk Vertical Planter and I would like to add another tier to expand my garden. Where can I get that?
