Leaves and Growth
Watering Concerns



Why does it come in a glass canning jar?

  • We use clear glass because it lets you watch the roots of the plant develop and see how moist your growing medium is for assessing your plant’s watering needs. The stainless steel net pot and recycled glass grow medium can both be reused—simply rinse with hot water. Add new seeds and use soil or coco pith to help seeds germinate. Use a water soluble fertiliser and follow its instructions, and you can also just wash the jar and use it for something else!

Can my mint or basil really grow in such a small container?

  • Yes it can! We’ve designed Eco Planter with an inert porous growing medium and a wick that transports water and nutrients to the plant roots via capillary action. The nutrient solution (water and fertilizer) are held in a reservoir and taken up as needed, providing the perfect balance of water to oxygen. Herbs require at least 6 hours of direct light daily, and should be put in an unobstructed window that faces north, west or east (northwest is the best option). During winter months—or if you don’t have an unobstructed window—you can supplement with a grow light. Making sure to place your Eco Planter in a place with ample sunlight - it’s the most important requirement for your plants to grow!


Self Watering design

What is the growing medium?

  • Our growing medium are growstones, porous rock that allows to keep moist your plants all the time.

What does the wick do?

  • The wick brings up only the water and nutrients your plants need via capillary action — like a little natural pump!

Why do I have to add fertiliser to the water?

  • With passive hydroponics, as you grow plants without any soil, a nutrient solution (water and fertiliser) is required to provide the water and nutrients to the plant roots as needed via capillary action — this providing the perfect balance of water to oxygen!


Seed Packet

Are these seeds organic?

  • Yes! 100% organic and Australian!

Are these seeds Non-GMO?

  • Yes, all of our seeds are Non-GMO.

I think you gave me too many seeds.

  • Those are our gift to you! Be sure to save them for a second planting or use them in another container to grow more mint.

What kind of mint or basil is this?

  • The mint variety included in your Eco Planter is actually lemon balm. Lemon balm is in the mint family, and we use it because it grows really well in small spaces like your jar while still giving you that fresh minty taste!
  • For Basil is an Organic Sweet Italian Large Leaf Basil that will grow well indoors and outdoors.

My seed packet says it is expired...

  • Seed packet dates are a funky thing - don’t be alarmed if the date on the packet has passed. Your seeds might be slightly less fertile, so plant a few extra in your jar to make certain you’ll have plenty of seedlings to choose from.



Where in my home should I put my Eco Planter?

  • Eco Planters 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. Your Eco Planter will do best in a north-facing window with full sun (6-8 hours per day). If you don’t have a window that gets lots of light, it may be best to use a grow light (check this space for our soon to come recommendations).

What’s the best temperature for my Eco Planter to grow in?

  • Bring your Herb Jar inside if temperature dip below 12C above 26C. Your Eco Planter will grow well in normal room temperature (21-24 °C). Keep in mind that in higher temperatures, your mint or Basil will need more water to keep growing. Additionally, if temperatures are below 12C degrees most of the day, your seeds may be slow to germinate.



How many seeds do I need to plant?

  • We recommend planting 7-10 seeds spaced evenly around the jar opening. If you planted the whole packet already, no problem. You may just have a few more seedlings to trim in the next couple of weeks.

My seed packet has more than 10 seeds - what do I do with them?

  • Our seed packets always come with extra seeds for you to save for another planter of yours!

Why push the seeds ¼” (.6 cm) into the grow medium?

  • Your seeds need a warm, moist environment to germinate, and the light ¼” blanket of soil is perfect for that. If left uncovered, the seeds may not be moist enough to sprout, but push them too far into the soil and they may never have the chance to peek their heads up. We’ve found that ¼” is the goldilocks of depths – not too shallow, not too deep, but just right!

How long is 0.6 cm?

  • Use the width of your pinky nail as an estimate for 0.6cm.

What will happen to my seeds when they germinate?

  • The germination process is the very beginning of your seeds turning into full plants. From Day 7 to Day 14 of growing you should start to see small seedlings appearing from underneath the soil and begin turning into sprouts.

How long will it take to grow?

  • Our seed packets state that seeds should germinate within 2 weeks, and will be ready to start harvesting in 2+ months. Continuous harvesting will encourage a bushy plant and greater yield. If that’s not the case for you it may be due to non ideal environmental conditions. If temperatures are below 12 °C for most of the day or if your jar isn’t getting much light, your seeds may germinate slowly or not at all. This is why we’ve given you extra seeds! Try planting the leftover seeds for better luck. If none of these tips work for you, just contact us and we'll happily help you out!

Do I need to transplant my mint or basil plant into a larger container?

  • No transplanting necessary! Your mint will have plenty of room to grow inside the jar.

How long will my herb plant last?

  • A basil plant will continue to grow with sufficient nutrients and light; however, after time it will develop a woody stem and the leaves will become a bit bitter.
