How it works

The plantstraws will keep your growing medium moist, thus helping your plants stay hydrated and happy by allowing it to sip away on a larger container of water such as a nice vase!

It is a self watering wick system - capillary action wicks water from one side to the other, and the surrounding metal tube prevents evaporation on the way.


The plantstraws are assymetrical, with one end being longer than the other. This is to create a variety of possible setups, play around with it to figure out how you want to use it! Which side of your plant do you want facing forward? What vase to use and on what side of the plant to put it? Will you need to raise either to create a perfect combo? 

Water level below soil level

When the water level in your vase is at or below soil level, the main force in action is a capillary driven flow from the wetter to the drier side. This is slow and you might feel like the water level in your vase isn’t moving, but the plant takes what it can and needs. If you see signs of under watering, digging down a longer section of cord helps.

Water above soil level

When the water level is above soil level, gravity will create a light pressure through the cord pushing water forward. 
The bigger the height difference is, the higher the pressure becomes. This could potentially lead to the vase being emptied faster than your plant drinks, with possible risks of overwatering or leakage. The high arch shape of the plantstraw minimizes the risks, but keep an extra eye on your plant if you’ve created a pusher setup.


1. Water the plant and soak the planstraw until the cord is thoughly wet
This step ensures enough water is avaliable to create the capillary driven flow from your vase to your plant, so it’s really important! Do not skip!

2. Pull forward around 5-15 cm of cord on the plant side of the plantstraw
A longer cord in the soil allows for more water to your plant. Consider the size of your pot and the thirstyness of your plant when deciding how long cord to use. You might need to adjust this if you see signs of over- or underwatering, so keep an eye on your plant to see it’s reaction.

3. Use a chop stick or similar to dig a steep hole and lead the cord followed by the straw into the soil
Lead the cord as close to the roots as possible. The little mark on the plantstraw indicates a recomended minimum level to hide under the soil. This is to prevent evaporation, as drying of the cord could possibly break the flow discribed above.

4. Lead the other end of the plantstraw into a nice vase, straighten things and you’re all set!


Take care of your plantstraw and it will last a long time! 

Cotton cord

When removing the plantstraw from your plant, cut away the dirty part of the cord and leave it to dry completely before storing it. The cord can also be replaced with the help of a thin flexible string. 


The metals will recieve patina in contact with water, air and soil. All planstraws can be polished to near original glow using a suitable household polish.   

Caring for plants 

I recommend keeping an extra eye on the plant in the beginning to see how it reacts. Be aware of signs of over- or underwatering and if necessary adjust your setup accordingly! Depending on your plant, perhaps you won't have to give any extra water for ages! With heavy drinkers such as an big leafed trees or thirsty cuttings, you might not have to water everyday but once a week.
