All about wicks

Wicks are the little white sticks that transfer water from the tank to the plant pod.

Wicks are generally very long lasting and do not need to be changed unless you are having some trouble with them.

To make sure your wicks stay working for as long as possible, there are two things that you should keep in mind.

Do not leave any empty cups in the garden

If the cup is empty and there is no soil to receive the water, the wicks may clog up quicker. After removing a plant, we would recommend adding a new one immediately.

If you wish to keep one of the cavities empty, we suggest you remove the cup from the garden and cover the hole so no light would shine directly to the water tank.

Fill you garden to fully each time you water it

Unless you are experiencing mold or algae* in your garden, we would recommend keeping the water level topped up to preserve the wicks as long as possible. We have found that wicks last longer if they are always at least half-way immersed in the water.


Hi, Thanks for the information. Very useful!

I have a quick question.

Do the wicks become less effective in water which is very hard? Can I dip the old wicks overnight in decalcification solution that I use for cleaning espresso machine and then dip in fresh water to make it perform better?

Thank you for the comment!

The wicks are quite long lasting, but can become less effective and hard over time. We have noticed this when gardens have been left unused for a while. Your option sounds good and could help. We also recommend to wash the wicks with soap and roll them between your fingers to soften.
Finally, we also offer replacement wicks in the web store if you just want to replace them with new ones. Price for the 9 pack is $1.95
