So what is this newly formed dark green substance on your yCubes? If it resembles either of the images below, you may have some algae growing. No need to worry.
What causes the algae?
Algae grows when it comes into contact with light, nutrients, and water, so can easily form once you’ve added plant food to your Gardyn system.
The good news is it does not pose a threat to you or your plants, but could potentially cause a delay in the root developing and invite some unwelcomed guests on your Gardyn.
The good news is you can remove the algae by gently washing it off with tap water.
Be mindful to not damage the plant.
To prevent algae from forming, you want to remove one of the sources it needs to survive. The easiest one to control is light.
First of all: all spots shall be fully closed so that no light can enter in your device.
If you have any empty yPod, cover it with one of the caps you received in your welcome kit. If need more than what you received, they are available for purchase on our website here.
The next step is blocking the light with your growing plants. You can easily do this by following the steps outlined below.
Cut a 3"x3" foil square and gather the plant pod you want to cover
Cut a slit in the foil to the center.
Gently pop up the yCube out of its pod.
Slide the foil over the yCube, threading the stem through the slit made in step 2.
Fold the excess foil down over the sides of the yCube. Do not tear the foil! Tuck edges against yCubes so they stay inside the pod.
Press the yCube back down into the pod
Return the plant to the Gardyn system! Remove the foil when the plant is large enough to naturally shade the cube.
