Algae naturally occurs when light interacts with water. Nutrients, such as nitrogen and phosphorus, along with CO2 support the algae's growth and you will start to see it appear on your seed pods and perhaps on parts of your garden itself.

Algae is not harmful to your plants but can be a little...yucky. If it bothers you, simply wipe it away with a clean, damp cloth or paper towel and do a full rinse & refill of your garden's reservoir. Be sure to cover any empty pod holes with our plant spacers and leave those pod labels on your seed pods. These actions help prevent light from creeping into the water bowl and helping that algae to bloom.
