Green algae that form on the surface of the growing medium are a common occurrence in soilless cultivation environments and do not affect plant growth.

However, if you wish to remove the algae for aesthetic reasons, gently scrape off the affected areas. To prevent further algae growth, cover the exposed surface of the medium—especially areas exposed to sunlight—with a light-blocking sheet (such as black nonwoven fabric or aluminum foil).

Be mindful not to seal the surface too tightly; excessive humidity on the medium can accelerate algae formation, so ensure there is adequate ventilation.

⚠️ If the water level in the basin remains above the recommended level for extended periods, oxygen supply to the roots may be disrupted, potentially leading to microbial growth. Please monitor the watering status either via the app or visually, and maintain appropriate water levels accordingly.

If pests are found on plants grown in the BALCONYFARM Pot, they may have entered through various routes — such as from nearby outdoor plants or through open windows.
To prevent infestations, maintain a stable indoor temperature and humidity, and avoid weakening plant roots.
You can also use companion planting by growing strongly scented herbs like rosemary, peppermint, or basil nearby to naturally repel pests.
 Alternatively, you can make natural insect repellents at home:

Tips for Making Natural Plant Repellents!

• Vinegar Spray: Mix water and vinegar at an 8:2 ratio and spray on both the front and back of the leaves.

• Garlic Spray: Crush one clove of garlic, mix it with 500ml of water, let it sit for a day, and then spray onto the leaves.

• Egg Yolk Spray: Dilute one egg yolk in 500–1000ml of water and spray directly onto affected areas.

• Repeat the spraying 2–3 times a day for 3–5 days until the pests are eliminated.
