(1)The quality of the seeds you purchase plays a crucial role. For optimal results, we recommend buying seeds from reputable brands that are suitable for hydroponic devices and compatible with the temperature conditions of your environment.

(2)When using the manual mode, ensure the correct ratio of nutrient solution to water, avoiding excessive nutrient concentration. Also, maintain a distance of approximately 4 inches between the LED lights and the plants.

We do not recommend reusing the sponges as they may not perform as effectively as the first use. Additionally, reusing sponges from previous plants can introduce bacteria and potentially lead to disease. However, the white baskets and blackout covers are able to reuse after a thorough cleaning. To support environmental sustainability, we offer cost-effective sponge refill packs at a discounted price on our official website, www.letpot.com, or the store where you buy your hydroponics system.

When the plant's roots grow well (visible white roots extending from the sponge), you can transplant them from the hydroponic system to other pots or garden. All our sponges are made from biocarbon materials that can degrade in the soil without causing harm to the environment. Therefore, transplanting the plant with sponge together can enhance survival rates.

If the LED lights are not turning on, try pushing down or reinserting the extendable rod into the bottom until you hear a "Beep" sound. Then press the "POWER" button to activate the lights. If the lights still does not work, please contact our customer service for assistance. Please note that while hydroponics system's light board is equipped with a nanocoating for water resistance, it is best to avoid direct contact with water to prolong the lifespan of the lights.

If the water pump is not functioning or experiencing issues, it is usually due to blockage caused by impurities in the water. You can refer to the HOW TO CARE & MAINTENANCE section to clean the water pump. If the problem persists, please contact our customer service online or via email, and we will promptly assist you.

When you successfully connect hydroponics system to Wi-Fi, the settings will be retained even after a power outage. However, if your hydroponics system is not connected to Wi-Fi and the app, it will revert to the default settings after a power interruption.

Mold growth is often influenced by water quality and air humidity, as well as the quality of

the seeds you purchase.

Here are our recommendations for seed selection:

A. When purchasing seeds, check the seed's shelf life.

B. Avoid buying and using white or green seeds. Look for high-quality seeds with darker colors like gray, brown, or black.

C. Examine the seed's surface. Look for seeds with a lustrous appearance that can reflect light. They should also have a sturdy and smooth texture.

D. Consider the symmetry and shape of the seeds. Look for seeds with symmetrical and teardrop shapes, as deformities or unevenness may indicate poor seed quality or immaturity.

E. Purchase seeds from reliable brands and distributors.

To prevent and treat mold/algae buildup, here are the solutions:

A. Thoroughly drain and rinse the water tank, discard any sponges or plants that have come into contact with mold/algae, and clean the used planting baskets and covers. Keep all accessories used in the system clean.

B. During the planting and seedling stages, cover the sponge and the top of the white

baskets with our seed pod stickers. Also, use the blackout covers to shield unused pods to prevent the water tank from being exposed to light, which can promote mold and green algae growth.

Under normal usage, the water pump does not require regular cleaning. We recommend cleaning the pump and its filter sponge after at least six months of use. If you wish to clean the water pump, please follow the steps below:

Step 1: Turn off the power and unplug the power cord.

Step 2: Press the latch on the side of the water pump to open the pump cover.

Step 3: Remove the sponge in front of the water pump and rinse it with clean water. Avoid using detergents as they may disrupt the nutrient balance. If the sponge is heavily soiled, you may also consider rinsing the entire water pump by soaking it in clean water and gently shaking to dislodge any debris.

Step 4: Reassemble the components and restart the machine.

If you require instructions for disassembling the water pump for deep cleaning, please contact us, and we will provide you with a cleaning guide.

If you notice dirt or debris inside your water tank, we recommend using a soft, damp cloth or wet wipes to wipe the interior. Then, turn off the power, unplug the power cord, remove the light board and extendable rod, and rinse the water tank with clean water. Avoid using detergents as they may adversely affect plant growth. During the cleaning process, ensure that the light board, extendable rod, and power port do not come into contact with water, as this can cause circuit damage. Also, try to prevent direct contact between hydroponics system's screen(MAX/PRO) and water.
