II. FAQs about the MAX hydroponics growing system
Questions about MAX's automatic watering
Note: Please do not set the switch of automatic mode when the water in the equipment is at full level, it is not effective.
1. The ‘Auto’ mode is turned off by default when the machine is powered on. There are two ways to start the ‘Auto’ function: press the pump button on the screen panel for 3 sec or open the ‘Auto mode’ on the APP directly. To be attentive, the machine shall be with the low water level in the water tank when turning on auto-adding water. Otherwise, it will trigger the protection mechanism to close the auto function.
2. While auto-adding water, the machine will refill the water tank from the external reservoir when back to the low water level, stop to add water when the floater reaches the max water level, then inject the appropriate proportion of nutrients. It's about 2-3 secs, so you may not notice it.
3. While auto-adding water, if the pump has worked for 5 minutes and the floater does not reach the max level detected by the sensor, the machine will automatically turn off the auto mode and report the error. The water icon on the panel will flash, and the App will push a notification to remind you of the abnormal.
4. Some reasons for abnormal situations about adding water: 1. lack of water in the external reservoir; 2. the floater blocked and unable to flow with water; 3. the water pump damaged.
PS: If the pump is damaged, plz contact LetPot’s customer service mail in time.
5. If you meet the problem of ‘automatically jump to close the auto mode’, plz check the machine first, referring to the above conditions and sorting it out, then restart the ‘Auto’ functions.
If the product is faulty, take a photo or record a video and send it to LetPot APP will get LetPot engineers to analyze the problem.

III. Use and Maintenance of Hydroponic Growing System
About when should the nutrient solution be added
When the water tank is running low, you can simply replenish the water and nutrients at the same time. Typically, LetPot recommends a ratio of water to A&B of 1L:5ml. This formula is suitable for the growth of most plants. No additional plant food is required. For advanced users, microelements may need to be added according to different plants, growing environments, and water quality.
About the circulating water pump work
The water pump operates in a cycle of 30 minutes of work followed by 30 minutes of rest when the switch is turned on. This cycle helps to increase oxygen in the nutrient solution, promote plant root respiration and enhance nutrient absorption. So that it keeps working in a cycle. When the water pump switch is off, the water pump will stop working.
About the power consumption
We have computed that from the LED fill light, the power is around 24/36 watts (Senior&MAX) when turned on, and around 5 watts when turned off. This amounts to 0.424 kWh when calculated for one day, where 0.024 kWh is consumed for 16 hours and 0.005 kWh is consumed for 8 hours.
0.024*16+0.005*8 = 0.424 kWh (Senior)
0.036*16+0.005*8=0.616kWh(MAX)
IV. Cleaning and Maintenance of Hydroponic Machines
About cleaning the water pump of the hydroponic growing system:
Just need to remove the pump cover (snap-fit structure), rinse the sponge inside with water or detergent, and then press it back. Only the sponge needs to be cleaned.
About cleaning mold in the hydroponic growing system:
As per LetPot botanist advice, we suggest immediately emptying all the plants and thoroughly cleaning the water tank of the hydroponics growing sysytem. General non-corrosive detergents can be used to clean equipment and parts. It is best to dry it or place the equipment under sunlight or UV light to completely eliminate the mold place for a few days before starting a new planting cycle.
