Q: Where should I install the hydroponic system?
A: The best place is a sunny and well-ventilated place like balcony and a living room, however, the plants
may freeze to death under the low temperature in winter time, so grow them in the living room and
ventilate frequently.
Q: How much water can the nutrient tank hold?
A: 12 liters.
Q: How much should I fill the nutrient tank at first?
A: Up to the full capacity of 12
ℓ
which indicates maximum level in the nutrient tank.
Q: How much should I refill water in the nutrient tank if alarm-sounding for the water shortage?
A: Power off before filling water. 10 minutes later, fill the nutrient tank with water up to the refilling level (10
ℓ
).
Q: What is the appropriate time to circulate nutrient solution?
A: 10 min. is for the right after transplant seedlings into hydroponic system and 30 min. is for well grown
plants.
Q: How do I dilute water-soluble fertilizer with water?
A: Fill each bottle for hydroponic fertilizer A & B with 200
㎖ of
water and dilute them. Then, use a syringe
enclosed to fill up each 12
㎖
of A & B. Add them and 12
ℓ of
water in nutrient tank and dilute again.
Q: When should I harvest after sowing seeds directly on a seedbed?
A: It depends on the seeds. They generally germinate in the dark place within 3~4 days, and are
transplanted to the planter after 3 weeks from germination. After 2 weeks from transplant, then harvest
is available. Harvest time of plants is about 6 weeks but it is in slightly different due to seasonal and
environment conditions (temperature, sunlight).
Q: How do I harvest crops?
A: If leaves were grown enough to eat, cut the outer leaves. Cut them at least once a week so that the inner
leaves can grow fast. (Recommend to use scissors when cutting leaves.)
Do not cut stems until the crops age and are replaced with new seedlings.
Q: Can I sow the seeds in the hydroponics directly?
A: Impossible.
Q: How long can I harvest the seedling?
A: All seedlings planted in the pots have their own lifespan and cannot be cultivated permanently.
After being transplant to the hydroponics, leafy vegetables age over time (2 months in winter, 1.5 months
in spring and autumn, and 1 month in summer). Therefore, they should be replaced by new seedlings.
(Growth period may differ depending on the type of species.)
Q: How often should I change water in the nutrient tank?
A: If water in the nutrient tank gets turbid, moss will grow and it won’t help for environment of plants.
Replace water once or twice a month to help plants grow well.
Q: What is the proper growth temperature?
A: Proper temperature is different from each plant, however recommend 18~23 ՞ C.
If over 25 ՞ C, plants will be overgrown.
