Q: Why does this hydroponics system require sub-lighting (LED lamps)?
A: This system is for home hydroponics. In balcony or living room, leafy vegetables go through photo-
synthesis is usually lack of required amount of sunlight. And this may cause outgrown plants or thin
and limp leaves. The LED lamp supplements the required amount of light for plants to grow properly.
Q: Do I always turn on the LED lamps for 24 hours per day?
A: No, the minimum photosynthesis time for leafy vegetable growing is 10~12 hours a day.
Q: Who is in charge of installation, repair work after purchasing this product?
A: It is difficult for common purchaser to assemble and install the product because it contains piping and
wiring that allows nutrient solution to flow. Our company and sales agents are totally responsible for
assembly, installation and maintenance.
Q: How and where do I purchase seedling?
A: You can cultivate the seedling on the seedling planter according to the method of seedling cultivation
showed in this guide page 9, 10 and 11. In case of growing seedlings under sunlight, follow instructions
in page 9, 10. (If you purchased our seedling planter, you are able to grow seedlings at home all year
round.)
Q: What kind of plants can I cultivate in this hydroponics system?
A: Romaine lettuce, bok choy, water parsley, etc.
Q: What kind of hubs are possible to grow using this system?
A: Hyacinth, mint, rucola, rose herb, etc.
Q: Is there any nourishment difference of vegetable between garden culture and hydroponics?
A: Whereas for outdoor gardening, nutrients differ dramatically depending on outside factors (temperature,
sunlight) and sometimes plants partially lack nutrients, hydroponic gardening, nutrients are evenly
supplied and special plants can be grown with additional nutrients. Hydroponic gardening produces
softer leaves with better texture compared to outdoor gardening. (Only slight nutritional difference).
Q: How about the growth rate between Hydroponic System in LED lighting and garden culture
in sun lighting?
A: Hydroponic culture is 1.5 times faster.
Q: Is there any yield difference between garden culture and Hydroponics per unit area?
A: Hydroponics produces about 1.5 to 2 times than garden culture in the same area. (According to the
layer quantity of hydroponics, harvest may differs.) The reason is that lighting time is double
(24 hours lighting system) and growing conditions (nutrient, temperature/humidity control, not affected
by the weather, little insect damage) is better in the hydroponics system, so grow more quickly and
increase more harvest.
Q: Any difference of taste and chewing texture between garden culture and hydroponics?
A: Vegetables grown in a hydroponics system are more soft and munchy, so they are often used for
salad material. There is the research report of Japanese Plant Research Institute that lettuce cultivate
in hydroponic system has more nutrients than in garden culture, especially vitamin C is three times in
the hydroponic system with LED lamp.
