About Plant Factory Business

We conduct the business by ourselves from the design and the operation for cultivation facility using artificial lights to the sale of crops.
We can totally support such as selections of lights and instruction about cultivation method and so on in the business model for plant factory.

About Life Science business

The enclosed-type plant factory has problems such as high-costs of the initial investment and electrical charges for lights and air conditioner;　however, this enclosed-type plant factory can give you stable crop quality and quantity through all seasons.
For the last 10 years, the research about “functional food” has progressed and permeated in the field of preventive medical and food.
We consider that the [vegetal functional food] is the important essence for the life science business, and we also think the plant factory business has potential for not only cultivation but also life science business.

About The Control of Light Quality

We think how to make the best choice of light for the enclosed-type plant factory.
If you don’t consider light quality, you can use fluorescent light because cost is low and maintenance is easy.
However, light control is very important technique when you need value-added harvest with plant factory.
According to basic research of cultivation using the light control, blue wavelength makes leafstalks’ shape good and red wavelength makes photosynthesis high. We actually adopt HEFL light units bluish light in the cultivation of “Tsuburina [ice plant].” Tsuburina has much functional ingredient in their stalks and crispy taste through this technique. If you want to grow leaves, you need to use red wavelength to increase weight of crops.
We think it is important to choice plant to glow in the plant factory and to consider if this plant need light control or not.

Proximity Lighting

• ◆Growing plants healty by 3 wavelength LED.
• ◆Low instllation cost - because of single tip System.
• ◆Possible to select light quality with phosphor.

LED type	cost	heat	growth
3 wave length "wide-band"LED	○	◎	◎
Single tip (psuedo-white)	◎	◎	×
Multi tip system	×	×	○

	Old multiple LED could NOT become popular In plant Factory owing to high product cost .			3wave length LED type can solve these ploblems.
	Old　single tip system does NOT grow plants healthy because of NOT existence of red wave length.			Low costs and having red wave length!

3 wave length "wide-band" LED lamps
[panel type][Super thin]

• ◆New lamps keeps Photon flux density well, even if there are long distance.
• ◆Flexible control of Light quantum. You can raise maximum is 400μmol/m²/s

Optimum for　making seedling

You can customize various wavelength by changing the phosphor.

Product specifications are subject to change without notice.

Product specifications are subject to change without notice.

Red-white

• ◆Red wavelength(610-660nm)is covered.
• ◆For all vegetables.
• ◆Expected for augmentation of Photosynthesis.

Blue-white

• ◆For healthy forming and increasing Vitamins.
• ◆For acceleration of flower bud.

3 wave length "wide-band" LED lamps　
[fluorescent tube type][G13 type]

• ◆Proximity lighting is allowed. Because surface temperature is lower than old fluorescent light.
• ◆Effective in saving cost of air-conditioner.
