1. Demonstration tests to quantitatively clarify the green amenity
effects of indoor greening
2. Design, construction, management, and evaluation methods forindoor greening that stimulates the five senses
3. Research and development in collaboration with the building
industry in the field of biophilic design

4. Development of seamless basic technologies necessary for
urban greening as green infrastructure from indoor greening
5. Creation and development of new green businesses throughcollaboration with a wide range of related companies andpartners
6. Development of basic elemental technologies to support
various SDGs, such as globalization of indoor greening

Basic Planet Hydroculture Composition
The ability to grow many roots (main roots,lateral roots, and root hairs) is important
for air purification, longevity, and disease
and insect control.

Lecaton
Pafcal chip
Silica soil

Outer root from slit in inner container

New Hydroculture
Lecaton

Pafcal chip contains organic fertilizer and works withmycorrhizal fungi to deliver nutrients to the roots ofplants. It also improves the moisture balance in the pot,
and the roots grow throughout the pot.

Pafcalchip

LecatonSilica soil
Pafcal chip
LecatonRoots grow in search of water in the bottom of the pot.
It is difficult for the roots to reach the top, and it takes
time for the roots to spread throughout the entire pot.
Therefore, it is important to note that the roots areconcentrated in the lower part of the pot, the plant is
wobbly, and the roots of thin plants tend to break off.

This lightweight material is made by crushing waste
glass bottles and firing them into foam. Silica (silicicacid) is absorbed by plants as a trace element andthickens the cuticular layer on the surface of plantleaves, making it difficult for pests to attach to plants
and increasing their photosynthetic capacity. It also
purifies water. Because it is porous, it causes the roots
to branch out and the number of lateral roots toincrease, thereby increasing transpiration and airpurification.

Planet Soil energizes the roots andenhances environmental purification.
No need to worry if you use nanobubble water with high oxygen
content even in deep water!
*Not necessary if properly managed with a water level gauge.

The natural world in the wild is growing vigorously without the use ofpesticides or chemical fertilizers. Mycorrhizal fungi living symbiotically inthe roots and various microorganisms around them select nutrients andproduce a strong plant constitution.
Natural organic hydroculture incorporates the mechanisms of the natural world.

Planet's original organic fertilizer (POF), created by pulverizing plants
into a fine powder and fermenting them with four types ofmicroorganisms (partner bacteria), is included in the pafcal chip to feed
the entire root system.

Planet's original organic fertilizer (POF), created bypulverizing plants into a fine powder and fermenting themwith four types of microorganisms (partner bacteria), isincluded in the pafcal chip to feed the entire root system.

Pafcal chipFresh air contains 79% nitrogen, 20.95% oxygen, and 0.04% carbon dioxide.
*Plants cannot absorb nitrogen from the air, but nitrogen-fixing bacteriasuch as rhizobacteria, partner bacteria, and Frankia convert nitrogen intoamino acids and supply them to plants.
【Partner Bacteria】

Soybean and rice bran powders are added to molasses
and manufactured by four types of microorganisms.

1.Bacillus sp.
2.Bacillus thuringiensis
3.Paenib bacillus rhizosphere
4.Pseudomonas sp.

❹Effective against insect pests such asladybugs
