Polyaminoacid products for root-zone performance in controlled-environment
horticulture — developed for substrate-grown crops such as soft fruit, where
water, nutrients and biology all act in the root zone and where growers judge
value on routine performance every cycle, not on a rare rescue.

TWO PRODUCT CONCEPTS, ONE ROOT-ZONE PLATFORM

Soluble root-zone conditioner

Applied through fertigation. Designed to
improve nutrient availability and stability in
the root zone, manage ions in real irrigation
water, and support biological inputs —
recurring value in every irrigation cycle.

Structured substrate hydrogel

Built into the growing substrate. Designed for
routine moisture management between
irrigation events — holding water where roots
can use it and releasing it as the substrate
dries — with establishment and nutrient
functions as the product develops.

Both share one design principle: they are built on the same biodegradable polyaminoacid core, do their work for the life of the crop cycle, and leave no persistent polymer behind in the substrate or the soil. And both are designed to combine into an integrated root-zone system delivered through substrate and protocol.
The problem
In substrate-grown crops, the root zone dries back
between irrigation events. Growers manage this
with irrigation frequency, substrate choice and
additives, each with a cost in water, nutrients,
labour or consistency. Existing water-management
polymers were not designed for these systems and
many persist in the substrate after use.
OUR APPROACH
We are developing polyaminoacid products that hold water in the root zone and release it as the substrate dries.
Candidates are designed against the grower's requirements — moisture between irrigation events, compatibility with fertigation, no change to the production protocol — and tested against current practice, not against untreated controls alone.
WHERE IT APPLIES
Protected horticulture (glasshouse and
polytunnel crops)

Growing substrates and potting media (coir, peat-reduced mixes)

Soft fruit and other high-value substrate crops

Fertigation systems where moisture and
nutrient stability interact
WHAT WE MEASURE
Moisture availability between irrigation events

Water-use efficiency under variable conditions

Crop establishment and consistency
across the cycle

Compatibility with substrates,
fertigation and the existing protocol
Development programme

Performance products, developed
with the experts who will test them.

Planet Smart's agriculture products are being developed in a structured programme with independent horticultural expertise. The programme establishes how candidate products perform against current grower practice — under defined substrate, irrigation and crop conditions — so that what reaches a grower has been proven in the system it will be used in.
