Strawberry Coco Substrate Manufacturer in India
Coco slabs for tabletop and trough strawberry
Elevated tabletop strawberry gives each plant a very small volume of substrate to live in, so the buffer is short and the wash matters as much as the blend. We blend, compress and pack to your trough layout at our own facility in Tamil Nadu.
Substrate requirements
A small root volume that cannot be allowed to dry
Elevated tabletop strawberry gives each plant a very small volume of substrate to live in. That changes the priorities completely compared with a tomato slab: the buffer is short, so water holding capacity and re-wettability matter more than raw drainage.
- Water buffering 7.32 L/kg Straight cocopeat holds the most water in our range, which is what a short buffer needs.
- Air-filled porosity 5.2 – 10.2 % The retentive end of the published range. Here re-wettability matters more than raw drainage.
- Salt sensitivity Among the highest Sodium and potassium a tomato crop would tolerate can suppress a strawberry crop.
- Uneven drying Shows in days A substrate that dries unevenly shows up as uneven fruit within days rather than weeks.
Strawberry is also among the more salt-sensitive crops grown on coco. Residual sodium and potassium that a tomato crop would tolerate can suppress a strawberry crop, which is why the wash matters as much as the blend.
Reference blends
Which coco blend suits strawberry
Two of the five reference blends are relevant to tabletop and trough strawberry.
-
Usual starting point
100 : 0
Straight cocopeat
- Water holding capacity
- 7.32 L/kg
- Air-filled porosity
- 5.2 %
- WaterHolds the most water
- AirLeast air
The usual starting point for tabletop strawberry. The high retention is an advantage where the root volume per plant is small and irrigation is frequent and short.
-
80 : 20
Cocopeat to chip
- Water holding capacity
- 6.73 L/kg
- Air-filled porosity
- 10.2 %
- WaterRetentive base
- AirEnough chip to keep air moving
The better choice in warmer climates, in longer troughs, or wherever the base of the slab has previously stayed too wet. The chip fraction opens the profile without giving up much buffer.
Low EC matters more here than the blend does. We supply washed low-EC material for strawberry as standard, and we can supply buffered material where your programme calls for it.
These are starting points from measured properties, not prescriptions. Tell us your trough or tabletop volume per plant, your irrigation frequency and your climate, and we will suggest a ratio — including one that is not on our standard list, since we blend to order.
EC figures use the 1:1.5 volume extract method.
Root zone
What happens in a shallow trough
The smaller the volume per plant, the less margin there is between one irrigation and the next. Everything below follows from that.
100 : 0 cocopeat to chip — the blend this page leads with, drawn in proportion
- Fine pith fraction Holds the water. Deeper in the profile as the fine fraction rises.
- Coarse chip fraction Holds the air. The pore space between the flakes is what keeps the profile open.
- Root zone and drainage Roots work through both fractions; what the profile cannot hold leaves at the base.
- 01 Root volume Very small per plant on an elevated tabletop, which shortens every buffer the substrate can offer.
- 02 Water holding Matters more than raw drainage, because there is no reserve to fall back on.
- 03 Re-wettability Uneven drying shows up as uneven fruit within days rather than weeks.
- 04 Residual salt Strawberry is among the more salt-sensitive crops grown on coco, so the wash matters as much as the blend.
- 05 Trough length Longer troughs favour a little more chip, because the base of the run stays wetter.
Tell us your trough or tabletop volume per plant, your irrigation frequency and your climate, and the ratio follows from those three.
Made to order
Custom strawberry slabs for your trough system
Strawberry systems vary more than almost any other protected crop, so almost nothing about our slabs is fixed. All of the following are produced to order.
- Blend ratio Any proportion, not only our standard steps.
- Particle grade Fine, medium or coarse pith.
- Compressed and expanded dimensions Cut to fit your trough or tabletop.
- Planting holes Count and spacing for your plant density.
- Drainage holes Position and diameter, which decide how the base of the slab behaves.
- Film colour To your specification.
- Print Plain, or your own artwork.
The substrate in service
Coco substrate filling a tabletop trough: a shallow, even profile with the plant spacing set by the trough layout rather than by the slab.
- Blend ratio Any proportion, not only our standard steps.
- Particle grade Fine, medium or coarse pith.
- Compressed and expanded dimensions Cut to fit your trough or tabletop.

Straight 100% cocopeat is the usual starting point at 7.32 L per kg water holding capacity, because the root volume per plant is small and irrigation is frequent and short. An 80:20 blend suits warmer climates or longer troughs.
Strawberry is among the more salt-sensitive crops grown on coco. Residual sodium and potassium that a tomato crop would tolerate can suppress a strawberry crop, which is why the wash matters as much as the blend.
Yes. Compressed and expanded dimensions, planting hole count and spacing, drainage hole position, film colour and print are all made to order.
The 1:1.5 volume extract method. If your specification uses saturated media extract, tell us and we will supply the equivalent figure. The two differ by roughly a factor of two.
Our standard product is unbuffered, washed with water alone to below 0.5 mS/cm. That matters for strawberry, because low EC here is achieved naturally rather than by chemical treatment. Calcium buffering is a separate chemical process available on request. Tell us your fertigation approach and we will advise which is right.
