Capsicum and Bell Pepper Grow Bag Manufacturer in India

Coco substrate for bell pepper and capsicum

Bell pepper is a long-cycle crop with a slower early growth rate than tomato or cucumber, so the substrate has to be forgiving at both ends of the season. We blend, compress, fill and pack to your gutter layout at our own facility in Tamil Nadu.

Substrate requirements

A long crop that is slow to establish and easy to overwater early

In the first weeks the plant is drawing relatively little water, so a substrate that holds a large buffer can stay wet for too long and set the root system back for the whole season.

  • Air-filled porosity 21.0 % The 50:50 blend. The higher air fraction protects the crop during slow early establishment.
  • Water buffering 5.66 L/kg Enough left for the peak demand period later in the cycle.
  • Early growth rate Slower than tomato Little water is drawn in the first weeks, which is when a retentive slab does the damage.
  • Late water demand Climbs sharply The position reverses later, so the substrate has to work at both ends.

Later in the cycle the position reverses and water demand climbs sharply. A pepper substrate therefore has to be forgiving at both ends, which in practice usually means favouring air over buffer and steering with irrigation frequency instead.

Reference blends

Which coco blend suits capsicum and bell pepper

Three of the five reference blends are relevant to long-cycle bell pepper.

  • Usual starting point

    50 : 50

    5.66 L/kg
    Air-filled porosity

    • WaterLess buffer
    • AirMore air

    Our usual recommendation for long-cycle bell pepper. The higher air fraction protects the crop during slow early establishment without limiting it later.

    Suits cooler climates and growers with tight irrigation control who want more buffer through the peak demand period.

These are starting points from measured properties, not prescriptions. Tell us your climate, irrigation frequency and target drain percentage and we will suggest a ratio — including a custom one, since we blend to order.

Blending and packing are done to your requirement. Ratios, particle grade, compressed dimensions, hole configuration, film and print are all made to order. Tell us what your crop and your handling line need and we will produce to it.

EC figures use the 1:1.5 volume extract method.

Root zone

What happens in the root zone

The same slab has to serve a crop that wants almost nothing in week three and a great deal in month six.

A section through the growing container: the fine pith fraction holding water low in the profile, the coarse chip fraction holding air above it, roots working through both, and free drainage at the base. The particle proportion shown is the 50 : 50 cocopeat to chip ratio.

50 : 50 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.
  1. 01 Establishment Low uptake. A large buffer stays wet too long and sets the root system back for the season.
  2. 02 Air Held in the coarse chip fraction, and what protects the crop through that period.
  3. 03 Peak demand Water demand climbs sharply later, so the buffer still has to be there.
  4. 04 Steering Favour air over buffer and steer with irrigation frequency instead.
  5. 05 Drainage Hole number, diameter and position decide how the base of the slab behaves.

Tell us your climate, irrigation frequency and target drain percentage, and the ratio follows from those three.

Capsicum substrate questions growers ask

A 50:50 cocopeat to chip blend at 21% air-filled porosity is our usual recommendation for long-cycle pepper. The higher air fraction protects the crop during slow early establishment without limiting it later.

Pepper has a slower early growth rate, so it draws relatively little water in the first weeks. A substrate holding a large buffer can stay wet too long and set the root system back for the whole season.

Yes. Compressed and expanded dimensions, planting hole count and spacing, and drainage hole position 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 with no chemical treatment. Calcium buffering is a separate chemical process available on request, and for a long-cycle pepper crop on automated fertigation it is usually worth it.
