Propagation
Seedling Trays
Rigid plug trays in thirteen standard configurations, from 35 to 104 cavities. Engineered for uniform germination, clean extraction and multi-season service.
Overview
The tray decides the transplant
A seedling tray looks like a commodity. It isn't. Cavity volume sets root mass, taper sets extraction cleanliness, and drainage geometry sets whether your crop damps off in week two.
GreenLeap plug trays are moulded from rigid high impact polystyrene (HIPS) with a consistent wall section, so a filled tray holds its shape through mechanical filling, watering and handling. Cavities are tapered and bottom-drained: the plug lifts as an intact root ball, and excess water leaves before it stalls the root zone.
We stock thirteen standard configurations across square, round and cup formats. The range covers everything from high-density leafy propagation at 104 cavities down to 8-cup trays for grafted and large-format stock. Where a nursery runs automated seeding, tray footprint and cavity pitch stay consistent batch to batch — the constraint most operators actually care about.
The practical decision is almost always the same trade-off: more cavities means more plugs per square metre but less media per plug. We help you land that against crop, holding period and your bench space — not against what's cheapest per tray.
Features
Built for the nursery floor
Consistent cavity pitch
Dimensional repeatability batch to batch, so vacuum seeders and tray fillers stay calibrated.
Tapered draft angle
Plugs release intact without flexing the tray — the single biggest driver of tray service life.
Bottom drainage
Each cavity drains rather than perching water, cutting damping-off risk in humid Eastern India conditions.
UV-stabilised HIPS
Resists embrittlement under Indian sun exposure across repeated outdoor cycles.
Nestable & stackable
Compact stack height cuts freight cost per tray and keeps storage footprint down between cycles.
Sanitation-tolerant
Withstands standard hypochlorite and quaternary sanitation between cycles without surface crazing.

Advantages
What changes when the tray is right
The gains from a correctly specified tray are not marginal. They compound across the cycle — germination uniformity feeds transplant uniformity, which feeds harvest uniformity and grading yield.
- Uniform germination. Equal media volume per cavity means equal moisture and equal emergence timing — no straggler plugs holding up the whole tray.
- Intact root balls. Correct taper means the plug lifts whole. Root damage at extraction is transplant shock you pay for two weeks later.
- Lower damping-off. Bottom drainage prevents the perched water table that fungal pathogens need.
- Media economy. Right-sized cavities stop you buying cocopeat you don't need — a real line item at 200,000 plugs a cycle.
- Multi-cycle life. Rigid HIPS survives repeated wash-and-sanitise cycles, so cost per use falls sharply after season one.
- Machine compatibility. Stable footprint keeps automated lines running without per-batch recalibration.

FAQ
Common questions
Cavity count is a trade-off between plug volume and trays per square metre. Higher counts — 98, 104 — give more plugs per tray with less media per cell, suiting fast crops like tomato, chilli, brinjal and most leafy vegetables. Lower counts — 35, 38, 50 — give larger root volume for cucurbits, papaya, grafted stock and anything held longer before transplanting. The rule of thumb: if a seedling will sit in the tray beyond roughly four weeks, move to a lower cavity count.
Our HIPS trays are built for multiple cycles, but real service life depends on handling and sanitation rather than the plastic itself. Nurseries that wash, sanitise and store trays flat under cover typically get several seasons. Trays stacked in direct sun between cycles, or flexed hard during extraction, fail earlier regardless of grade. If your extraction crew is bending trays to pop plugs, the cavity taper is wrong for your media — that's worth fixing before buying replacements.
Square cavities hold more media volume in the same footprint and give better root distribution into the corners, which suits most vegetable propagation. Round cavities release the plug more cleanly and are preferred where extraction speed is the bottleneck or where the growing medium is loose. For most commercial vegetable nurseries in India, square is the default; round gets specified when extraction throughput is the constraint.
Yes. Standard tray footprints and consistent cavity pitch allow use with vacuum seeders, tray fillers and de-stackers. If you're running a specific machine, share the make and model with your enquiry and we'll confirm dimensional compatibility before dispatch rather than after.
Buffered, low-EC cocopeat is the standard medium for plug production, often blended with perlite or vermiculite at higher cavity counts where drainage matters more. We supply matched cocopeat blocks and discs, and can specify the blend against your cavity size and crop in the same quote.
