Plants change shape through a nursery life: a seedling wants a small root zone, a liner wants room to run, and a finished specimen wants volume and stability. This container range follows the whole arc. The studded wall keeps pruning root tips at every stage, so the root ball stays fibrous as the plant moves up the sizes, and the same wall system runs from starter rounds to large tree containers. Diameters span 15 to 200 cm in PE or PVC, with base plates from 15 to 60 cm and samples for stage tests.
Stock passes through several homes before it leaves a nursery, and every up-sizing is a chance for roots to stall. This container range is built so the same system carries a plant from its first round to its final tree container, through every size step between.
Seedling and liner blocks start in small rounds, grow-on blocks take the mid formats, and finishing stock moves into the large containers without the programme swapping brands or methods between steps. Handlers keep one routine, pots re-order in the sizes a season actually used, and stock that jumps a step is simply moved up the same wall system. The range is covered in the air pruning pot range.
Young roots respond to air fastest, which is why the first pot matters most: tips stop at the openings and branch early, and the habit carries into every later size. On the way up, the lifted root ball moves whole from one container to the next, settles into the new volume, and starts working the studded wall again rather than uncoiling from a compressed core. That continuity is what keeps growth even through a season of repotting.

A programme can stage its orders the way it stages its crop: starter rounds for the propagation window, mid sizes for the growing-out months, and large formats ahead of sale season, all from the same wall system and the same base plates. Big formats for tree work sit in the tree and nursery container range, and plates stay interchangeable as stock moves up.
Samples make the stage plan concrete: a buyer tests one size at each step before the season starts. Colours run from standard black to matched finishes, sizes and plates mix in one load, and packing ships in woven bag or carton. Flexible soft containers for the same programmes sit in the planting bag range. Trade coverage of growing practice runs at HortiDaily and FreshPlaza.
What size suits a seedling or liner stage?
Small rounds hold seedling and liner blocks, with the mid formats taking grow-on stock once roots have filled the first pot.
Does up-sizing disturb the roots?
The root ball lifts whole and moves into the next size, and because it is fibrous rather than coiled, it settles into the new volume without stalling.
Can a programme order stage by stage?
Yes. Sizes and plates mix in one load or arrive as staged shipments, with samples for each step and colours matched across orders.
Tell us the stages your crop passes through and the volumes at each one, and we will come back with the size plan and lead time.
