The TS-144 is a high-density seedling tray built for propagating large batches of vegetable seedlings efficiently. Whether you're filling a glasshouse bench or running a serious backyard propagation setup, the TS-144's 927-cell layout and root deflection technology help you grow more uniform, transplant-ready seedlings in the same space.
Root Deflection Technology — Why It Matters
The TS-144's standout feature is the root deflection fins built into the base of each cell. These fins redirect developing roots away from the cell walls and downward — preventing the curl that typically forms when roots reach a flat base. When you transplant, those correctly oriented roots advance rapidly into the surrounding soil. In testing, seedlings from finned cells showed measurably stronger root growth within 24 hours of transplanting compared to non-finned alternatives.
Large drainage holes keep the root zone well aerated and active throughout propagation, and the optimised cell depth-to-volume ratio supports even, uniform growth across every cell in the tray. At extraction, the design allows clean plug release with minimal stem or root damage.
What Makes It Different
- Root deflection fins — prevent root curl and stimulate faster establishment after transplant
- 927 cells per m² — grow more seedlings in less space without sacrificing quality
- Large drainage holes — well-aerated root zones for active, healthy growth
- Square, symmetrical format — easy to handle, stack, clean, and separate between batches
- Virgin HDPE with UV protection — durable through multiple growing seasons

Frequently Asked Questions
What vegetables work well in the TS-144?
The TS-144 suits most fast-cycling vegetable crops — brassicas, lettuce, herbs, Asian greens, and similar seedlings that are transplanted relatively young. The 26 cc cell volume is sized for seedlings that won't spend long in the tray before going into the garden or grow bed.
How do the root deflection fins actually help?
In a standard flat-bottomed cell, roots hit the base and start curling around — and that curl tends to persist after transplanting, slowing establishment. The TS-144's fins redirect roots downward before they can curl, so when the plug goes in the ground the root tips are already pointing in the right direction and start advancing into the soil immediately. The difference shows within 24 hours.
How do I clean and reuse the TS-144?
The square, symmetrical design makes the TS-144 easy to brush out, rinse, and stack between batches. The trays separate cleanly when stacked and the cell geometry doesn't trap media in hard-to-reach corners.
