Trials conducted with AgriNomix evaluated how to optimize flat-filler settings when using HydraFiber® mixes in small-celled containers. The work compared peat-, perlite-, coir- and HydraFiber-based substrates in 1006 and 804 cell packs, as well as 72 cell trays. Using a KVXL pot and flat filler equipped with a prototype agitator running at approximately 300 rpms, the team adjusted plow, compactor and drop settings to improve uniformity. Results showed that proper agitation and machine adjustments provided excellent fill with firm cells, strong tray coverage and effective performance through transplanting, while highlighting the importance of managing flow, moisture and transplanter depth.
Key Points
- Objective was to determine optimal equipment settings to uniformly and adequately fill small celled packs and minimize shrink when using HydraFiber mixes.
- Trials compared multiple mixes, including 80% Peat: 20% Perlite, 80% Peat: 20% HydraFiber 160WB, 70% Peat: 30% HydraFiber 160WB, and 65% Coir: 35% HydraFiber 065WB in 1006, 804 and 72 cell containers.
- Prototype agitator on a KVXL filler, set near 300 rpms with a 2–3″ media layer, plow high and compactor low, produced excellent fill with no voids and firm cells; KV98 fillers also performed well after adjusting drop and propeller.
- Additional considerations emphasized managing flow, maintaining correct moisture, using soil returns, propellers, and increasing transplanter depth settings for best results.
