ORIGIN TRAY 75 X 75

Description

Origin Tray 75 x 75 is a compact propagation tray designed to support 75mm growing cubes, pots, or plugs in a clean, contained format for seedling development, clone rooting, and early plant establishment. We have been recommending quality propagation trays and growing equipment to UK growers since 2017, and having the right size tray for your propagation medium is the kind of practical detail that makes the difference between a clean, efficient propagation workflow and a chaotic one where plugs tip over and rooting media dries out unevenly.

How the Origin Tray 75 x 75 Supports Better Propagation Results

Propagation trays serve multiple practical functions beyond simply holding growing media in place. They create a contained, manageable unit that can be moved as a complete group for watering, inspection, or transfer to the growing environment, reducing the handling of individual plugs or cubes that can disturb developing roots. The tray base collects capillary moisture, maintaining humidity around the base of plugs and supporting even, consistent moisture distribution across all positions in the tray — preventing the dry-out of corner and edge positions that occurs in trays without adequate moisture-retaining structure. The 75 x 75 format is specifically matched to 75mm growing cubes — a size widely used for cuttings and seedlings that are being prepared for transplant into larger containers — providing a snug fit that holds each cube securely without toppling while still allowing easy individual removal at transplant time.

How to Use the Origin Tray 75 x 75

Place pre-soaked growing cubes or plugs into the tray positions. Sow seeds or insert pre-treated cuttings as appropriate. Add a small amount of water to the base of the tray to maintain humidity at substrate base level — this capillary moisture supports even hydration of the cubes without the need for top-watering that can disturb small seedlings. Place under a propagation dome and appropriate lighting. Monitor moisture levels and replenish water at the tray base as needed. At transplant time, remove individual cubes carefully, ensuring the developing root system is not disturbed. Clean the tray between uses with dilute hydrogen peroxide solution.
