  2. Compare the contents

    Cell-tray sets include the cell tray and base tray. Propagation sets add a capillary mat; propagators add a cover. Check the exact contents for the selected model.

  3. Assemble matching parts

    Use the base suited to the STP model and fit the mat according to the product instructions. Then prepare and fill the cell tray.

Good to know

Which system includes the STW propagation houses?

STW-40, STW-77 and STW-150 belong to the G24 system with a 53 × 31 cm base format. STP is a separate system. Replacement parts must match the specific version.

What is the difference between a set and a propagator?

STP offers configurations with a base tray, with an additional capillary mat and with an additional cover. The comparison cards show the contents of each option; the cell tray and accessories must match.

Which dimensions apply to QP 273-2?

The original dimensioned drawing specifies 322 × 522 mm for the cell tray. Compatibility with the assigned STP accessories is confirmed. A system name does not mean that every component has identical outer dimensions.

Do G24 covers fit STP?

G24 and STP have different base dimensions. Use covers, watering trays and base trays explicitly assigned to the STP system.
