iHORT Q-Plug Cubes, bag of 100

Square Aerated Cubes for Stabilized Propagation, Bag of 100

An unstabilized propagation medium falls apart the moment it's inspected, moved, or run through automated equipment, which risks damaging tender clone and seedling roots before they've even established. iHORT Q-Plug's aerated, water-holding texture keeps its shape through handling while still holding enough moisture to start clones and seedlings reliably.

Each square cube measures 1.25 inch wide by 1.25 inch deep, shipped in bags of 100.

Key Features & Benefits

• Aerated, water-holding texture — supports clones and seedlings started in propagation trays.
• Transplant-ready — moves into soil, rockwool, coco, or other standard growing substrates without disturbing the root zone.
• Stabilized shape — holds together through inspection, moving, or automated handling without falling apart.
• Balanced air porosity and water control — supports stronger root development than a loosely packed medium.

Who Should Use These Cubes

Commercial growers and home gardeners propagating clones or seedlings who want a stabilized, transplant-ready growing cube.

Frequently Asked Questions

What does the aerated texture do?

It holds water while supporting clones and seedlings started in propagation trays, without collapsing or falling apart during handling. That stability is what allows trays to be inspected or moved without disturbing young roots.

Can these be transplanted?

Yes, into soil, rockwool, coco, or other standard growing substrates once roots have established in the cube. The cube's shape holds together through that transition instead of crumbling apart.

How many come in a bag?

This square option ships in bags of 100. That count works well for flats sized to match standard propagation trays.

How do I know when a cube is ready to transplant?

Look for visible root growth reaching the outer edges of the cube before moving it. Transplanting too early risks disturbing roots that haven't yet established enough to hold the cube's shape on their own.
