DaPlug Sponge Cubes Bulk - 50 Count Bag

Moisture-Holding Starter Plugs for Seeds and Clones - 50 Count

Seedlings and cuttings struggle when their starting medium stays too wet or dries unevenly. These all-natural sponge cubes hold moisture while keeping air in the medium, which supports even dry downs and steady root development. You can plant the cube directly into soil or a hydroponic system when the roots are ready.

This bag of 50 suits growers who start batches of seeds or clones and want a ready-to-use medium without mixing or rinsing. It works for a hobby tray as well as a regular indoor propagation routine.

Key Features & Benefits

• All-natural sponge material — gives a soft, absorbent medium for seeds and cuttings.
• Soil and hydroponic compatible — move the cube straight into your growing setup without disturbing the roots.
• Contains Trichoderma — biocontrol organisms for non-sterile applications.
• Ready to use — pre-soak in a cloning or feeding solution before starting.
• 50 cubes per bag — enough to fill several propagation trays.

Who Should Use DaPlug Sponge Cubes

Home gardeners and commercial growers who start seeds or take cuttings for soil or hydroponic cultivation will find these cubes useful. They suit anyone who wants to move from propagation to vegetative growth without a separate transplanting step.

Frequently Asked Questions

Q: Do I need to prepare the cubes before use?
A: The cubes are ready to use. For best results, pre-soak them in a cloning or feeding solution before placing seeds or cuttings.

Q: Can I use them in both soil and hydroponics?
A: Yes. The cubes are compatible with soil and hydroponic applications, so you can transplant the whole cube.

Q: What is Trichoderma?
A: Trichoderma is a group of biocontrol organisms. These cubes contain it for non-sterile applications.

Q: What if I see white or green growth on the cubes?
A: The Trichoderma in the cubes can show up as white, downy growth that later turns greenish. This is the beneficial organism rather than unwanted mold, and pre-soaking solution will dissipate it.

Q: Can I sterilize the cubes?
A: For sterile applications, boil the cubes before use or before reintroducing cloning or feeding solutions.

Q: How do I check moisture?
A: Squeeze a cube firmly to judge its moisture. Warm conditions dry the cubes faster, so keep them thoroughly hydrated.
