Cork Test Tube Holder | 9 Holes | 9x9x3cm - Propagation & Desk Stand

Root a row of cuttings on a windowsill without buying a shelf for them. This is a solid cork block, 9x9x3cm (3.5x3.5x1.2 inch), drilled with 9 holes so test tubes stand upright and level, and the cork grips a desk instead of sliding about. Test tubes are not included.

Specifications

Perfect for

• Propagating pothos, money plant and herb cuttings
• Single stems as a small table centrepiece
• Holding brushes, dotting tools or pens upright
• School and college science displays
• A windowsill row of rooting jars in one footprint

Compatibility

Works with: glass test tubes that fit the drilled holes.

Pairs well with: glass bottles and corks from the same shelf for a matching propagation set.

Not suitable for: heavy pots, tall vases or standing in water. It is a light cork block, not a weighted base.

How to Use

1. Check one test tube against a hole before you fill anything.
2. Slide each tube in until it seats and stands level.
3. Fill with water to just below the neck and add one cutting per tube.
4. Change the water every three or four days so the roots stay clean.

Frequently Asked Questions

Are test tubes included with the holder?
No. You get one cork block, 9x9x3cm, with 9 drilled holes. Tubes are sold separately.

Which test tubes will fit?
We state no hole diameter for this block, so measure the outside of your tube and ask us before ordering. A tube that is too narrow will lean rather than stand straight.

Will water damage the cork?
Cork copes with splashes, but do not stand it in water. Wipe spills rather than leaving them to soak in.

Should I pick this block or a single glass bottle for propagation?
Pick the block for a row of cuttings: it holds 9 tubes in one 9x9x3cm footprint. Pick a glass bottle with a cork when you want one stem on its own, since a bottle needs no stand.
