Our take on the Cultiwool 1.5" x 1.5" x 1.5" Cubes with Shrinkwrap

Cultiwool 1.5" stonewool cubes are small rockwool starter plugs for hydroponic propagation, sold here in shrink-wrapped strips totaling 2,250 pieces. The uniform, firm structure and fast-rooting stonewool suit fragile crops and cuttings that need a stable, airy medium. The best new price is $385.63 at Grow Wiser Garden Supply as of November 7, 2026, with two stores listing it new. That is a bulk case price, so compare it per cube against smaller packs before buying.

Questions and answers

Is $385.63 a good price for 2,250 Cultiwool cubes?
That works out to about 17 cents per cube, which is typical for bulk stonewool. Check smaller packs at per-cube rates to see if the case saves you money.
Do I need to soak these cubes before planting?
Yes. Stonewool is alkaline out of the bag, so soak cubes in pH-adjusted water before inserting cuttings or seeds.
What size cuttings fit a 1.5-inch cube?
These suit small cuttings, seedlings and fragile starts. Larger clones or rooted plants need bigger blocks or slabs.
Can I use these in any hydroponic system?
They fit net pots, trays and drip or ebb-and-flow setups. The cube just needs to stay moist but not waterlogged.
How should I store the unused strips?
Keep them dry and out of direct sun. Stonewool lasts a long time sealed, but damp storage invites mold.
Is stonewool safe to handle?
Wear gloves and a mask when separating cubes. The fibers can irritate skin and lungs, so handle it in a ventilated area.
