The Canna Spanner is a handy tool for growers using five and ten-litre nutrient bottles. Great for helping to release stuck bottle caps or break the seal on a brand new bottle.
How the Canna Spanner Works
The Canna Spanner is a rigid plastic spanner that fits over the ridges on the five and ten-litre Canna nutrient bottle caps. Once fitted over, the Canna Spanner will give you extra leverage to get those stuck bottle caps off.
