CANNA Spanner Nutrient Bottle Cap Opener Tool

Get Stuck Caps Off Without Wrecking the Lid

The CANNA Spanner is a tough plastic tool for growers running the larger 5 and 10 litre CANNA nutrient containers. Anyone who feeds a room from big containers knows the problem: caps seize solid after a few feeds of dried nutrient in the threads, and breaking the factory seal on a fresh one with wet hands is worse again. Both usually end with a screwdriver, a damaged cap and nutrient down the side of the reservoir. The spanner fits over the ridges on the cap and gives you the extra leverage to turn it cleanly, first time, without deforming the lid or losing your grip.

Key Benefits

• Fits the ridges on 5 and 10 litre CANNA caps for a positive, non-slip grip
• Extra leverage to free caps that have seized with dried nutrient
• Breaks the seal on a new container without tools that damage the cap
• Tough plastic construction that will not corrode in a damp grow room
• Protects the cap and thread, so the container stays sealed between feeds
• Keeps mixing tidy and avoids spills when handling full containers

How to Use

• Dry the cap and wipe away any crusted nutrient from the ridges
• Seat the spanner squarely over the cap so the ridges engage all the way round
• Turn anti-clockwise with steady pressure rather than a sharp jerk
• Hold the container against a bench or the floor when working on a full 10 litre
• Rinse and dry the spanner after use so nutrient residue does not build up on it
