A deep blue-card supply for plant shelves

Catchmaster GRO Blue Regular Double Sided Sticky Traps come as a 72 pack for active growing spaces. The blue cards can sit near flowers, herbs, greenhouse benches, indoor plant shelves, hydroponic racks, and container groups.

The color gives a clear check point during a plant walk. A gardener can look at the card face, lift nearby leaves, and write a short note before moving to the next plant group.

Double-sided cards fit open benches

The double-sided format suits open shelves and greenhouse rows. A card can face a plant group from both sides, which keeps the monitoring point visible as the gardener walks past the bench.

The 72 pack also supports seasonal refreshes. Store clean cards in a dry place near labels, gloves, and plant notes so replacements are easy to grab.
