The Flexi Tray High 120 x 120 x 10 cm is made of fully flexible rubber that adapts to narrow hallways and small doorways because it allows you to enter the room with the tray completely rolled up .

The 120 x 120 cm square perimeter offers a generous surface for organizing rigid, textile or Air-Pot pots , along with indoor accessories such as risers, collectors, mesh and measuring devices.

The inner skin is non-porous and 100% waterproof , a detail that simplifies cleaning: a sponge and mild detergent are all that's needed to remove traces of salts, limescale or fertilizer.
The elastic material provides stability on surfaces with small irregularities and dampens vibrations during transplanting tasks.

In 120cm grow tents, the Flexi Tray High 120 x 120 x 10cm creates a secure perimeter that retains drainage, protects flooring, and limits ambient humidity. Its 10cm height prevents spills during intensive watering, pruning, or cleaning, providing a tidy and easy-to-maintain environment for cannabis plants under LED or HPS lights.
It serves to collect drainage and function as a self-contained workstation. The 10 cm rim allows for reliable leachate sampling to adjust EC and pH , improving nutrient control in indoor cultivation . It also facilitates organization during transplanting, substrate mixing, and tool cleaning without splashing outside the work area.
Broad compatibility with textile containers, rigid plastics, and Air-Pots in 3x3 or 4x4 configurations depending on root volume. The square shape makes better use of space than rectangular trays and integrates with risers to promote ventilation under the pot and direct drainage to collection points. A key component in indoor growing accessories for projects that prioritize hygiene, safety, and water efficiency.
