Black square pot 14 L. 28 x 28 x 28 cm. is a robust container made of 100% recycled plastic with a raised bottom and drainage holes, designed for precise watering and oxygenated roots in indoor cultivation. Square format that optimizes space and crop stability.

The Black square pot 14 L. 28 x 28 x 28 cm. combines generous volume with a manageable profile to organize dense grids in cabinets and technical rooms. The black plastic body limits light passage to the substrate, reducing algae and protecting beneficial microbiology.
The base incorporates a raised bottom that creates an air chamber; excess water circulates towards the lower holes, preventing waterlogging and promoting root respiration.
Inside, the anti-spiral grooves guide roots downward and sideways, forming compact and efficient root balls to absorb water and nutrients.
The 28 x 28 cm format provides stability for heavy canopies and facilitates periodic rotations under LED or HPS, homogenizing light exposure.
With a real capacity of 14 liters, it is ideal as a final container for medium and tall genetics in cannabis cultivation, or as an intermediate step before 18–25 L in projects that require greater root mass.
The square design fits standard trays, maximizes use per square meter and simplifies handling in indoor cultivation facilities.
Available at Hydroponics Blanes, online grow shop and trusted Grow Shop, with technical advice, a wide catalog of indoor accessories and discreet shipping throughout Spain.
The 28 x 28 x 28 cm format allows regular layouts on irrigation tables and trays, keeping work aisles clean. The 28 cm substrate column balances water retention and aeration, key in intensive cycles. The dark material protects the rhizosphere from direct light, essential in hot and high-intensity light environments.
It serves as a final container for medium/large cannabis plants, for vigorous growth and flowering with good water inertia. The 14 L volume provides enough water reserve without losing oxygenation, reducing the risk of rot. The interior grooves minimize spiraling, improving nutrient uptake and plant stability in advanced stages.
The most practical combination integrates cultivation trays or compatible collector plates (inside ≥ 28 x 28 cm), adjustable drippers of 2–4 L/h, SCROG meshes to open the canopy, stakes, soft rings and labels for traceability. pH and EC meters, along with aerated substrates (peat/coco with perlite), complete professional management in indoor cultivation and facilitate batch-to-batch consistency in indoor cultivation facilities.
1) Preparation: Add 1–2 cm of expanded clay or coarse perlite at the base to enhance drainage. Fill with aerated mix and moisten evenly.
2) Transplant: Center the root ball, gently compact to remove air pockets and keep the stem neck above the substrate line.
3) Watering and nutrition: Water until achieving 10–20% runoff through the lower holes. Adjust frequency according to stage, plant size, temperature and ventilation. Monitor pH/EC parameters at input and output.
4) Organization: Arrange in a grid inside trays to move complete groups; rotate 90° every few days to even out PPFD and vigor.
5) Maintenance: Between cycles, empty, wash and disinfect with a mild solution. Check that the raised base and perforations are free of obstructions.
