White Square Pot 20 x 20 x 27 cm. 7 Liters is a 100% recycled plastic container, light color and raised bottom with drainage holes, designed for comfortable handling in indoor cultivation. The white tone reflects light and helps keep the substrate stable, promoting active roots from the start.

The White Square Pot 20 x 20 x 27 cm. 7 Liters offers a balance between compact size and useful volume for demanding species. The dimensions 20 x 20 x 27 cm allow efficient grids on trays and work tables, optimizing the square meter in cabinets and indoor growing facilities.
The white color reduces lateral heating against intense lights, while the raised bottom promotes rapid drainage towards the lower holes, preventing waterlogging.
The interior incorporates anti-spiral grooves that guide roots downward and sideways, achieving a homogeneous root ball with an excellent water/air ratio.
With a capacity of 7 liters, it is ideal as a final container for compact plants or as an intermediate step before 11–18 L in projects that require greater root mass.
The square geometry maximizes plant density per tray, facilitates measured watering, and keeps a clean organization under LED or HPS lights.
Perfect for cannabis cultivation and aromatics, it integrates with indoor accessories such as saucers, guiding nets, stakes, and drip systems.
Available at Hydroponics Blanes, online grow shop and trusted Grow Shop, with technical advice and discreet shipping for home and professional projects.
The light tone reflects part of the incident radiation, helping to maintain moderate substrate temperatures during long photoperiods. The 20 x 20 cm footprint facilitates regular layouts, improving PPFD uniformity and air circulation between canopies. The height of 27 cm creates a balanced substrate column for frequent watering with controlled drainage, a key condition in indoor cultivation of cannabis plants and compact varieties.
It is used for advanced rooting, growth and flowering of medium-sized genetics, maintenance of small mothers and aromatic microgardens. The 7 liter volume offers sufficient water reserve without losing aeration, reducing the risk of root rot. The interior grooves minimize spiraling, promoting white and young roots with better nutrient and water uptake, something essential in cannabis cultivation.
Recommended combination with growing trays and compatible saucers, adjustable drippers, stakes, SCROG nets, labels and soft rings. In indoor growing facilities with automatic irrigation, the raised base and drainage holes facilitate clean runoff and drainage measurement to control EC and pH. Aerated substrates (peat/coco with perlite) and reliable meters complete professional management batch by batch.
1) Preparation: Add 1–2 cm of expanded clay or coarse perlite to improve drainage. Fill with aerated mix and moisten evenly.
2) Transplanting/Sowing: Place the plant centered or seed at the appropriate depth. Gently compact to remove air pockets and keep the stem neck above the substrate line.
3) Watering and nutrition: Water until 10–20% runoff is obtained through the lower holes. Adjust frequency according to stage, plant size, temperature and ventilation. Check input and output pH and EC.
4) Organization: Arrange in a grid inside trays to move complete groups. Rotate 90° periodically to homogenize light exposure.
5) Maintenance: Between cycles, empty, wash and disinfect with a mild solution. Check perforations to ensure smooth water drainage.
