Black/gray square pot 0.23 Liters for germination, cuttings, and vigorous start in indoor cultivation. Compact format 7 x 7 x 8 cm, 100% recycled plastic with raised bottom for optimal drainage and internal ribs that prevent root circling. Ideal for work tables and multipurpose trays.

This Black/Grey Square Pot 0.23 Liters is designed for the initial stages of cannabis plants where every millimeter counts. The square format increases tray density, facilitates straight lines, and improves ergonomics in indoor grow setups.
The base with a raised bottom creates an air chamber that speeds up water drainage, keeping the root ball moist without waterlogging. The interior features anti-spiral grooves, guiding roots downward and sideways for a more fibrous and efficient root mass.
The bottom drainage holes stabilize the frequent watering typical of rooting, reducing the risk of rot. Capacity of 0.23 L offers a balance between moisture and oxygenation, perfect for light peat substrates, coco, or airy mixes with perlite.
Made from 100% recycled plastic, durable, washable, and reusable, compatible with gentle disinfection. The black/grey color limits light entry to the substrate, protecting roots and beneficial microbiota.
Works with manual watering or low-flow rings/drippers and fits standard propagation trays.
A precise tool for cycles with careful fertilization, pH and EC control, and short watering intervals.
Dimensions 7 x 7 x 8 cm optimized for tents, grow tables, and propagators. The square design maximizes plants per square meter during the starting phase, leaving clean and accessible aisles. The combination of raised bottom and grooved walls promotes root oxygenation, an essential base for stress-free transplants and uniform growth in cannabis cultivation.
It is used for germinating seeds, rooting cuttings, and carrying out the first weeks of vegetative growth with humidity control. The contained volume speeds up drying between waterings, stimulating fine, white roots that assimilate nutrients more efficiently. Perfect as an initial step before moving to 1–3 L or directly to larger formats, maintaining growth rhythm and minimizing wasted substrate.
Fits with propagation trays, jiffys or rockwool cubes as a pre-base, tags for traceability, mini-stakes, fine sprayers, and thermo-hygrometers to control the environment. With a set of drippers or graduated pipettes, watering becomes precise to the millimeter. Adding perlite or coco fiber improves aeration; a thin layer of expanded clay helps stabilize drainage on tables. All available at Hydroponics Blanes, a catalog of indoor accessories ready to complement any workflow.
1) Preparation: fill with airy substrate and moisten until field capacity is reached without excess. Check that the raised bottom sits correctly on the tray.
2) Sowing/Cutting: make a 1–1.5 cm hole, place the seed or already treated cutting, cover gently, and mist the surface.
3) Watering: water with low conductivity, aiming for 5–10% drainage to avoid salt buildup. Adjust frequency according to the weight of the pot and evaporation rate.
4) Environment: maintain moderate VPD and gentle ventilation; a light airflow strengthens stems without dehydrating the root ball.
5) Transplant: when roots emerge through the holes or the root ball becomes firm, transplant to a larger volume to continue root expansion without breakage.
