Black square pot 1 Liter 13 x 13 x 13 cm. is a compact black plastic container with a raised bottom and drainage holes that promote oxygenated roots. Ideal for seedlings, cuttings, and initial stages in indoor cultivation, it optimizes space and facilitates precise watering without waterlogging.

This square pot in a compact format stands out for its dimensions 13 x 13 x 13 cm and 1 liter capacity, measurements designed for nursery, rooting, and early growth of cannabis plants and other species.
The raised bottom creates an air chamber under the substrate that speeds up drainage through the bottom holes, keeping the root zone aerated and stable.
The black plastic body limits light passing to the substrate, reducing algae and preserving beneficial microbiology.
The square format allows a greater number of units per tray, improving density per square meter in grow tents and indoor cultivation facilities.
Excellent tool for staggered management: germination or cuttings in 0.2–0.5 L, transplant to Black square pot 1 Liter 13 x 13 x 13 cm. and, when the root ball colonizes, move to 3–7 L without slowing vigor.
At Hydroponics Blanes, online grow shop and trusted Grow Shop, it is included in kits with aerated substrates (peat, coco, perlite), saucers, and drip systems.
Prepared for intensive cycles, it reduces losses due to overwatering and simplifies the organization of tables, shelves, and indoor accessories, with convenient logistics and discreet shipping throughout Spain.
In indoor cultivation, the reduced footprint favors high-density layouts under LED or HPS, maximizing useful light per plant. The 13 cm substrate column is evenly hydrated, ideal for frequent and controlled watering schedules. The square design fits standard trays, facilitates clean drainage, and speeds up maintenance tasks in technical spaces.
It is used for nursery stages, rooting cuttings, germination, and early growth in cannabis cultivation. The 1 L volume promotes the formation of a compact root ball, ready for successive transplants without stress. It is also practical for short-cycle varieties or aromatic microcultures that require fine control of watering and nutrition.
It is advisable to combine with compatible saucers or growing trays, labels, soft rings, guiding meshes, light stakes, and drip irrigation lines with low-flow drippers. In indoor cultivation facilities, the perforated base quickly drains excess, improving oxygenation and avoiding saturated areas. Accessories such as pH/EC meters, fine sprayers, and aerated substrates reinforce professional seedling management.
1) Preparation: Place 0.5–1 cm of expanded clay or coarse perlite to enhance drainage. Fill with an aerated mix (peat/coco + perlite) and moisten evenly.
2) Sowing/Cutting: Make a small hole, insert seed or rooted cutting and cover with substrate without over-compacting. Keep stable humidity and good ventilation.
3) Watering: Apply water or nutrient solution until slight runoff is observed through the bottom holes. Adjust frequency according to temperature, plant size, and stage.
4) Organization: Arrange in a grid inside trays to move complete groups. Rotate 90° periodically to even out light exposure.
5) Transplant: Move to 3–7 L when roots appear at the perimeter. Water moderately after the change to stabilize the root ball.
