Forest Seedling Tray with 54 cells, designed for demanding propagation stages in indoor cultivation . The 12 cm high cells facilitate seed germination and allow for the raising of seedlings with a larger substrate volume, keeping batches organized and ready for transplanting without stress from day one.

The 54-cell Forest Seedling Tray offers an optimized format for deep roots. Its rigid, lightweight plastic structure retains moderate heat and fits in technical tables and propagators.
Tray dimensions 50 x 32 x 12 cm and cells of 4.5 x 4 x 12 cm that allow the development of a straight taproot with vigorous lateral roots, forming a dense and stable root ball.
The perforated base accelerates drainage and oxygenation , minimizing waterlogging and reducing the likelihood of fungus during the critical rooting phase.
With 54 cells , the balance between capacity and individual control is excellent: sufficient density for continuous production and comfortable space for labeling by variety, date and batch.
It can be used with fine peat, coconut, perlite, cutting mixes or commercial plugs; the square geometry guides root growth downwards, preventing spiraling and facilitating clean transplants to pots, slabs or hydroponic systems.
In home and professional cannabis, aromatic and horticultural plant programs, this tool stands out among cheap indoor growing accessories for its performance, durability and integration with domes, heat mats and carrier trays available in any online grow shop .
For consistent results, it is advisable to maintain soft propagation lighting, periodic ventilation of the dome, and hygiene protocols between cycles.
The high-cell design allows for more stable and less frequent watering, useful in greenhouses where temperatures remain mild. Measuring 50 x 32 x 12 cm, it is compatible with standard propagators and provides a homogeneous microclimate for rapid root development. The perforated base distributes excess water, promotes aeration , and prevents damp patches. Convenient watering is achieved with a fine mist sprayer, and easy visual monitoring is provided by well-aligned rows for labeling and daily tracking.
It's ideal for germinating seeds , rooting cuttings, and keeping seedlings in seed trays longer thanks to its larger substrate volume . In indoor cultivation, it promotes a strong root system that reduces post-transplant stress and improves phenotypic uniformity. It's an excellent tool for continuous cannabis plant cycles, allowing for selection based on vigor, structure, and nutrient response from the very beginning.
The kit performs optimally with dedicated indoor growing accessories : a transparent dome with adjustable ventilation, a heating mat with a thermostat, a digital thermo-hygrometer, a fine mist sprayer, and a rigid carrying tray for damage-free transport. Recommended accessories for cuttings include rooting hormone and low-EC root stimulators. Waterproof labels and a permanent marker facilitate traceability by batch and date. The entire set helps maintain stable parameters and minimize losses due to mold or overwatering.
1) Prepare a light medium (peat/coconut with 20–30% perlite) or a compatible plug. 2) Moisten evenly to field moisture, avoiding compaction to preserve porosity. 3) Sowing: make a cavity, insert the seed at the appropriate depth, and cover lightly. 4) Cuttings: make a slanted cut, apply rooting hormone (optional), and insert firmly. 5) Place under a dome and ventilate intermittently; maintain gentle propagation light and a warm temperature. 6) Adjust watering according to the weight of the tray and the appearance of the substrate; at a height of 12 cm, precise and less frequent watering is sufficient. 7) When roots emerge from the base or the root ball has firmness, transplant to the final container (coconut, perlite, Hydroton , rockwool) with a settling watering. This workflow reduces stress and accelerates adaptation to the new medium.
The price per cavity is competitive compared to shallower seed trays when the goal is a higher quality root ball. Reuse is possible following cleaning and disinfection protocols, which increases profitability per season and fits with strategies for inexpensive indoor growing accessories .
