Seedling Tray 5x5 cm (90 Units) – Biodegradable Propagation System

The Seedling Tray 5x5 cm (90 Units) is the professional launchpad your crop deserves, designed to guarantee a high survival rate during the most critical phase of cultivation: germination and the first transplant. This biodegradable system allows you to start up to 90 plants simultaneously, ensuring that the root system develops in an aerated environment and completely eliminating the risk of damage when moving them to their final home.

Do you know why so many crops fail before they even really start? It is usually due to poor root management during the first few weeks. Many growers use plastic cups, heavy substrates, or containers that suffocate the roots, causing them to spiral and strangle themselves.

This mistake has a price: stunted plants, stress that delays growth by weeks, and in the worst cases, the death of the seedling due to shock during transplanting. If you treat the roots badly from day one, you are limiting the potential of your harvest before you even turn on the lights.

The solution is to work with nature, not against it. With this biodegradable tray, the roots breathe, prune themselves naturally upon contact with the air, and best of all: you don't have to remove the plant from the pot. You simply plant the entire block into the Soil For Cannabis, avoiding any stress and ensuring explosive growth from the very first minute.

Typical myths about biodegradable trays

• Myth: "Plastic pots are better because they retain more water." Reality: Excess retention is the enemy of young roots. These fiber trays maintain the perfect balance of humidity and oxygenation to prevent rot.
• Myth: "Biodegradable pots break down before I can transplant." Reality: They are designed with wood fiber and lime to maintain their consistency perfectly during the seedling phase (2-4 weeks) without falling apart.
• Myth: "Roots can't get through the wall." Reality: Quite the opposite. The porous material allows roots to penetrate easily, facilitating immediate integration with the new substrate.
• Myth: "They are only for seeds." Reality: They are also excellent for Cloning, as cuttings need maximum aeration to root quickly.

What this product really does (and what it doesn’t)

The Seedling Tray 5x5 cm acts as a temporary, high-performance home for your plants. Its main function is to promote "air pruning". When a root reaches the wall of a plastic pot, it hits a barrier and starts to circle (spiral). In this tray, the root penetrates the porous wall, comes into contact with the air, and stops growing at the tip, stimulating the plant to generate more secondary roots from the stem. The result is a dense and healthy root ball, ready to explode when transplanted.

However, you must understand that this is a transition product. It is not designed to grow a plant for months. It is a tool for the first stage of life (germination and first vegetative weeks). Once the roots start to protrude visibly through the walls, it is the signal that they are asking for more space.

Advantages and benefits when used properly

• Zero Transplant Shock: By planting the pot directly into the ground or a larger pot, the plant never suffers root exposure. Growth does not stop.
• Superior Oxygenation: Unlike plastic, wood fiber allows the substrate to breathe, drastically reducing the risk of fungi like Pythium.
• Optimization of Space: You can manage 90 plants in a very small space, ideal for selecting the best phenotypes or for SOG (Sea of Green) crops.
• Ecological and Sustainable: You reduce the use of single-use plastics. The tray decomposes and becomes organic matter in the substrate.
• Perfect pH Balance: The addition of lime in its composition helps to buffer the pH, creating a friendly environment for the roots.
• Versatility: Compatible with Grow Trays and heated propagators to maintain the ideal temperature.

Tips to choose well according to your expectations

If you are a grower looking for speed and quantity, this tray is your best ally. It allows you to process a large volume of seeds or cuttings with minimal effort during transplanting. It is perfect for those who want to set up a uniform crop where all plants start with the same advantage.

• If you expect to keep the plants in these pots for more than a month, this is not the product (look for rigid pots).
• If you are looking to avoid root cleaning and want a "Plug & Play" transplant, this is exactly what you need.
• Remember to keep the trays moist (but not soaked), as fiber dries out faster than plastic.

Frequently Asked Questions

Do I really have to plant the pot with the plant?

Yes, that is the main grace of the product. The roots will grow through the biodegradable material effortlessly. Removing the plant would be counterproductive and you could damage the root ball.

How long does it take to degrade?

Once buried in the damp substrate, the decomposition process accelerates. In a few weeks, it will be part of the soil, although the roots will have passed through it long before.

Can I cut the tray?

Totally. Although it comes in a block of 90 cells, you can cut it with scissors to separate individual groups or units if you don't need to germinate so many seeds at once.

Is it compatible with hydroponics?

It is ideal for soil and coco coir. For strict hydroponic systems (like DWC or NFT), it is better to use net pots with clay pebbles or rockwool, as the fiber could release sediment into the tank.

Personal Experience of Pevgrow’s CEO (Alan)

I've seen too many promising crops ruined in the first week by clumsy hands during transplanting. There is nothing more frustrating than seeing a seedling wither because you broke a main root trying to get it out of a yogurt cup. When I started using these biodegradable trays, that problem disappeared overnight.

In my experience, the difference in growth speed is noticeable. The plants don't suffer that 2 or 3-day "stop" after transplanting; they just keep growing. If you are serious about your genetics, don't skimp on the first home for your plants. These trays are cheap, effective, and save you headaches.
