Balanced 5-3-7 formula with Magnesium
Unlike generic substrates, our urban garden mix is a technical product designed in Granada. With an NPK balance of 5-3-7 and an extra supply of Magnesium (Mg), we guarantee that your plants have the necessary energy for intense photosynthesis and explosive growth. This nutritional combination ensures greener leaves and stronger stems from the first week, reducing the reliance on external fertilizers.
Living structure with +40% organic matter
The secret to a productive vegetable garden lies in the soil structure. Thanks to its high concentration of organic matter (+40%) and enrichment with earthworm humus, this premium universal substrate maintains a spongy and airy texture over the long term. It prevents the compaction typical of low-quality soils, allowing roots to breathe and expand without resistance, which results in much healthier plants that are more resistant to stress.
Water retention and intelligent aeration
Our blend incorporates selected plant matter and coconut fiber to offer superior water management. This combination allows for optimal water retention—ideal for those who cannot water daily—without sacrificing drainage. The result is a perfect balance: constant moisture for the plant but with the necessary oxygenation to prevent root suffocation, both in indoor gardens and in full terrace sun.
Ready to use: from the bag to your garden bed
Designed to simplify your growing experience, this locally sourced (Granada) substrate comes ready to use. There is no need to mix components or amend the soil: it is the ideal vegetable garden soil for direct sowing, transplanting seedlings, and growing in containers of any size. Whether in raised beds, pots, or wooden planters, you provide your plants with the professional foundation they deserve for a successful, 100% organic harvest.
Frequently asked questions
How does this substrate differ from a common universal substrate?
How does this substrate differ from a common universal substrate?
Most universal substrates from large retailers are basic peat mixtures that compact over time. Our urban garden mix is a technical product from Granada with +40% organic matter and a 5-3-7 nutrient ratio. This ensures that the soil remains airy and feeds your plants in a balanced way, something that generic substrates cannot offer.
Do I need to add fertilizer or mix it with other soil?
Do I need to add fertilizer or mix it with other soil?
It is not necessary. This mix is ready to use from day one. Since it is enriched with worm castings and magnesium, it already contains the biological load and nutrients necessary for the seeding and transplanting phase. You just have to fill your container, dampen it slightly, and start growing.
What type of plants is this substrate ideal for?
What type of plants is this substrate ideal for?
Although it has been specifically formulated as vegetable garden soil (tomatoes, herbs, vegetables), its balance makes it a premium universal substrate suitable for ornamental plants, outdoor flowers, and indoor plants. Any container-grown plant will benefit from its excellent drainage and organic richness.
How does the Magnesium (Mg) contained in the formula help?
How does the Magnesium (Mg) contained in the formula help?
Magnesium is the engine of photosynthesis. By including it in our technical formula, we help plants maintain an intense green color and process sunlight better. This is vital in urban terrace gardens where plants are often subjected to greater thermal stress.
Is it suitable for organic home gardening?
Is it suitable for organic home gardening?
Absolutely. It is a 100% natural substrate, formulated with plant matter and organic fertilizers. As a locally sourced product produced in Granada, it is not only better for your plants, but also for the planet, by drastically reducing CO2 emissions linked to the transport of large volumes of soil.
What is the difference between worm castings and this vegetable garden substrate?
What is the difference between worm castings and this vegetable garden substrate?
The main difference is its function: worm castings are a pure fertilizer (a concentrate of life and nutrients) used in small quantities to "heal" or enrich the soil. In contrast, our urban garden substrate is the complete growing medium; it is the "soil" where the plant lives and develops its roots. Our mix already includes an ideal proportion of castings, but if you are looking for an extra energy boost for demanding plants or want to regenerate old soil, pure castings are the perfect supplement to add to this substrate.
How does this mixture differ from conventional compost?
How does this mixture differ from conventional compost?
Compost is decomposing organic matter that serves as fertilizer, but it lacks the physical structure necessary for a plant to grow on its own (it is usually heavy and retains too much water). Our urban garden mix, on the other hand, is a balanced technical substrate: it combines the nutritional richness of worm castings with coconut fiber and plant matter to ensure lightness and oxygenation. While compost is an "extra" for the soil, our substrate is the complete "ready-to-use" solution that prevents roots from suffocating or rotting.
