Plagron Bat-Mix with Perlite 50 l — 100% Organic Bat Guano Substrate for Maximum Bloom and Aroma
Flavour and aroma aren't added at harvest — they're built in the root zone. Plagron Bat-Mix with Perlite 50 l is a CU-certified organic substrate that delivers six weeks of complete nutrition through the slow-release power of bat guano, Plagron worm castings and premium peat. Within the Plagron substrate range, Bat-Mix is the organic grower's go-to for cultivations where sensory quality is the primary objective.
Bat Guano: Nature's Most Potent Bloom Booster
The performance driver in Bat-Mix is bat guano, processed under strictly controlled conditions to meet Plagron's quality standards. Naturally rich in phosphorus and potassium, bat guano is one of the most bioavailable organic nutrient sources available, directly stimulating vigorous flowering and amplifying the terpene and flavour profiles of the harvest. Combined with Plagron's proprietary worm castings, Bat-Mix creates a biologically active soil environment that enhances nutrient uptake and root vigour throughout the entire cultivation cycle.
- Bat guano — high in phosphorus and potassium: drives explosive flowering and intensifies aroma and taste in the final harvest.
- 6-week pre-fertilisation (organic NPK 5.5-11-5.5): zero additional nutrients required for the first six weeks.
- 10% integrated perlite: lightweight, airy structure with fast drainage and optimal root-zone oxygenation.
- Plagron worm castings: rich microbial soil life and improved water retention capacity.
- CU-certified (Control Union): independently verified 100% organic composition.
How to Use Plagron Bat-Mix with Perlite
Bat-Mix is nutrient-dense — water through before use to flush out some of the immediately soluble salts and reduce the risk of root burn, especially for young plants. Wait 1–2 weeks before transplanting very young seedlings or freshly rooted cuttings. Well-developed plants can be potted directly. No fertilisers are needed for the first six weeks. When lower leaves begin to show early signs of yellowing, it's time to start feeding with Plagron Alga Grow in the vegetative phase and Plagron Alga Bloom during flowering, supplemented with Plagron additives for peak output.
Where Bat-Mix Fits in the Plagron Range
Bat-Mix is the organic specialist in the Plagron substrate lineup. It excels in autoflowering cultivations of 8–10 weeks, where the plant can often complete its full cycle on substrate nutrients alone or with only a handful of supplemental feedings. If you want maximum yield through a fully organic time-release nutritional approach rather than guano-driven bloom intensity, compare with Plagron Royal-Mix, which delivers six weeks of complete fertilisation with a broader organic nutrient profile. Both substrates are 100% organic and CU-certified.

Does Plagron Bat-Mix with Perlite need to be rinsed before use?
Yes. Plagron recommends watering Bat-Mix through before use to remove some of the immediately soluble nutrients and reduce root burn risk for sensitive young plants. For well-established plants, direct potting is generally safe. Wait 1–2 weeks after transplanting very young seedlings before starting any supplemental feeding.
When should I start fertilising with Plagron Bat-Mix with Perlite 50 l?
Bat-Mix provides complete nutrition for approximately six weeks. The precise timing depends on light intensity, plant type and environmental conditions. A reliable indicator: when the lower (oldest) leaves begin to show slight yellowing, it's time to start with Alga Grow or Alga Bloom. Never start earlier than week four unless the plant clearly shows nutrient deficiency signs.
Is Plagron Bat-Mix with Perlite suitable for autoflowering plants?
Yes, Bat-Mix is particularly well-suited for autoflowering varieties with a lifecycle of 8–10 weeks. The organic nutrient release from bat guano often covers the plant's full growth and flowering requirements, meaning you can sometimes complete an entire run with only water and a few supplemental feedings near the end. The result is a naturally rich harvest with outstanding aroma and flavour complexity.
What are the EC and pH values of Plagron Bat-Mix with Perlite 50 l?
Plagron Bat-Mix has a pH between 5.8 and 7.0 (1:1.5) and an EC between 1.3 and 2.0 mS/cm (1:1.5). The higher EC reflects the substrate's rich organic nutrient content from bat guano and worm castings. Pre-rinsing before use and a brief acclimatisation period of 1–2 weeks are recommended for young or sensitive plants to avoid nutrient overload at transplant.
