Biotabs Fertiliser Tablets 10
Biotabs Fertiliser Tablets are organic slow-release fertiliser tablets with an NPK ratio of 15-7-8, designed to feed plants through the entire growth and flowering cycle with a single application. This 10-tablet pack provides enough fertiliser for 5 to 10 plants in 5-10 litre containers. Each 21-gram tablet contains bone meal, blood meal, feather meal, fish meal, natural humic acids and beneficial soil bacteria that condition the substrate while delivering nutrients at a biologically regulated rate. No pH adjustment, no EC monitoring, no liquid dosing schedules — push the tablets into your soil or coco at 5-10 cm depth and water normally. Explore the simplest path to fully organic cultivation with these Biotabs slow-release tablets.
Biotabs Fertiliser Tablets 10 pack — organic slow-release plant nutrition NPK 15-7-8
The core challenge of organic cultivation has always been nutrient delivery timing. Liquid organics require frequent application and precise dosing. Mineral slow-release granules lack biological activity. Biotabs Fertiliser Tablets solve both problems simultaneously by combining a slow-release NPK 15-7-8 formulation with live beneficial soil bacteria in a single 21-gram tablet. This 10-pack from Biotabs is the entry-level format for growers looking to evaluate the system before scaling up.
How the biological release mechanism works
Each tablet contains bone meal, blood meal, feather meal, fish meal, natural humic acids and beneficial soil bacteria. Once placed in moist substrate, the bacteria begin decomposing the organic matrix, converting it into plant-available macro and micronutrients. This biological mineralisation process is self-regulating — nutrient release accelerates when root activity and microbial metabolism are high, and slows when conditions are less demanding. The result is a steady nutrient supply that tracks actual plant requirements without the peaks and troughs associated with liquid feeding schedules.
Dosing protocol by container volume
- 5 litres — 1 tablet
- 10 litres — 2 tablets
- 20 litres — 3 tablets
- 30-50 litres — 4 tablets
- 60 litres — 5 tablets
- 70 litres — 6 tablets
Insert tablets at 5-10 cm depth, distributed near the pot edges to avoid direct root contact. Water thoroughly after placement. For maximum performance, pair the tablets with Biotabs Startrex soil conditioner and Mycotrex mycorrhizal inoculant to establish a fully functional soil microbiome from the outset.
10-pack: ideal for system evaluation
The 10-tablet format covers 5 to 10 plants in standard containers, providing enough product for a complete test cycle. Growers transitioning from liquid organic or mineral systems can directly compare results — typically reporting more uniform growth, reduced maintenance time and elimination of pH/EC monitoring requirements.
Biological vs. coated slow-release: a fundamental difference
Conventional slow-release fertilisers rely on synthetic coatings that dissolve at rates determined by temperature and moisture — regardless of actual plant demand. Biotabs tablets use an entirely different mechanism: biological decomposition by live soil bacteria. This means nutrient release is directly coupled to root zone activity. When the plant is actively growing and microbial metabolism is high, mineralisation accelerates. During dormant periods, the process slows proportionally. The result is a nutrient supply curve that matches the plant's actual requirements rather than an arbitrary chemical dissolution rate. Additionally, the beneficial bacteria actively improve soil structure, enhancing both water retention and aeration in the root zone.
For ongoing use at scale, the 100-tablet bulk pack offers significant per-unit cost savings.

How many Biotabs tablets do I need per plant?
Dosing is based on container volume rather than plant count. Use 1 tablet per 5 litres of substrate for containers up to 30 litres. For larger pots (40+ litres), reduce to 1 tablet per 10 litres. A 20-litre pot requires 3 tablets for full-cycle coverage.
Do Biotabs Fertiliser Tablets work in coco coir?
Biotabs Fertiliser Tablets are formulated for both soil and coco coir substrates. The application method is identical — push the tablets 5-10 cm into the coco and water normally. The beneficial bacteria in the tablets function effectively in both substrate types.
Is pH monitoring required when using Biotabs tablets?
No pH or EC monitoring is needed with Biotabs Fertiliser Tablets. The beneficial soil bacteria regulate nutrient availability through biological processes, eliminating the need for manual pH adjustment. Standard tap water is sufficient throughout the entire cultivation cycle.
How many plants does a 10-pack of Biotabs tablets cover?
A 10-tablet pack covers 5 to 10 plants in 5-10 litre containers (1-2 tablets each). In larger 20-litre containers requiring 3 tablets per pot, the pack covers approximately 3 plants for a full growth cycle.
