Biotabs Fertiliser Tablets 100
Biotabs Fertiliser Tablets in the 100-piece bulk format deliver the same certified organic NPK 15-7-8 slow-release formulation at a substantially lower cost per tablet. Each 21-gram tablet contains bone meal, blood meal, feather meal, fish meal, humic acids and beneficial soil bacteria that biologically regulate nutrient release throughout the full growth and flowering cycle. This volume supports 25 to 50 plants per cycle depending on container size, making it the standard choice for experienced growers running multiple rotations annually or managing larger operations. No pH correction, no EC adjustment, no liquid feeding — insert tablets at 5-10 cm depth and irrigate with plain water. Order this professional-grade bulk pack for maximum cost efficiency in organic cultivation.
Biotabs Fertiliser Tablets 100 pack — bulk organic fertiliser for professional-scale growing
Scaling organic cultivation demands a nutrient system that delivers consistent results without proportionally increasing labour and input costs. The Biotabs Fertiliser Tablets 100-pack provides exactly that — the same proven NPK 15-7-8 slow-release formulation as the 10-tablet entry pack, but at a volume that supports multiple cultivation cycles and larger plant counts. For growers who have validated the Biotabs method on a smaller scale, this is the logical next step in operational efficiency.
Cost-per-plant analysis
The economics of the 100-tablet format are compelling. Beyond the direct per-unit price reduction compared to the 10-pack, the Biotabs system eliminates several cost categories entirely: liquid base nutrients, pH correction solutions, EC meters and calibration fluids. When these eliminated costs are factored in alongside the bulk pricing, the total cost per plant of a Biotabs-based organic grow competes directly with conventional mineral feeding programmes while delivering certified organic output.
Capacity planning
The 100-tablet volume enables flexible deployment across varying operation sizes:
- 50 plants in 10-litre containers (2 tablets each)
- 33 plants in 15-litre containers (3 tablets each)
- 25 plants in 20-litre containers (4 tablets each)
- In-ground cultivation — insert tablets at 5-10 cm depth, distributed around each plant base
Unused tablets maintain full potency when stored in a cool, dry environment.
Maximising performance with complementary products
The biological nutrient release from Biotabs tablets operates at peak efficiency when the substrate contains an active microbial population. Pairing the tablets with Bactrex beneficial bacteria and Mycotrex mycorrhizal inoculant establishes this population from planting day. The mycorrhizal network extends root reach by up to 700%, while the Bacillus and Trichoderma strains in Bactrex protect against root pathogens and accelerate organic matter decomposition. Adding Orgatrex liquid feed from week five completes the nutritional programme.
Substrate reuse and long-term soil building
A key operational advantage of the Biotabs tablet system at scale is substrate reusability. After each harvest, the growing media retains an established microbial population that can be reactivated by refreshing the top layer with Startrex and Mycotrex. This reduces substrate waste, lowers input costs per cycle and progressively improves soil quality. Experienced Biotabs users frequently report improved performance in successive cycles as the soil biology matures and stabilises, creating a self-reinforcing system that delivers increasingly consistent results.

What cost savings does the 100-pack Biotabs offer over the 10-pack?
The per-tablet cost decreases substantially in the 100-pack format compared to the 10-pack. For growers managing 20 or more plants per cycle, this saving compounds across multiple rotations and significantly reduces the overall cost of organic fertilisation.
Can Biotabs tablets be used for in-ground cultivation?
Biotabs Fertiliser Tablets perform well in both container and in-ground applications. For in-ground planting, push the tablets 5-10 cm into the soil around each plant base. The nutrients diffuse through a larger soil volume in open ground, allowing slightly wider spacing between tablets.
How should unused Biotabs tablets be stored?
Store tablets in their original packaging in a cool, dry location away from moisture. The organic ingredients and beneficial bacteria maintain their effectiveness indefinitely as long as the tablets remain dry.
Are Biotabs tablets compatible with other brands of organic nutrients?
Biotabs tablets deliver optimal results within the complete Biotabs system (Startrex, Mycotrex, Bactrex, Orgatrex). Adding mineral or synthetic fertilisers is not recommended as these can disrupt the biological soil equilibrium that the tablets establish and rely upon for nutrient delivery.
