Tarantula. By Advanced Nutrients. 

Let’s talk roots. Because no matter how dazzling your lighting rig is or how perfectly dialled in your environment may be, if your root zone is struggling, the rest of your grow will suffer. It’s the classic underground battle - unseen, but utterly decisive. This is where Advanced Nutrients Tarantula swoops in with all the subtlety of a precision microbial airstrike. Built by the botanical boffins at Advanced Nutrients, this is a powerhouse of beneficial microbes bottled for your convenience, and it means business. If your grow isn’t already running Tarantula, then frankly, your roots are on the back foot. 

For Monster Roots. 

Advanced Nutrients Tarantula isn’t some wishy-washy biological tonic. It’s a high-potency microbial formula featuring a staggering 11 strains of beneficial bacteria, all specifically bred for performance in hydroponic and soil-based systems. Each millilitre contains a writhing horde of root-friendly organisms like Bacillus Subtilis, Paenibacillus Polymyxa, and the tongue-twisting Bacillus Thuringiensis Canadiensis - each one carefully selected to do a very specific job. These aren't generic soil microbes - this is a curated microbial task force designed to colonise the rhizosphere, outcompete nasties, and turn your root zone into a nutrient-processing machine.

Defence Against Root Pathogens.

What makes Advanced Nutrients Tarantula stand out is its sheer concentration and diversity. Used from the seedling or cutting stage through to the second week of bloom, it supercharges root branching, dramatically increases root mass, and provides a natural line of defence against root-borne pathogens. It does this by forming dense microbial colonies around the roots, which not only improve oxygen levels but also convert otherwise inaccessible nutrients into plant-available forms. The result? More nutrient uptake, less disease, and an immune system that’s ready for anything.

Without Compremise.

One of the most unsung aspects of indoor growing is microbial support. In soil, plants naturally build symbiotic relationships with these microbes - but in hydroponic systems, especially those using sterile environments or tap water loaded with chlorine, this biological advantage is often stripped away. Advanced Nutrients Tarantula reintroduces that vital microbial activity, restoring the plant’s natural mechanisms for resilience and efficiency. If you’re serious about root health, it’s not optional.

Tarantula is a Live Product. 

As you’d expect, Advanced Nutrients Tarantula plays nicely with the rest of the Advanced Nutrients ecosystem. It’s particularly effective when used in tandem with products like Voodoo Juice, offering a broader microbial spectrum for even more dynamic results. The formula is highly soluble, user-friendly, and blends seamlessly into any nutrient schedule at just 2ml per litre. But do be warned: steer clear of peroxide additives unless your goal is microbial annihilation. Tarantula is a living product, and hydrogen peroxide will obliterate the beneficial bacteria you’ve just paid good money to introduce.

Strong Roots Make Strong Plants.

Available in two sizes, Advanced Nutrients Tarantula scales well from compact cupboard grows to full-blown industrial setups. Whether you’re nurturing a few discreet plants or managing a facility that smells like a botanical research lab, this is a foundational product that should be in your feeding regime. The science is solid, the results are visible, and the payoff is in your yields. Strong roots make strong plants. And Advanced Nutrients Tarantula gives your roots exactly what they need to dominate the underground.
