BioTabs is organic growing without the bottles. You mix the powders into the medium at the start, push in the slow-release tablets, and the soil biology feeds the plant for the rest of the cycle. For growers who want to water with plain water and stop thinking about EC, this is the shortest route there.
- Slow release tablets: The BioTabs fertiliser tablets that release nutrition gradually over months - the core of the system. See all organic nutrients.
- Soil biology: Bactrex for beneficial bacteria and Mycotrex for mycorrhizal fungi, both mixed into the medium at planting. Browse beneficials and inoculants.
- Starters: Startrex as the pre-plant soil conditioner and the Master Starter Pack, which brings the whole system together in one box.
- Liquid support: Orgatrex organic liquid feed and Guerrilla Juice 500ml where plants need a top-up.
- Flowering: BioTabs PK 5-8 and the PK Booster Compost Tea for the flowering push - see PK boosters.
- Plant health: Silicium Flash for cell strength and Boom Boom Spray as a foliar tonic for stressed plants.
- Outdoor: Guerrilla Tabs and the Guerrilla Box, designed for outdoor plots you cannot visit often.
Why choose BioTabs?
Because it takes feeding off the daily list entirely. Set the medium up correctly at the start and the plant draws what it needs when it needs it. No pH pen, no EC meter, no mixing - just water. For a first grow, or a plot you can only visit weekly, it is hard to beat.
BioTabs FAQs
Do I really just water with plain water?
For most of the cycle, yes. That is the whole design. Heavy feeders in long cycles may want Orgatrex or the PK Booster tea later on.
Can I use BioTabs in coco?
It is designed for soil and soil-like mixes with biology to activate. Coco is inert and drains too fast for the system to work as intended.
Do I need to pH the water?
No. A living soil buffers itself, and adjusting pH would work against the biology doing the feeding.
