STARTREX

STARTREX by BioTabs — Organic Soil Improver (NPK 3-1-2)

STARTREX by Biotabs activates a living substrate from day one. Its 100% organic formula (NPK 3-1-2) combines beneficial bacteria, fulvic acids, humus, and silica to speed up rooting, improve nutrient uptake, and build stronger, more resilient plants. Works in soil and coco, indoors and outdoors, in pots or open ground.

Why growers choose it

• Faster, uniform rooting after transplant.

• Improved nutrient availability for steady, healthy growth.

• Greater resilience to heat, wind, and general stress thanks to silica.

• Stable, airy substrate with active microbiology.

• Versatile use in soil or coco, pot or ground.

How to use Startrex

1. Mix thoroughly into the substrate before planting or transplanting.

2. Recommended dose: 25 g per 5 L of soil or coco (≈ two heaped tablespoons).

3. Water lightly after transplant to activate the microbiology.

4. Recycling substrate: reapply the same dose when you refresh or expand the medium.

Quick dose guide

Tip: on heavily pre-fertilised soils, keep the standard STARTREX dose and avoid adding other fertilisers in the first week.

Smart pairings

• Mycotrex (mycorrhizae): apply at root contact; mix STARTREX into the substrate for a stronger root system.

• Bactrex (beneficial bacteria): great for first irrigations or post-stress recovery.

• Orgatrex (liquid feed): complements the bioactive base created by STARTREX.

• Silicium Flash: quick silica boost in demanding phases—use without over-fertilising.
