Advanced Nutrients Sensi Terra Part 1 & 2 - Two-Part Base Nutrient for Soil Growers
Best for: Soil and peat-based growers who want the Sensi nutrient profile built specifically for their medium, not adapted from a hydro formula.
Our thoughts
A lot of "soil nutrients" are really hydro formulas with the marketing changed. Sensi Terra is built from the ground up for soil and peat mixes, which matters because soil buffers and holds nutrients very differently to a hydro reservoir. If you're growing in soil, this is the Sensi line to reach for rather than the standard Sensi Grow/Bloom liquid range.
Sensi Terra is Advanced Nutrients' two-part base nutrient built specifically for soil and peat-based growing mixes, distinct from their Sensi Grow/Bloom liquid range which is formulated for hydroponic and recirculating systems. Part 1 carries plants through early growth and the veg-to-bloom transition, while Part 2 is introduced during flower to shift the nutrient balance toward what soil-grown plants need to focus energy on flower development rather than continued foliage growth. The line is formulated with zero nitrogen in late flower, aimed at directing the plant's remaining energy into flowers rather than leaf growth right before harvest.
Because it's designed around soil and peat chemistry specifically - which naturally buffers pH and holds nutrients differently to a hydro reservoir - Sensi Terra aims to deliver stable pH and clean nutrient inputs across the full grow cycle without the swings that can happen when a hydro-formulated nutrient is used in soil.
How it compares
Sensi Terra sits alongside the other major soil-specific base nutrient lines rather than against general hydro nutrients.
- Vs Canna Terra Vega/Flores: Canna Terra is probably the best-known soil-specific two-part range in the UK market; both brands build around soil-specific buffering rather than adapting a hydro formula.
- Vs BioBizz Bio-Grow/Bio-Bloom: BioBizz is organic-certified and leans on a more "living soil" philosophy; Sensi Terra is a mineral-based formula giving tighter control over exact nutrient ratios.
- Vs Advanced Nutrients' own Sensi Grow/Bloom (liquid, hydro-formulated): using the hydro version in soil can lead to nutrient build-up over time since soil doesn't flush the way a hydro reservoir does - Sensi Terra is built to avoid that.
If you're growing in soil, a soil-specific formula like this generally outperforms a hydro nutrient adapted for the job.
Usage guidance
Sensi Terra is fed across the full grow cycle, with a switch from Part 1 to Part 2 partway through flower.
Dosage range
Use between roughly 1ml and 7ml per litre, from the clone or seedling stage through to your final flush, adjusting strength up as plants mature.
Feeding frequency
For soil and soilless blends, feed 2 to 4 times a week as needed rather than at every watering, letting the medium's natural buffering do some of the work between feeds.
Switching from Part 1 to Part 2
Feed Part 1 through veg and the early flip into flower, then switch to Part 2 around week 2 of flowering to shift the nutrient balance toward finishing flowers.
Late flower
The zero-nitrogen late-flower formulation is designed to be run right through to your final feeds, helping avoid excess leafy growth just before harvest.

Who this is for
- Soil and peat-mix growers who want a base nutrient built for their medium rather than adapted from hydro
- Growers wanting a single two-part line that covers veg through to finished flower
- Anyone frustrated by nutrient salt build-up from using a hydro-formulated feed in soil
Not intended for hydroponic or recirculating systems - use Advanced Nutrients' Sensi Grow/Bloom range for those instead.
Our take
This is the right Sensi product to reach for if you're growing in soil rather than hydro - it's built around how soil actually holds and releases nutrients, not adapted from a formula designed for a reservoir.
Proper kit for soil growers who want a dedicated two-part system rather than making a hydro nutrient work outside its intended medium.
