Nothing matches all of those filters.
Powders and dry concentrates
Made up with water. The cheapest way to buy a feed by volume, and the lightest to post.
Organic feeds
Plant and animal derived rather than mineral salts.
Three part feeds
Grow, Micro and Bloom mixed to a schedule. The most control over the ratio.
Two part feeds
An A and a B, mixed in equal measure. Less to weigh than a three part.
One part feeds
One bottle, one dose. The simplest way to feed.

Base nutrients for coco, hydro and soil
Every feeding schedule starts here. A base nutrient supplies the core NPK and trace elements your plant needs from the day it goes into final medium through to the last week of flower, and almost every serious line splits it into an A and a B bottle so calcium and phosphates don't lock out in the jug. Get the base wrong for your medium and no amount of booster fixes it, so this is the one bottle worth buying right first time.
Coco, hydro and soil each pull nutrients differently, which is why we stock separate coco, terra and hydro versions of most ranges rather than one bottle for everything. Coco holds almost no nutrient itself, so you're feeding at every watering, typically 1.2 to 1.8 EC through veg rising to 1.8 to 2.2 EC in flower depending on the strain and run-off you're seeing. Soil buffers more gently and forgives a slightly heavier hand. Hydro systems recirculate the same solution for days, so getting the starting EC and pH right matters even more since there's no fresh run-off to dilute mistakes.
What's on the shelf
- Canna — Coco A&B, Terra Vega & Flores and Aqua Vega & Flores, plus Hydro Vega & Flores for recirculating systems and Vega Start for young plants moving into final pots.
- Shogun — British-made Samurai Coco A&B and Samurai Terra Grow and Bloom, sold as single bottles or as Coco and Terra multipacks that bundle the whole line at a lower cost per litre.
- Dutch Pro — Original Grow and Bloom in separate Hydro/Coco and Soil formulas, built for growers running bigger volumes who want a no-nonsense two-part without the premium price tag.
- Atami, Athena and BioBizz — B'Cuzz Coco and Hydro Nutrition A&B, the Athena Blended Grow and Bloom line for fertigation setups, and BioBizz's certified-organic Bio-Grow and Bio-Bloom for soil growers.
Picking the right one
If you're growing in coco, start with a dedicated coco A+B rather than a soil or hydro formula — coco needs calcium topped up constantly and a generic base won't cover it. Our feeding in coco guide covers EC and pH targets week by week if this is your first run in the medium. For hydro and recirculating systems, check compatibility with your reservoir size on the tanks and reservoirs page, and pair any base feed with a decent pH or EC meter so you're dosing on numbers rather than guesswork.
