Grower Tip
- Add Part A to water first and stir, then add Part B — always use equal amounts of both parts.
- Dose 2mL/L of each part for roughly EC 1.0, or 4mL/L for EC 2.0 — verify with your meter.
- Hold pH at 5.8–6.2 through grow and bloom, then flush at pH 7.0 in the final week.
- For strains that want extra calcium or nitrogen, add Marine CaMg+ at 0.25–1mL/L instead of raising base rates.
Features
Supplies every macro and micronutrient plants need from clone through to late bloom in one A+B pair.
High-purity minerals blended with natural chelates, organic metabolites, and fulvic and humic acid — the bio-fused difference over standard two-part bases.
Added trace elements, B vitamins and bio-stimulants support fast, vigorous growth and heavy flowering.
Formulated for high-performance recirculating hydroponic and coco fibre run-to-waste systems, with a dedicated feed chart for each.
2mL/L of each part lands around EC 1.0 (500 ppm); 4mL/L around EC 2.0 (1000 ppm).
Each option includes both parts — 2x1L, 2x5L or 2x20L — so Part A and Part B run out together.
-
1
Fill your reservoir
Fill with water and keep the solution oxygenated with a circulation pump or air stone.
-
2
Add Part A
Measure Part A at the feed-chart rate for your stage (1–4mL/L), add to the water and stir well.
-
3
Add Part B
Add the same amount of Part B and stir again.
-
4
Check EC
Confirm strength with an EC meter — 2mL/L of each part is roughly EC 1.0; 4mL/L is roughly EC 2.0.
-
5
Set pH
Adjust to pH 5.8–6.2 depending on stage, per the feed chart.
-
6
Flush to finish
In the final week, stop feeding and flush with plain water at pH 7.0.
What dose rate should I use?
Follow the Bio Diesel feed chart: 1mL/L of each part for clones and early veg, 2mL/L through veg, up to 4mL/L in late veg, and 3–4mL/L through bloom depending on your system. Use equal amounts of Part A and Part B, and flush with plain water in the final week.
Do I use both Part A and Part B every feed?
Yes — every feed uses both parts in equal amounts, but add them to the water one at a time. Add Part A first and stir, then add Part B and stir again. As a guide, 2mL/L of each part gives roughly EC 1.0; 4mL/L gives roughly EC 2.0.
Can I use Green Diamond in coco?
Yes. Green Diamond is designed for high-performance hydroponic and coco fibre systems, and Bio Diesel publishes a dedicated coco run-to-waste feed chart alongside the recirculating hydro chart. Keep solution pH between 5.8 and 6.2, and for run-to-waste coco water with shorter, more frequent feeds during lights-on.
Which size should I choose?
Every size is a twin pack with equal Part A and Part B. At the mid-range 2mL/L rate, the 2x1L pack makes about 500L of solution, the 2x5L about 2,500L and the 2x20L about 10,000L — halve those figures at the full 4mL/L bloom rate. Small tents suit 2x1L; regular growers usually step up to 2x5L.
Do I need additives with it?
Green Diamond covers all essential macro and micronutrients on its own, but it's designed as the backbone of the full Bio Diesel range. For best results, follow the feed chart and pair it with Super Natural for roots, Marine CaMg+ for extra calcium and nitrogen, Aloevate as a plant tonic, and Bio Diesel bloom booster and Rhino K through flower.
Description
FULL SPECTRUM BASE NUTRIENT FOR ALL STAGES OF GROWING
Base nutrient rich in ALL required macro and micronutrients required for fast, vigorous growth and heavy flowering.
Designed for high performance Hydroponic and Coco Fibre systems.
It contains natural chelates and organic plant metabolites, combined with pure minerals of the highest quality.
Additional Trace elements, B Vitamins, Fulvic acid and Bio Stimulants are added to produce a powerful Bio-fused nutrient, complete in all micro and macro minerals needed for healthy plant production across all stages of growth.
Green Diamond is different to other 2 Part base nutrients on the market as it contains a bio-mineral suspension that includes organic metabolites, Fulvic and Humic acid as well as a mix of vitamins for faster growth.
