BioGreen Soil Feed Chart – Grow 1 and Bloom 2 Doses
BioGreen's own published Soil, Grow 1 and Bloom 2 schedule. If your base feed is one bottle marked Grow 1 for veg and a second marked Bloom 2 for flower, this is your chart — if it is two bottles marked Part A and Part B, you want the Soil A&B chart. Week by week, in millilitres per one litre of water.
- All dosesper 1 litre
- pH5.8 – 6.2
- Base feedGrow 1 to 1.5ml, then Bloom 2 to 2ml
Every figure is millilitres per one litre of water. Multiply by ten for a 10-litre watering can — so 1.75ml here is 17.5ml in a full 10-litre can. A dash means the bottle is not used that week.
Getting it right
- Grow 1 and Bloom 2 overlap for exactly one week. Flower 1 is the changeover: 1.25ml of Grow 1 and 0.25ml of Bloom 2 in the same can. After that Grow 1 stops for good and Bloom 2 takes over on its own.
- These are per-litre doses, not per ten litres. Read the figure, then multiply by the number of litres you are mixing. Several of them are quarter-millilitres, so a syringe beats a measuring cap.
- Calgel has a weekly dose on this chart. That is the clearest difference from BioGreen's other soil schedule, where Calgel carries no figure at all. Here it runs from 0.25ml at Grow 1 up to 0.4ml at Flower 6, then back to 0.3ml from Flower 7 to Flower 9.
- PK 13/14 and X-Blast are not run together. BioGreen print that instruction on the chart: PK 13/14 at Flower 3 and Flower 4, X-Blast from Flower 5 onwards. Both appear against the later columns of the grid, so pick one.
- The boosters are dosed lower here than on the A&B soil chart. PK 13/14 peaks at 1ml and X-Blast at 1ml on this schedule; on the Soil A&B chart both peak at 1.5ml. Do not carry figures across between the two.
- X-Force is measured in fractions of a millilitre. 0.1ml from Cutting 1 to Grow 4, 0.15ml from Flower 1 to Flower 9. That is 1ml and 1.5ml in a 10-litre can.
- pH moves once, part way through flowering. BioGreen print 5.8–6.0 from Cutting 1 to Flower 4, then 6.0–6.2 from Flower 5 to the final plain-water week.
- This chart has no EC row. BioGreen give EC targets on their coco, hydro and Soil A&B charts but not on this one, so go by the millilitre figures and the pH.
- The plain-water week is not an empty one. Calgel, Bloom 2, X-Rooting, PK 13/14, X-Blast, X-Force and Garlic all stop. Biozym goes in at 3ml and X-Bloom at 2ml.

Common questions
How do I know this is my chart and not the other BioGreen soil one?
Look at the base feed. One bottle labelled Grow 1 for veg and a second labelled Bloom 2 for flower means this chart. Two bottles labelled Part A and Part B, dosed together at the same rate, means the Soil A&B chart. The additive doses differ between the two, so it matters.
Do I really run Grow 1 and Bloom 2 in the same can?
For one week only. Flower 1 carries 1.25ml of Grow 1 and 0.25ml of Bloom 2. From Flower 2 onwards Grow 1 is finished and Bloom 2 runs on its own at 1.5ml, rising to 2ml.
Why does Calgel have a dose here but not on the A&B charts?
That is how BioGreen print them. This soil chart gives Calgel a figure for every week from Grow 1 to Flower 9. The coco, hydro and Soil A&B charts replace it with a rule instead: bring soft water up to EC 0.6 with Calgel before feeding.
What pH should I be at?
5.8 to 6.0 from Cutting 1 through to Flower 4, then 6.0 to 6.2 from Flower 5 to the final plain-water week. Check it after everything is mixed.
Where are the EC targets?
This chart does not have them. BioGreen publish EC by week on their coco, hydro and Soil A&B charts, but the Grow 1 and Bloom 2 soil chart carries only pH.
