Emerald Harvest 3-Part Feed Chart – Grow, Micro, Bloom
Emerald Harvest's own published Grow, Micro and Bloom 3-part schedule. Week by week, in millilitres per one litre of water.
- All dosesper 1 litre
- pH5.8 – 6.3
- Base feedGrow, Micro and Bloom together
Every figure is millilitres per one litre of water, not per ten. A 10-litre watering can takes ten times what you see here — Bloom at 2.75ml per litre is 27.5ml in a 10-litre can.
Getting it right
- This is the three-bottle range. If your bottles read Grow, Micro and Bloom, this is your chart. If they read Cali Pro Grow A, Grow B, Bloom A and Bloom B, you want the Emerald Harvest Cali Pro feed chart instead. The two are different base ranges, not one range for two growing media.
- Never premix the concentrates. Emerald Harvest are firm about this. Fill the tank with water first, then add MICRO, then GROW and BLOOM. Pour two concentrates straight into each other and you get a sludge that never redissolves.
- All three bottles run every week. Grow does not stop at the flip. It climbs 0.5ml, 1ml, 1.5ml, 2ml through the four Grow weeks, drops to 1ml at Flower 1 and 0.5ml from Flower 2 to Flower 5, comes off for Flower 6, 7 and 8, then returns at 0.5ml for Flower 9.
- Micro is the steady one. 0.5ml at Grow 1 and 2, 0.75ml at Grow 3, then 1ml through to Flower 3, 1.25ml at Flower 4 and 5, 1.5ml at Flower 6 and 7, 1ml at Flower 8 and 0.5ml at Flower 9.
- Bloom does the heavy lifting late. It sits at 0.25–0.5ml through the Grow weeks, steps to 1ml at Flower 1 and 2ml at Flower 2 and 3, then 2.5ml at Flower 4 and 5 and 2.75ml for Flower 6, 7 and 8.
- Emerald Goddess starts at Grow 3. 1.5ml a litre from Grow 3 to Flower 1, 2ml at Flower 2 and 3, 2.5ml from Flower 4 to Flower 7, then 1.25ml at Flower 8.
- King Kola is flowering only. 1ml at Flower 1, 2ml at Flower 2 and 3, 3ml at Flower 4 and 5, 2ml at Flower 6 and 7, 1ml at Flower 8.
- Honey Chome carries on to the last week. 1ml from Grow 3 to Flower 1, 2ml from Flower 2 to Flower 7, then 1.5ml at Flower 8 and Flower 9.
- Root Wizard is two doses, not a weekly feed. 3.75ml a litre at Grow 3, and 3.75ml again at Flower 2. Nothing in any other week.
- Flower 9 is the wind-down. Grow, Micro and Bloom all drop to 0.5ml and Honey Chome to 1.5ml. Emerald Goddess, King Kola and Root Wizard stop.
- Keep pH between 5.8 and 6.3. One range for soil, coco and hydroponics, so the pH window is the same whatever you grow in.

Common questions
Is this per litre or per 10 litres?
Per one litre. Bloom at 2.75ml means 2.75ml in a 1-litre jug, or 27.5ml in a 10-litre watering can.
How do I know if I own the 3-Part or Cali Pro?
Read the bottle. Three bottles marked Grow, Micro and Bloom is the 3-Part range and this chart. Four bottles marked Cali Pro Grow A, Grow B, Bloom A and Bloom B is the two-part range, which runs on the Cali Pro feed chart. They are two different base feeds, not one feed for two growing media.
Can I mix Grow, Micro and Bloom together in a bottle first?
No. Emerald Harvest print the warning on every label: never premix concentrated nutrients. Fill the tank with water, add MICRO and stir, then add GROW and BLOOM.
Why does the chart restart at 1 when flowering starts?
Emerald Harvest write their own sheet in stages — Seedlings and Cuttings, Transplants, Early Vegetative, Late Vegetative, then Week 1 to Week 9. Growers count flowering from the flip, so ours renumbers those as Grow 1 to Grow 4 and Flower 1 to Flower 9. The doses are unchanged.
Does this work in soil, coco and hydroponics?
Yes. It is one schedule for all growing media, at pH 5.8 to 6.3.
Do I need all four boosters?
No. Grow, Micro and Bloom are the feed and will grow a crop on their own. Emerald Goddess, King Kola, Honey Chome and Root Wizard are add-ons, and each one has its own weeks on the chart.
