Every figure is grams of powder per 4 litres of water. For a 10-litre can, multiply by 2.5: RAW Bloom at 8g becomes 20g.

Getting it right

• Weigh it, do not scoop it. Everything here except Terpz is a soluble powder. A level teaspoon of one powder can weigh twice what another does, so a set of scales that reads to 0.01g is the right tool.
• RAW Grow and RAW Bloom never overlap. Grow runs 4g, 4g, 6g and 6g through the four Grow weeks. Bloom takes over at Flower 1 at 4g, goes to 6g, then 8g from Flower 3 to Flower 6, and back to 6g at Flower 7.
• Feed once or twice a week. NPK's pattern is feed, water, feed, or feed, water, water, feed, with water alone in between when the plants need it. Do not overwater: NPK say it is generally safe to water once the top 2.5–5cm of the medium feels dry.
• Check the pH before the microbes go in. NPK ask for the pH to be checked before you add Microbes Grow or Microbes Bloom, and before you feed. Aim for 6.0.
• Treat the ppm as a ceiling. NPK aim for 600–800 ppm through Grow and 800–1000 ppm in Flower. Start low. It is far easier to add feed than to get it back out of the medium.
• Test your runoff. In soil or coco, if the runoff reads much higher than what you just fed, use less feed, or none, at the next watering.
• The microbes switch at the flip. Microbes Grow at 2–4g through all four Grow weeks, then Microbes Bloom at 2–4g from Flower 1 to Flower 6.
• Enzymes go in every week. 0.25g per 4 litres in every column, Grow 1 to Flower 8.
• Phosphorus and Potassium are short bursts. Phosphorus 0.35g at Grow 2, then 0.7g from Flower 1 to Flower 3. Potassium 0.95g from Flower 4 to Flower 6, with Full Up at 0.3g in the same three weeks.
• Amino Acids taper through Flower. 0.6g at Grow 1, 1.2g from Grow 2 to Flower 1, 0.8g at Flower 2 and 3, 0.6g at Flower 4 and 5, then 0.3g at Flower 6 and 7.
• B-Vitamin and Cal-Mag come and go. B-Vitamin 0.6g at Grow 1 and Grow 4, 0.6g at Flower 2 and 3, 1.25g at Flower 4 and 5, 0.6g at Flower 6. Calcium/Mag 0.55g at Grow 2, 1.1g at Grow 3 and 4, 0.55g from Flower 1 to Flower 4, then 0.2g at Flower 5 and 6.
• Terpz is the one liquid. 5–10ml per 4 litres through Grow, then 10–15ml from Flower 1 to Flower 7. It is the one row on the chart we do not stock.
• The last column is different. Flower 8 drops RAW Bloom and runs Yucca, Cane Molasses and Enzymes only. Yucca is 1.2g in 19 litres, not 4. Cane Molasses is 0.9g per 4 litres.

Everything on the chart

Common questions

Why per 4 litres and not per 10?

That is how NPK publish it. For 10 litres, multiply by 2.5, so RAW Grow at 6g becomes 15g.

Can I use teaspoons instead?

NPK do print a teaspoon version, but powders pack differently, so a spoon is a rough measure. Grams are exact.

Do I need every product on the chart?

No. RAW Grow and RAW Bloom are all-in-one feeds and will grow a crop on their own. Everything else is a single-element top-up or supplement, used only in the weeks shown.

Is this a soil chart or a hydro chart?

NPK file it as their soil feed chart, and their notes are written for soil and coco growers.

What does 1.2g per 19 litres mean on the Yucca row?

Yucca is dosed per 19 litres, not per 4. It appears once, in Flower 8.

Why does Flower start again at week 1?

NPK number it that way themselves: four Grow weeks, then Flowering weeks 1 to 8.
