MONKEY

Monkey Nutrients run one chart for coco, soil and hydro — Grow then Bloom, with the same rates whatever you are growing in. The chart below is MONKEY’s own schedule, with the target EC on every week. Underneath it, our free calculator fits it to your pot size, plant count and cycle length, and works out exactly how much you need to buy.

The Monkey Nutrients — PK 14/15 feed chart

Millilitres per litre of water. Veg here is four weeks and flower nine, which is the commonest UK cycle. If yours is longer or shorter, the calculator fits the same schedule to it rather than simply running out.

Swipe the chart sideways to see every week.

Week Grow A+B Root Shoot Bloom A+B Boost PK 14/15 Target EC
Veg week 1 1.5 0.2 1.2
Veg week 2 1.5 0.2 1.3
Veg week 3 1.5 0.3 1.4
Veg week 4 1.5 0.3 1.5
Flower week 1 0.3 2.0 1.6
Flower week 2 0.3 2.0 1.0 1.7
Flower week 3 0.3 2.5 2.0 1.8
Flower week 4 0.3 2.5 2.0 0.25 1.9
Flower week 5 0.3 2.75 2.0 0.25 2.0
Flower week 6 2.75 2.0 0.5 2.1
Flower week 7 3.0 2.0 2.2
Flower week 8 3.0 2.0 1.9
Flower week 9 3.0 2.0 1.9

Target pH 5.5 to 6.5.

The finisher is the only real fork

Monkey publish two charts and they are identical until the last stretch. One finishes on PK 14/15, the other on Resin. Everything before that point is the same.

Both are in the calculator as separate lines, so you can price the two finishers against each other. It is one of the cleaner decisions on this site: same grow, same base, one product different.

Mix to the EC, not to the millilitres

The doses above assume your water starts at zero. UK tap water usually sits between 0.3 and 0.5 EC before you add anything, and that counts towards the targets in the last column.

So on tap water you will reach the chart’s own EC with slightly less nutrient than it prints. Use the doses to get close and the meter to know. On RO, the printed figures are the ones to run.

What a full Monkey Nutrients run costs

For a common UK setup, nine plants in 3 gallon Quick Fill coco bags, four weeks of veg and nine of flower, the whole cycle comes to about £193 across 5 products, mixing roughly 1,500 litres of feed.

The single biggest line on that bill is Monkey Boost at around £80, against £40 for the base feed itself. That is worth knowing before you order, because it is usually the additives rather than the base that decide what a run costs.

The calculator prices your actual grow rather than this example, and prices the other fifteen brands alongside it, so you can see what you are paying for.

Which MONKEY line should I be on?

The two lines are the same schedule with a different finisher.

The calculator only ever lists the lines that suit the medium you pick, so you cannot accidentally run a soil chart in coco.
