Getting your nutrient dosing right is one of the most important factors for a successful grow. Whether you're using our liquid All-in-One formula, the organic Vegan Grow & Bloom line, or our slow-release Monster Bud Mix granular fertilizers, the schedules below tell you exactly how much to use and when.

Each schedule is based on 10 litres of nutrient solution. All liquid dosages are in millilitres (ml) per 10L of water. Simply scale up or down proportionally for your batch size (e.g. for 5L, halve the values; for 20L, double them).

How to read the tables

How to read the tables

  • ml / 10L: millilitres of product to add per 10 litres of water.
  • EC: Electrical Conductivity, a measure of nutrient strength in your solution. Use an EC meter to check your mix matches the target value. EC values do not scale with volume; they are target readings.
  • <20: means "less than 20 ml". Gradually reduce the dose during this stage.
  • –: means the product is not used during that stage. Do not add it.

All-in-One Liquid & All-in-One Autoflower

Our single-bottle base nutrients: one for photoperiod strains, one optimised for autoflowers. Both use the same base dosage; only the target EC differs. Combine with PK 13-14, Max Flavour, and Max Yield boosters for maximum results.

Vegan Grow & Bloom

A two-part organic base nutrient system. Vegan Grow and Vegan Bloom are used simultaneously: the ratio shifts as your plant transitions from vegetative growth into flowering. This line uses Vegan PK as its phosphorus-potassium booster (not PK 13-14).

Monster Bud Mix: Granular Fertilizers

Our slow-release granular fertilizers are mixed directly into the soil before planting. No weekly base dosing required: just mix once and the soil does the work.

Base dose (mix into soil before planting):
  • Monster Bud Mix: 75 grams per 10-litre pot
  • Monster Bud Mix, Living Soil: 110 grams per 10-litre pot
Scale proportionally for other pot sizes (e.g. a 20L pot needs double, a 5L pot needs half).

While the granular base handles your plant's core nutrition, you can boost results further with these liquid additives mixed into your watering solution:

Tips for best results

  • Always measure your EC: An EC meter is your best friend. After mixing your nutrients, check that the EC matches the target value in the schedule. If it's too high, dilute with more water. If it's too low, add a little more base nutrient.
  • Keep your pH in range: Cannabis grows best at a pH between 5.8 and 6.5 (for hydro/coco) or 6.0 and 7.0 (for soil). After mixing your nutrients, check the pH and adjust with Zamnesia pH- (to lower) or pH+ (to raise) until you hit the sweet spot. Always adjust pH after adding all nutrients.
  • Start lower, work up: If you're new to growing or using a sensitive strain, start at 50-75% of the recommended dose and increase gradually. Watch how your plants respond.
  • Don't skip the flush: The final rinse week with plain water helps remove built-up salts from the growing medium, leading to a cleaner, smoother end product.
  • Boosters are optional but recommended: The base nutrients contain everything your plant needs. PK 13-14 (or Vegan PK), Max Flavour, and Max Yield are extras that push quality and yield further. You can use any combination of them.
  • Never mix concentrates directly: Always add each product separately to your water, stirring well between additions. Mixing concentrates together before diluting can cause nutrient lockout.
  • Water temperature matters: Aim for 18-22 degrees C. Cold water reduces nutrient uptake; warm water holds less dissolved oxygen.
