Start with three things: your growing medium, source water and plant stage. For soil and suitable hydro systems, choose the Ferro Soil/Hydro A&B range. For coco, choose the Coco range. Growth and Bloom are separate base feeds, so match the version to the stage.
Using reverse osmosis water? Choose the corresponding Osmosis A&B range for soil/hydro or coco. Measure your water first. The description “soft water” alone does not explain its mineral composition. Do not automatically add extra calcium and magnesium to a complete osmosis feed.
Our advice: select your base feed first. Then check whether the schedule calls for a root stimulator, enzyme product or bloom supplement. A larger container does not change what the formula is designed for.
Ferro Volzet A&B is a starter feed for soil and hydro. Growth A&B is for vegetative growth; Bloom A&B is for flowering. In coco, choose Coco Growth or Coco Bloom. Do not switch purely by calendar: check the actual plant stage and the schedule for your range.
Bio Roots is a root stimulator, Enzym Plus an enzyme product and PK enriched a bloom supplement. Each has a separate role and does not automatically replace the appropriate A&B base. Cleaners and pH adjusters serve other purposes; do not treat them as extra base feed.
| Choice | Soil/Hydro Growth A&B | Soil/Hydro Osmosis Growth A&B | Coco Growth A&B |
|---|---|---|---|
| Application | Vegetative growth in soil/hydro | Vegetative growth in soil/hydro with RO water | Starting and vegetative growth in coco |
| Format | Two components: A and B | Two components: A and B | Two components: A and B |
| Bloom-stage counterpart | Soil/Hydro Bloom A&B | Soil/Hydro Osmosis Bloom A&B | Coco Bloom A&B |
| Check | Use the schedule for your medium | Check your source water | Choose standard or osmosis separately |
Fill a clean reservoir with a known volume of water. Measure A, add it to the water and mix. Then add B and mix again. Never pour the concentrates directly together. Use equal amounts of A and B where the chosen feed schedule specifies this. Use clean measuring jugs and avoid returning mixed liquid to the bottles.
There is no single dose for every Ferro product. Choose the schedule for your medium, water and plant stage. Use pH and EC meters after mixing and after adjustments. EC measures total conductivity, not the amount of each individual nutrient. Read why measuring pH and EC matters.
Tell us your growing medium, source water and plant stage. We will help you choose the appropriate nutrient range.

Size your reservoir with measured consumption and a realistic refill interval. Allow for minimum pump level and returning water.

Compare collapsible and rigid tanks by footprint, storage and maintenance access. Check the opening, pump and connections before choosing.

Clean the tank, pump and accessible fittings. Refill with a known water volume and check mixing, water level, pH and EC.
Read moreContainer volume does not tell you how many square metres you can feed. Water use, plant stage and dose determine consumption. Track A and B separately so you can compare packs on the same basis and avoid buying more than you can use in time.
An accessible nutrient reservoir helps you mix, measure and clean thoroughly. Keep nutrient residues separate from cleaning products. Follow our guide to cleaning and refilling a nutrient reservoir, then check the fresh solution.
