Plagron nutrients come in a line for every growing medium: mineral Terra Grow and Terra Bloom and natural Alga Grow and Alga Bloom for soil, Cocos A+B for coco and Hydro A+B for hydroponics. Additives such as Power Roots, Pure Zym, Green Sensation and PK 13/14 complete the schedule. Reference pH: soil 6.0–7.0, coco and hydro 5.5–6.5.
The Plagron feeding schedule combines the base of your line with additives for each stage:
| Product | Role | Stage |
|---|---|---|
| Terra Grow | mineral soil base, growth | vegetative |
| Terra Bloom | mineral soil base, flowering | flowering |
| Alga Grow | natural soil base, growth | vegetative |
| Alga Bloom | natural soil base, flowering | flowering |
| Cocos A+B | two-part coco base | whole cycle |
| Hydro A+B | two-part hydro base | whole cycle |
| Power Roots | root stimulator | growth and early flowering |
| Pure Zym | enzymes for the growing medium | whole cycle |
| Sugar Royal | amino acid stimulant | growth and flowering |
| Silic Rock | silicon for stronger tissue | whole cycle |
| Green Sensation | combined bloom booster | last weeks of flowering |
| PK 13/14 | concentrated phosphorus and potassium | about one week in mid-flowering |
| Power Buds | bloom booster for the natural line | flowering |
| Bat Guano | solid organic guano-based feed, rich in phosphorus | as per the product sheet |
Terra and Alga are both soil lines: Terra is mineral, acts fast and is easy to control by EC; Alga is the natural line, whose nutrients are released more gradually. Cocos A+B is for coco coir and Hydro A+B for hydroponic systems: add A and B to the water one at a time, stirring in between. As a bloom booster you normally use either Green Sensation or PK 13/14, as the schedule indicates.
The doses in ml per litre and the weeks come from the official Plagron schedule for your line. Start with a lower dose and increase gradually, staying within the reference values: EC 0.4–0.8 mS/cm for seedlings and cuttings, 0.8–1.6 in the vegetative stage and 1.2–2.0 in flowering. The brand's soils and coco are among the Plagron growing media, the comparison with other brands is on the grow nutrients page and the meters are among the pH and EC meters.

Pick the schedule for your line (Terra, Alga, Cocos or Hydro), read the dose of each product in ml per litre for the current week and add it to the water. Then check EC and pH.
Both are designed for soil: Terra is mineral and acts faster, while Alga is the natural line and feeds the plant more gradually through soil life.
During the vegetative stage and early flowering, when the plant builds most of its roots.
They are two alternative bloom boosters: Green Sensation is a combined product for the last weeks of flowering, PK 13/14 a targeted boost lasting about one week. As a rule you use only one of them, following the schedule.
