When CaFe Mag 5 lb Belongs in the Programme
Iron is usually the first micronutrient to go missing when a reservoir drifts up. Availability falls away as pH climbs, so a tank sitting above 6.5 can hold plenty of iron and still leave the plant short. Coco and rockwool on hard water are where it shows up most. This carries 4.00% iron against 1.75% calcium and 1.50% magnesium, from greensand, magnesium, an amino acid complex and colloidal clay. Micronizing keeps it in suspension, so it reaches the root zone rather than the bottom of the tank.
Working a Calcium Magnesium Iron Powder Into a Feed
Watered in weekly, the mild band is an eighth to a quarter teaspoon per gallon. Strong is a half to one teaspoon, and heavy runs to a tablespoon. Top dressing is a half to two teaspoons per cubic foot every two to four weeks. Move up a band only when the leaf says so. A 5 lb bag is the size for a room you run continuously rather than a tent you fill twice a year. At the mild rate it outlasts the 1 lb bag by a long way. That is where most rooms settle once the deficiency is corrected. Keep the bag sealed between fills. Micronized powder that takes up moisture clumps, and clumped powder does not go into suspension cleanly.
Key Features
- Iron leads at 4.00%: Against 1.75% calcium and 1.50% magnesium, so it is an iron-first supplement.
- Aimed at the pH problem: Iron availability falls as a reservoir climbs, even when iron is present.
- Coco and rockwool on hard water: The media and water combination where iron goes short first.
- Greensand and amino acid complex: How the iron is carried, with magnesium and colloidal clay alongside.
- Micronized for suspension: It reaches the root zone instead of settling in the bottom of the tank.
- Three weekly dose bands: An eighth of a teaspoon a gallon at the mild end, a tablespoon at the heavy.
- Top dress by the cubic foot: Half to two teaspoons, every two to four weeks, worked into the medium.
- Room-sized bag: 5 lb suits a room in continuous production rather than a seasonal tent.
- Store it sealed: Powder that picks up moisture clumps, and clumps will not suspend cleanly.
