Cutting Edge Solutions® Plant Amp™ Calcium Supplement — 32oz

Passive-Uptake Calcium for Cell Wall Strength, 32oz

Calcium can be sitting right in the reservoir and a crop can still show tip burn or blossom end rot, because the form calcium arrives in matters as much as the amount. Plant Amp supplies soluble calcium in a formulation built for passive uptake, so it moves into plant cells without competing against other cation nutrients for the same absorption pathway.

This 32oz size fits into a watering routine at every feeding, alongside base nutrients and other Cutting Edge Solutions supplements.

Key Features & Benefits

• Passive uptake optimization — calcium formulated for efficient passive absorption, reducing deficiency risk during high-demand production phases.
• Strengthens cell walls — calcium deposition in cell walls improves structural integrity, reducing tip burn, blossom end rot, and pathogen entry points.
• Supports enzyme & hormone function — activates metabolic enzymes and supports hormone signaling tied to vegetative and reproductive development.
• Heat & disease resistance — reinforced cell walls resist heat-stress collapse and pathogen penetration.
• Universal system compatibility — formulated for hydroponic, soilless, continuous feed, drain-to-waste, and soil programs.

Who Should Use This

Hydroponic and soilless growers running high-EC production programs, especially where tip burn or blossom end rot signal that base nutrient calcium is not keeping pace with crop demand, are the direct fit for this 32oz size.

About Cutting Edge Solutions

Frequently Asked Questions

Can I use Plant Amp with other calcium-magnesium supplements?

Yes, Plant Amp provides calcium specifically and can be stacked with a magnesium-sulfur supplement for a complete secondary nutrient program. Avoid over-supplementing calcium relative to magnesium, and maintain a Ca:Mg ratio appropriate for the crop and growth stage.

How does passive calcium uptake differ from active uptake?

Passive uptake moves calcium along water potential gradients through the transpiration stream, independent of energy expenditure, while active uptake requires metabolic energy. Plant Amp is formulated to favor the passive pathway, making calcium available even when transpiration rates are lower during lights-off or high-humidity conditions.

When during feeding should Plant Amp be added?

Add Plant Amp to the reservoir after base nutrients have been diluted, applying it at every watering as part of a complete nutrient program. Follow the current feeding schedule for exact dosing by growth stage.

Is Plant Amp compatible with organic nutrient programs?

Plant Amp is a synthetic soluble calcium supplement designed for hydroponic and soilless applications. For certified organic programs, verify compliance with the certifier's approved input list before use.
