General Hydroponics FloraMicro 5-0-1 - 55gal

Calcium and Micronutrient Leg of the Flora Series System, 55gal

Blending a hydroponic feeding program from raw salts means calculating calcium and micronutrient ratios without a safety net, and a miscalculation there can lock out other elements before you notice. General Hydroponics FloraMicro 5-0-1 removes that guesswork, supplying nitrogen, calcium, and a full trace-element package as the micro-element leg of the Flora Series building-block system.

This 55gal drum is sized for commercial operations that batch-mix large reservoirs and need a steady supply of the micro component on hand.

Key Features & Benefits

• Nitrogen, Calcium & Trace Elements — supplies the micro-element portion of the Flora Series profile in one liquid concentrate
• Flora Series Building-Block System — combines with FloraGro and FloraBloom for a fully adjustable feeding program
• Mix-First Formula — added to reservoir water before FloraGro or FloraBloom to avoid nutrient lockout
• Liquid Concentrate Format — dissolves quickly for consistent, repeatable mixing at any batch size

Who Should Use FloraMicro

Hydroponic and soilless growers running the GH Flora Series 3-part system who need a dedicated calcium and micronutrient component will find FloraMicro built as that first building block.

Frequently Asked Questions

What does FloraMicro supply that FloraGro and FloraBloom don't?

FloraMicro carries the nitrogen, calcium, and trace-element portion of the Flora Series profile, filling in the calcium and micronutrient levels the other two components leave out. Without it, a FloraGro-and-FloraBloom-only mix would run short on calcium and several trace elements.

How do I mix FloraMicro with the rest of the Flora Series?

Add FloraMicro to your reservoir water first, before FloraGro or FloraBloom, and let it fully dissolve. Adding the calcium-heavy FloraMicro after the other two concentrates raises the risk of nutrient lockout in a concentrated mixing tank.

What growth stages does FloraMicro cover?

It runs across the entire growth cycle, from early vegetative growth through flowering, with the mixing ratio adjusted at each stage. The Flora Series feeding chart sets the specific ratio of FloraMicro to FloraGro and FloraBloom for each week.

Can I use FloraMicro by itself without FloraGro and FloraBloom?

No, it is designed as one leg of a three-part building-block system rather than a stand-alone fertilizer. Used alone, it would leave a plant short on the phosphorus and potassium that FloraGro and FloraBloom supply.

Which FloraMicro size fits a small home grow?

The 16oz and 32oz bottles suit growers who are new to the Flora Series or running a small personal grow with limited weekly volume. Larger operations typically move up to the 1gal through 275gal Tote sizes as their reservoir volume grows.
