FloraMicro is the calcium-and-micronutrient part of General Hydroponics' three-part FloraSeries feed, used alongside FloraGro and FloraBloom. Its 5-0-1 NPK carries nitrogen and calcium plus iron, manganese, boron and copper, so it anchors the mix in recirculating hydroponics and also works in potting mix and in-ground soil. It is a mineral (non-organic) liquid concentrate, not a standalone fertilizer, so it only makes sense as part of the trio. Users of the FloraSeries line value the predictable, well-documented mixing ratios; the trade-off is buying and measuring three bottles instead of one.
