General Hydroponics FloraBloom - 1 Gal

Bloom-Stage Phosphorus and Potassium Feed - 1 Gal

When plants move from vegetative growth into flowering, their nutritional needs change and a vegetative-stage feed stops being enough. FloraBloom supplies phosphorus, potassium, magnesium and sulfur to support flower and fruit development, and it shifts a FloraSeries program toward reproductive growth. The label lists 5.0% available phosphate (P2O5) and 4.0% soluble potash (K2O).

The 1 Gal bottle suits home gardeners and small to mid-size indoor growers who want to run a full bloom cycle without buying in bulk. It is also a practical size for trying the FloraSeries system before committing to larger volumes.
