Flora-1 is a PK flowering additive designed specifically for 1-part hydroponic nutrients.  It enables 1-parts to perform just as effectively as the best 2-part nutrients.

FLORA-1:  PK flowering additive for 1-part nutrients

1-part* nutrient formulations are structured differently to 2-part nutrients and consequently require a specific PK additives to guarantee their performance.  Flora-1 contains a carefully balanced combination of potassium and phosphorus with the addition of sulfate and iron:

  • Stimulates vigorous floral blooms.
  • Aids in the production of amino acids.
  • Improves tolerance to harsh grow room conditions and helps prevent common symptoms such as yellowing, necrosis and leaf curl.
  • Unlike regular PK additives, Flora-1 helps lock pH below 6.5 by improving the nutrient’s pH buffering by over 500%.  This prevents pH related deficiency symptoms, even when hard water or alkaline additives are used.

pH stability?  pH problems are common during flowering and will negatively impact yields.   ‘Flora-1’ will actually lock pH below 6.5 when growing in coco coir and soil, even when hard water or alkaline additives are used.  This prevents a multitude of potential growth problems such as leaf leaf curl, stunted growth and withered fruit-set.  Note, in many cases flowering additives will cause pH to rise well above 6.5, regardless of how good the water quality is.

“Flora-1 has massively improved the performance of the 1-part nutrients that we offer our growers. Yields were normally always sub standard to 2-part nutrients. With Flora-1 the growers are seeing lush healthy foliage with no signs of yellowing or stalling and the yields are more than comparable.” (Grow Shop owner)
Powering the flower (article)

1. Use high pressure sodium (HPS) lamps, rich in the yellow, orange and red parts of the lighting spectrum, to drive the flowering stage. Many growers retain a 50 / 50 mix of metal halide and high pressure sodium lamps or use dual arc lamps for a fuller spectrum and a little ultraviolet (UV) to promote the production of more essential oils. Other emerging technologies such as double-ended lamps offer higher performance over a longer period.

2. If you are growing in a regular, ventilated grow room, consider upping the air-exchange rate. Flowering plants tend to prefer a gradual lowering of relative humidity to around 40 – 45 percent. Also, carbon dioxide consumption is reaching its peak and is therefore often the weakest link.

3.  Don’t get complacent with bugs or diseases such as powdery mildew! Savvy growers periodically release beneficial insects (harmless bugs that feed on the ones that do the damage!) into their garden regardless of whether a pest has been identified. Regularly check both sides of foliage on all your plants—especially those that sometimes get overlooked in the corner.
