Athena Pro Line

What is Athena Pro Line

Athena Pro Line is the powdered version of the Athena program, designed for large grows, drain-to-waste drip and fertigation systems. The formulas are mineral, low in heavy metals and 100% soluble at room temperature: no sediment, and no clogged injectors, venturis or drippers.

• Athena Pro Core (14-0-0): the base for the whole run. Calcium nitrate with chelated iron, copper, manganese and zinc (EDTA), boric acid and sodium molybdate.
• Athena Pro Grow (2-8-20): for veg, always with Pro Core. Potassium phosphate, potassium nitrate, potassium sulfate, magnesium sulfate and iron DTPA.
• Athena Pro Bloom (0-12-24): for flower, always with Pro Core. Monopotassium phosphate, potassium sulfate, magnesium sulfate and iron DTPA.
• Athena Pro PK: phosphorus-potassium booster for flower. Dose it according to its label and check the final EC.
• Athena Pro Balance: pH up designed for dosers such as GroLab, Dosatron or NetaFlex.

The Athena Pro ratio: 0.6 Core to 1 Grow or Bloom

The official chart uses 11.4 g of Pro Core and 19 g of Pro Grow or Pro Bloom per 10 litres of water, at EC 3.0 for the whole run. In the final week of flower it drops to 4 g of Core and 6.6 g of Bloom (EC 1.5). Always weigh on a scale, because measuring powder by volume throws the EC off. And never mix the bags dry or in the same concentrate.

Making the stock concentrate

Athena recommends dissolving each powder separately in its own stock tank, then dosing the reservoir or injector from there. Their reference is about 240 g per litre of water, and never more than 300 g per litre. Fill the tank halfway, add the powder slowly while stirring, top up to the mark and agitate until everything has dissolved.

How much you’ll use per run

Following the official chart (4 weeks veg, 9 weeks flower), for every 100 litres of solution per week you’ll use about 1.41 kg of Pro Core, 0.76 kg of Pro Grow and 1.59 kg of Pro Bloom.

Athena Pro or Athena Blended?

Pro pays off with a doser, drain-to-waste drip and large volumes. If you hand-mix less than 100 litres a week, the Athena Blended range is easier: it’s liquid and you don’t need a scale.
