The Athena Pro Line Starter Mix Kit is the easiest way into the Pro Line. It contains pre-weighed 0.9 kg pouches of Pro Line Grow, Pro Line Bloom and Pro Line Core, plus a 3.78 L (1 US gallon) mixing jug. One pouch into the jug, top up with water and shake — you've made an accurate stock concentrate without weighing a single gram.
Why concentrates beat weighing powder
Weighing small amounts of powder straight into a reservoir is where most Pro Line errors start. A few grams out either way changes the mineral ratio, and batch-to-batch variation shows up as deficiencies. Athena's method is to mix a concentrate first, then measure that into your tank. The kit does the weighing for you: each 0.9 kg (2 lb) pouch matched to the 1 US gallon jug gives you Athena's recommended 2 lb-per-gallon concentrate every time.
What's in the box
One pouch each of Pro Line Grow, Pro Line Bloom and Pro Line Core, and one 3.78 L mixing jug. When the pouches run out, the 4.53 kg Pro Line boxes come as 5 inner pouches of the same size — refills for the same jug.

FAQ
Is this enough to run a full cycle?
It depends on the size of the room and how much you feed. The kit is designed to get you started on the Pro Line accurately; larger grows move to the 4.53 kg or 11.34 kg boxes.
Do I need anything else?
For pH, Pro Line Balance is the Pro Line's pH up. For the final 3 weeks of flower, Athena's procedure replaces Core with Pro Line Fade.
Can I mix the three pouches together?
No. Each part is mixed into its own concentrate. Combining them as powders or concentrates causes them to react before they reach the water.
Can I use the Pro Line in DWC?
Athena publishes no DWC procedure for the Pro Line. For deep water culture, the Blended Line is the one to use.
