One kelp-based additive for potassium top-ups, transplants and seed starts Athena Stack is a natural plant nutrient made from kelp extract that gives plants the tools to reach their full genetic potential across several jobs in one bottle. As a foliar spray it corrects minor potassium deficiencies; at transplant it reduces stress on vulnerable young roots; and as a seed soak it supports germination and early vigour. It contains organic ingredients, so expect some separation in storage - shake well before use. Fixing minor potassium deficiencies and transplant stress Potassium shortfalls and the stress of transplanting or germinating can quietly hold back growth even when the rest of your feed is dialled in. Stack's kelp base addresses minor potassium deficiencies as a foliar, and reduces transplant stress when used as a root soak or watered in. Key Benefits Corrects minor potassium deficiencies - effective as a weekly foliar spray Reduces transplant stress - improves vigour as a root soak or post-transplant drench Supports germination - may lift germination rates and early vigour as a seed treatment Kelp-extract based - contains organic ingredients; shake well before use Irrigation-safe - suitable for fertigation as well as foliar application How to Use General window: the final week of veg up to week 3-5 of flower, stopping once vertical stretch has finished. That is the whole period Stack is useful in Foliar spray: mix 7ml per gallon of water and spray thoroughly once weekly through that window. Spray with lights off and let foliage dry before the lights return Transplant: mix 2ml per gallon and bare-root soak for 30-60 seconds before transplanting, or water in afterwards Seed treatment: mix 4ml per gallon and soak seed for 1-2 minutes before planting When to stop: once the plant has stopped stretching upward. There is nothing to gain from carrying on past that point Technical Specifications Type: kelp-extract vegetative supplement Range: Athena Blended Line Uses: foliar, transplant soak, seed treatment General window: last week of veg to flower week 3-5 Foliar rate: 7ml per gallon, weekly Transplant rate: 2ml per gallon Seed rate: 4ml per gallon Composition: organic ingredients, may separate - shake before use Feed Chart Athena Stack (Blended Line) · foliar, transplant soak and seed treatment Application Per 1 L Per 10 L Foliar spray, weekly, lights off 1.85 ml 18.5 ml Transplant soak or post-transplant drench 0.53 ml 5.3 ml Seed soak, 1 to 2 minutes before planting 1.06 ml 10.6 ml Note — Athena publish these as 7, 2 and 4 ml per US gallon; the figures above are those rates converted at 3.785 litres to the gallon.
