Description
Please note - the Athena Stack in this kit is decanted: Athena no longer supply Stack in this bottle size in the UK, so it is hand-decanted in-store from Athena's own larger branded bottle. It is genuine Athena Stack, measured out into the quantity this kit needs, with none left over sitting unused in your cupboard.
Use Athena IPW and Stack together as foliar spray; combining both products drives the quality and overall vigour of the plant while reducing pests and pathogens. it also promotes tighter internodal spacing, node development and the plant's taste profile.
Note: Athena® IPW may also be familiar to growers as Athena® IPM. IPW is the international-market version, branded as Integrated Plant Wash to meet differing regulatory and product-classification requirements outside the USA.
Less waste, more yield. Trust The Program.
The Athena Stack is decanted from 1 gallon bottle (32oz bottles no longer available in UK!)
