Description
A hard signal at the flip, in powder form
Bud Blood is a soluble powder used in the first week of flower to force the transition. It is very heavily weighted to phosphorus and potassium and is deliberately short-lived - it is a signal rather than a feed.
Key Benefits
- Powder concentration - a very small dose per litre, so the container lasts
- Forces the transition - a hard, early PK signal moves the plant out of vegetative mode
- Only used for a week - its whole job is the first seven days
- Any base feed - works with the Advanced Nutrients programme or another
- Follow with a bulking additive - Bud Blood starts flowering, it does not fill it
A plant that will not stop growing after the flip
Some varieties and some feeding schedules keep a plant in vegetative mode well past the light change, so it stretches hard and sets late. A strong early phosphorus and potassium signal shortens that, and the difference shows in canopy height as much as in yield.
How to Use
- Week 1 of flower only: 0.5 g per litre at every feed
- Dissolving: mix into warm water and stir until clear before it goes into the reservoir
- Stop after week 1: continuing does nothing useful and adds unnecessary EC
- Follow with: Big Bud from week 2
- Media: soil, coco and hydroponics
