The bulking additive, in a certified organic form
OG Organics Big Bud is the certified organic version of Advanced Nutrients' best known bulking additive. It supplies organic phosphorus and potassium with amino acids through the sizing weeks, for growers who do not want a mineral PK in an otherwise organic programme.
Key Benefits
- Organic bulking - the one product most organic programmes are missing
- Amino acids alongside the PK - supports sugar transport into the flower
- Certified organic - keeps the whole schedule certifiable
- Mid-flower window - dosed where density is actually decided
- Works with any organic base - not tied to Iguana Juice
Going organic and losing the bulking stage
Organic growers usually have a base and a root product and nothing for the sizing weeks, so the plant flowers cleanly and finishes light. Airy buds from a missing mid-flower PK is the commonest weakness in an organic schedule.
How to Use
- Weeks 2 to 5 of flower: 4 ml per litre at every feed
- Peak sizing: up to 6 ml per litre if the plant is feeding hard
- Taper: stop about a fortnight before harvest
- Reservoir: mix fresh - it carries organic matter
- Media: soil, coco and hydroponics
