Description
Fulvic acid on its own, without a carrier blend
RAW Full Up is a 100% water-soluble fulvic acid biostimulant that improves nutrient uptake, stress resilience and overall feed efficiency across soil, hydro and foliar applications. Fulvic acid's small molecular size means it moves readily through any growing medium and chelates minerals so they stay plant-available rather than binding out. Made by NPK Industries as part of the RAW soluble range, it is a clean, dry humate-derived powder with no fillers, stabilisers or added water, so it mixes instantly into the reservoir, the watering can or a foliar spray.
It is designed to be paired with RAW Humic Acid and RAW Kelp as part of a wider biostimulant programme, each covering a different part of the same job — fulvic acid for mobility and uptake, humic acid for anchoring and buffering, kelp for hormonal support. RAW points to Virginia Tech research on a 5:2 humic-to-kelp ratio as the basis for running them together.
Key Benefits
- 100% water-soluble fulvic acid — no fillers, stabilisers or added water, so it dissolves completely
- Improves nutrient uptake efficiency by keeping minerals mobile and available in the feed
- Supports stress resilience — its chelating action improves the supply of the trace elements that activate the plant's protective enzymes
- Suits soil, hydro and foliar applications, with separate maker rates for solution feeding and for mixing into soil
- Pairs with RAW Humic Acid and RAW Kelp for a complete humic, fulvic and seaweed programme
- Tiny doses — a level 1/8 to 1/4 tsp treats a US gallon (3.8 L) of feed
Poor nutrient uptake despite a full feed
Plants can sit in a well-mixed reservoir and still show deficiency symptoms when minerals react with each other, bind to the medium or move too slowly to the roots — a familiar story with hard water, high-EC feeds and re-used substrates. Fulvic acid is a natural chelating agent: it holds mineral ions loosely enough to hand them over on demand, which keeps iron, manganese, zinc and the other trace elements available for nutrient uptake and healthy root development instead of locked out.
How to Use
- Add to the reservoir or foliar spray solution at every application
- Reservoir and irrigation: 1/8 to 1/4 tsp per US gallon (3.8 L) — roughly 0.16–0.33 ml of powder per litre — applied as needed
- Weekly programme: RAW's own chart brings Full Up in at 1/16 tsp per gallon in week 2 of growth, uses 1/8 tsp in growth weeks 3–4 and flowering weeks 1–2, and peaks at 1/4 tsp in flowering weeks 3–6
- Soil: mix 1/4 to 1/2 tsp per US gallon (3.8 L) of soil through the root zone
- Foliar: RAW lists Full Up for foliar use — start at the lower solution rate
- Combine with RAW Humic Acid for a full humic/fulvic programme
- pH: check pH before feeding — RAW aims for 6.0

Frequently Asked Questions
What is the difference between RAW Full Up and RAW Humic Acid?
Both are humic substances, but Full Up is the fulvic fraction — small molecules that move easily through the medium and keep minerals mobile — while RAW Humic Acid carries 59% humic acids from leonardite, larger molecules that anchor in the root zone and buffer pH. RAW designs the two to be used together.
Can I use Full Up in hydroponics and coco?
Yes. It is a 100% water-soluble powder with no fillers, made for reservoir feeding in hydro and coco as well as soil and foliar use, and it works alongside any base nutrient.
When in the cycle should I use it?
Through growth and flowering. RAW's weekly chart starts it in the second week of growth and runs it to week 7 of flowering, with the highest rate — 1/4 tsp per gallon — in flowering weeks 3 to 6.
How do I dose a big tank?
Scale the teaspoon rate up: 1/4 tsp per US gallon is about 3.3 ml of powder per 10 L, or a little over two level tablespoons per 100 L. Use a dry measuring spoon and level it off.
