Humic and fulvic acids from leonardite, in one product
Ancient Earth supplies humic and fulvic acids derived from leonardite. The two work at different scales - humic conditions the medium and holds nutrients on exchange sites, fulvic is small enough to carry minerals into the plant - and this product covers both.
Key Benefits
- Humic and fulvic together - the two halves of the job in one addition
- Improves uptake at the same EC - more of the feed you already pay for gets used
- Conditions the medium - better structure and exchange capacity, especially in coco and reused soil
- Certified organic - fits an organic programme
- Works with any base feed - mineral or organic
Feeding harder and getting nothing back
When growth stalls the instinct is to raise EC, which usually ends in salt build-up and poor nutrient uptake. Humic and fulvic acids attack it from the other side, making the existing solution more available and holding it where roots can reach it.
How to Use
- Whole cycle: 2 ml per litre at every feed
- Reused medium: 4 ml per litre for the first two feeds of a second run
- Foliar: 1 ml per litre, lights off
- With beneficials: pairs well with a microbial inoculant
- Media: soil, coco and hydroponics at a reduced rate
