Alpha Plus

Black Earth leaf logo small

Alpha Plus is derived from humalite, a highly concentrated source of humic acid found only in Alberta, Canada. Humalite contains a unique profile of functional carbon groups, unmatched by other source materials.

The extraction method used to produce Alpha Plus isolates the fulvic acids and most bioactive humic acids contained within this unique source material. The result is a potent liquid humate that will give your crop the boost it needs.

Sizes available: 265 gal (1000L) and 5 gal (18.9L)
