Humboldt Nutrients Verde 16-1-2

– made in USA

It’s Spanish for green. Lush green colors and vigorous growth are what you can expect with Verde. Used as a foliar spray or as a growth catalyst for hydroponic or soil crops, Verde can help keep plants healthy throughout their life cycle.

Verde is a premium growth supplement with 16% nitrogen, 1% available phosphorus, and 2% potassium, as well as iron, magnesium and other vital elements. This is a great blend for plants experiencing periods of accelerated growth.

Verde is a blend that contains high quality, cold pressed Ascophyllum nodosum seaweed, humic acid and pure Yucca extract. This unique product can increase root, stem and stalk structure, while boosting chlorophyll levels and protecting the health of your plant.

Use Verde in conjunction with Humboldt Nutrients base nutrients and additives for vigorous growth. This is the useful and balanced nitrogen additive you have been searching for.

(Not recommended for use in re-circulating hydroponic systems.)
