Pro Powders Seaweed 16-16 Seaweed Extract Powder - 1 lb

Water-Soluble Seaweed Extract for Flexible Feeding - 1 lb

Growers who want a plant supplement that works across irrigation, spray and drench routines often end up buying several products. This seaweed extract powder is derived from Ascophyllum nodosum brown seaweed, is cold-processed, and dissolves completely in water, so one product covers fertigation, foliar, soil drench and top watering. The analysis includes alginic acid, mannitol, amino acids and soluble potash.

The 1 lb size suits hobbyists, trial runs and small indoor systems. It lets you test the extract in your own nutrient program before committing to larger quantities.
