Pro Powders Humic + 70/5 Humic & Fulvic Acid Powder - 3 lb

Humic and Fulvic Support for Stronger Root Zones - 3 lb

Compacted media and nutrients that wash through before roots use them slow down vegetative growth and flowering. This leonardite-derived powder combines humic acid, fulvic acid and soluble potash to improve soil structure and help the root zone hold nutrients. It dissolves fully in water, so you can mix it into the same solution you already feed with.

The 3 lb size suits regular indoor growers and small to mid-size operations that want to run a humic program across several feeding cycles. Smaller gardens can use it to trial the product before scaling up.

Key Features & Benefits

• Humic and fulvic blend — supports soil structure and nutrient retention.
• Soluble potash — supplies potassium alongside the organic acids.
• Water-soluble powder — mixes into feed water for even delivery.
• Four application methods — use it in fertigation, foliar sprays, soil drenches or top watering.
• Leonardite source — a mineral-derived organic material.

Who Should Use Pro Powders Humic + 70/5

Growers who condition soil or soilless media, support transplants, or want to improve how plants use their fertilizer. It fits both home gardeners and licensed commercial growers running irrigation systems.
