Pro Powders Humic + 70/5 Humic & Fulvic Acid Powder - 20 lbs

Water-Soluble Humic and Fulvic Feed for Stronger Root Zones - 20 lbs

Nutrients that wash through the root zone waste fertilizer and leave plants short of what they need. This leonardite-derived powder combines humic acid, fulvic acid and soluble potash to improve soil structure, hold nutrients in the root zone and support root development. The distributor lists it as fully water soluble, so it can go through fertigation, foliar, drench or top-watering routines.

The 20 lb bag suits growers who condition soil or support transplants on a regular schedule, and commercial or larger indoor operations that run automated irrigation. Smaller sizes are listed by the distributor for trial use.

Frequently Asked Questions

Q: How do I apply it?
A: Premix the powder into water before adding other nutrients. You can then apply it through fertigation, as a foliar spray, as a soil drench or by top watering. Adjust pH as needed after mixing.

Q: What pH should my solution be?
A: Keep the nutrient solution pH between 5.8 and 6.5. Check and adjust after mixing, because the powder itself is alkaline.

Q: Can I mix it with other products?
A: Run a compatibility test, also called a jar test, before mixing it with other products. Mix a small batch in a clear jar and check for clumping or settling before treating plants.

Q: What is leonardite?
A: Leonardite is a naturally oxidized organic material rich in humic substances. It is the source material for this powder.

Q: Does it replace fertilizer?
A: No. Use it as part of a complete nutrient program, where it supports nutrient retention and root-zone conditions.

Q: How should I handle and store it?
A: Avoid breathing dust, work in a ventilated area, and wear gloves and eye protection. The label warns it causes skin and eye irritation and is harmful if swallowed or inhaled. Store it sealed in a cool, dry place away from children and pets.
