Product Overview

Neptune's Harvest Seaweed Plant Food is an organic product derived from seaweed that grows on the cold floor of the North Atlantic. This plant food is packed with more than 60 macro and micro nutrients, and amino acids. Neptune's Harvest Seaweed Plant Food is a natural source of plant growth promoting hormones (cytokinins, giberrellins, and auxims) that promote vigorous plant growth and development all while enhancing color. The seaweed in Neptune's Harvest Seaweed Plant Food makes plants hardier and more resistant to less than ideal conditions like lack of moisture, extreme heat, and early frost. When used to germinate seeds Neptune's Harvest Seaweed Plant Food promotes the quick development of healthy root systems thereby accelerating the germination process.

Use in conjunction with Neptune's Harvest Organic Hydrolyzed Fish Fertilizer for best results.

    Was glad to buy this from you. The product isn't carried where I live, the shipping was free and the price was fair. Saved me a long trip.

Questions & Answers

Have a question about this product?
I'm was told to add Neptune's Harvest Seaweed Plant Food to my 1,600 gal Aquaponic fish tank.

Not such how much to use, I added 32 oz. 6 days ago. Not sure what my water is testing at because I'm still waiting for my test kit to be mail to me.

The product label for Neptune's Harvest Seaweed Plant Food does not list that it can be appled to fish tanks so we are unable to provide dilution instructions.  We would recommend contacting the manufacturer directly to ensure the product can be used in this way and for instructions if so, Neptune's Harvest can be reached at 1-800-259-4769.
