What is Hi-Nitrogen Kelp-Humic Blend 32-0-0?

GS Plant Foods Hi-Nitrogen Kelp-Humic Blend 32-0-0 is a premium, professional-grade liquid fertilizer specifically designed to correct nitrogen deficiencies and promote rapid lawn greening. Unlike standard synthetic fertilizers, this eco-friendly formula combines three forms of immediate-release nitrogen with organic kelp extract and humic acid. This unique blend supports both instant plant growth and long-term soil health, making it the ideal high-nitrogen fertilizer for all grass types, vegetable gardens, and hydroponic systems.

Key Ingredients & Active Properties

  • 32% Nitrogen (Three Forms): Provides highly soluble, easily absorbed nitrogen to fuel rapid leaf growth, resulting in dense, vibrant turf and foliage.

  • Organic Kelp: Delivers essential micronutrients, botanical extracts, and enzymes that enhance root vigor and increase plant resistance to environmental stress.

  • Humic Acid: Acts as a soil conditioner to improve soil structure, increase beneficial microbial activity, and unlock trapped nutrients for better root absorption.

Primary Benefits of Our 32-0-0 Liquid Fertilizer

  • Rapid Green-Up & Lawn Recovery: Visibly transforms dull, thinning, or yellowing grass into vibrant, healthy turf within just 3 to 7 days.

  • Enhanced Nutrient Efficiency: The synergistic combination of kelp and humic acid maximizes nitrogen uptake, significantly reducing fertilizer waste and preventing soil depletion.

  • Eco-Safe & Non-Toxic Formulation: Crafted with biodegradable, organic components that minimize environmental runoff, safely protecting local waterways.

  • No-Burn Guarantee: The perfectly balanced liquid formula ensures completely safe application with zero risk of root or leaf scorch when used according to package instructions.

  • Versatile Plant Application: Safe and highly effective for all lawn varieties (including Bermuda, Kentucky Bluegrass, and St. Augustine), as well as vegetables, flower beds, trees, indoor ornamentals, and advanced hydroponic setups.

Application Guide & Best Practices

  • Coverage Area: 1 quart of concentrate effectively treats upwards of 3,000 square feet of lawn or garden space.

  • Application Method: Dilute according to package instructions. Apply evenly across the target area using a standard hose-end sprayer or pump sprayer for optimal coverage.

  • Optimal Timing: Apply during the cooler hours of the day (early morning or late evening) to maximize foliar absorption and prevent rapid liquid evaporation.

  • Post-Application: Lightly irrigate the treated area immediately after spraying to water the vital nutrients directly into the root zone and prevent surface runoff.

  • Product Compatibility: Can be seamlessly tank-mixed with other GS Plant Foods products—such as Root Ruckus, Liquid Kelp, and Cal-Mag Extreme—to further amplify plant nutrient uptake.

Great cabin filter for 2019 Acura RDX
Size: 8.3" x 9.3" x 1.3"
When I have my car serviced at the Acura dealership, they routinely recommend that the cabin filter be replaced. As we all know, a dealership is going to charge an arm and a leg for a basic service. Therefore, I have been replacing the cabin air filter myself for the past few years. I like BOSCH products and when I found this filter on Amazon, I knew that was the one to purchase for my 2019 Acura RDX. The filter fits perfectly in its location in the glove box. It literally takes less than five minutes to swap out the old filter for the new. I will continue to use this product while I have the RDX.

Perfect fit, easy installation.
Size: 8.3" x 9.3" x 1.3"
This part fits perfectly. Directional flow is printed on the part however you need to confirm which way air flows in the actual air box. The easiest test is to run the a/c with the filter out, wet a finger, and stick in in the air box to see which side the air blows cold. Then just install this part in the air flow direction as printed on the part. I have not noticed a difference in air quality yet, however I imagine being a HEPA filter, this will do wonders keeping pollen out of the car. Installed this in a 2011 Honda CR-Z. Easy installation. Part looks high quality which is fitting for Bosch.

Great filter, but doesn't fit 2013 Honda Fit without modification
Size: 8.3" x 9.3" x 1.3"
Right off the bat: I don't have any airflow problems with this filter. It works great, the air is noticeably cleaner, and airflow has not been meaningfully reduced. However, it doesn't fit my air filter holder very well. The ' air filter holder' (a plastic tray that slides horizontally into the air flow system) has two plastic fringes on either side of the tray, which each have two small notches in them, a few inches apart from one another. This appears to act as a sort of 'key' by which you can gauge you are putting the filter in with the correct alignment. On an OEM filter, the slots line up with two strips of material that stretch across the length of the filter, which themselves rest within the slots. However, the slots don't line up with the strips on this filter. I had to cut the fringes so that the slots in them are wider, so the strips would fit in them. Without doing this, the filter wouldn't press down into the tray. Having done that, and the filter now rests flush in the tray, there are still marginal gaps around the perimeter of the filter. It's a millimeter or two too small for the tray, so there is some airflow around the filter. This could be rectified by wrapping insulation tape or something around the edge of the filter, or could be ignored if you're not super picky. I haven't added any wrapping to get an airtight seal, and even with that gap I still noticed that the air is way better. So ultimately, it didn't fit exactly, but it fits 90% of the way and, with some finagling, is a superior filter by any other measure.

Don't overlook this important bit of maintenance
Size: 8.3" x 9.3" x 1.3"
Cabin air filters get dirty and gross quicker than you realize. I recommend changing them twice a year. Bosch is a quality brand, very happy with it.

Better than Honda Cabin Filter for Allergies -
Size: 8.3" x 9.3" x 1.3"
Installation took all of 3 minutes. Noticeable improvement in air quality (less allergy response) since installation. Others mentioned a reduction in air flow but have not noticed a change. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Update (9/2020) Noticeable reduction in air flow. I have needed to increase the fan speed to make the cabin comfortable. I may be switching brands soon. I will pull the filter at 6 weeks and see if it is getting plugged (yikes). //////////// Update (10/2020) I pulled the Bosch filter expecting it to be plugged due to the lack of air flow. I was surprised to see it was clean. There were are few small pieces of stuff in the folds of the filter but only about 10 of them. I held the filter up to the light and then tapped it on white paper to see what would fall out. There was nothing present to explain the extreme loss of air flow. I have used Bosch cabin filters in my other vehicles (not HEPA) with great success. I was hoping to help the allergies of my family but having to run the fan on high to receive any airflow was more annoying than helpful. The noise was irritating and the air flow was still less than the Honda filter I removed. I purchased a new Honda cabin filter and our van is back to normal. I did not realize how much I missed the auto temperature setting. I was setting the temperature about 5 degrees below "normal" to try and keep the temperature consistent, and it was not during the hotter summer months. Unfortunately I am beyond the 30 day Amazon return window so I am not able to return the cabin air filter. :-( This is my first Amazon review that moved from 5 to 1.....
