I’m always on the lookout for the next best thing to try in my lawn. There’s been lots of buzz about the N-Ext line of products, which include RGS Bio-Stimulant, Micro Greene 0-0-2, and Green Punch 18-0-1. I was willing to give these a shot until some guys in a New England Lawn Care group started talking about cheaper alternatives – specifically Kelp4Less Extreme Blend and Organic Humic Acid.
So I decided to give it a shot. With the coupon codes, I spent roughly $30 for these popular supplements, which included fast free shipping. The packaging was super tight. I first opened the large USPS envelope, to find another smaller USPS envelope with the product tightly sealed inside. The plastic bag of both products were in a zip-top resealable bag that first required scissors to open. I mention this in detail because it shows they take great pride and effort in ensuring that the products arrive to your doorstep or mailbox safely, and not busted open.
The Extreme Blend has a nice but potent smell. You can literally see all of the different specs of ingredients throughout. This is one of Kelp4Less’ most popular products – and no wonder why. It contains a blend of sea kelp, humic acid, fulvic acid, and amino acids which aids the plant during the grow and bloom stages, and helps promotes photosynthesis. The standard fertilizer analysis (per 100 pounds) of ExtremeBlend is 12-0-6. With the little bit of Nitrogen, I do notice my back lawn in particular growing very fast – faster than years past.

The Organic Humic Acid has a bright charcoal appearance. There were some clumps of Extreme Blend, but they broke apart easily. The standard fertilizer analysis (per 100 pounds) of this Humic Acid is 0-0-4. As stated on their website, this is great for:
Plant growth stimulant. Improves plant immunity, metabolism, root development. Aids the plant’s ability to better manage heat, drought, cold, disease, insects and other stresses. Aid in plant yields, stem strength. Stimulates soil micro-organisms to promote humus in the soil.
The mixture, or ratios, that I use are based on 1,000 ft.2
Extreme Blend Ratio & Usage:
- 1 Tablespoon = 10 grams by weight
- 454 g = 1 lb
- 1 Tablespoon in 1 gallon of water
- Total yield: Roughly 1 acre at a maintenance rate per pound
Humic Acid Ratio:
- Backpack sprayer: 1 tablespoon of humic per gallon of water
- The company recommended 1/2 teaspoon per gallon, so I went a bit overboard here. However I did plan these applications before rain. So I was able to get some foliar feedings, while ensuring it was diluted/watered-in within 24 hours.
- Hose-end sprayer (Chameleon): 1 Tablespoon of humic into the chamber, filled with water (30 oz.), set the dial to 4, and spread over 1,000 ft.2
The Extreme Blend mixed and dissolved nicely. The humic acid, however, took a lot more shaking and soaking. So what I did was, the night before, mix my entire solution in a gallon water just with warm tap water. Shook-shook-shook, then stored in my garage refrigerator. This made a world of difference – there was hardly any granulars leftover on the bottom of the jug. Then for good measure, used my electric drill with paint mixer attachment and never had any issues with product clogging my sprayer.
Here’s a few pics as my front lawn comes out of dormancy.

- Picture2: April 3, 2019. First application of Extreme Blend goes down.
- Picture3: April 13, 2019. First application of humic acid and second app of Extreme Blend.
Here are the pictures of the dead areas cause by snow and snow melt. The area next to the tree was from the snowblower dumping the big pile from the driveway; along the house was from shoveling the walkway up to our front door.
April 13 was the first application. Look at the results in just two days! From there I did spoon feedings weekly, and incorporated some Calcium Carbonate. Click on the images to begin slideshow and see dates.
As they mentioned several times in their videos, the packaging is discrete and very secure. Here are some pictures of my products as I received them in the mail:
Overall, I noticed that my lawn has greened-up quicker with less fertilizer. I also see that my lawn has stayed a dark green much longer than seasons past. In the image gallery above, I had a big patch of dead area where my snowblower dumped the snow from the driveway. After spoon feeding the area weekly with both ExtremeBlend and Humic Acid, the area bounced back, thickened up, and is now blended-in with the rest of the front yard.
I will update this post sometime in July or August as I continue to use the Humic Acid specifically throughout the summer months. I plan on stopping all standard fertilizer applications – including Milorganite/Bay State – for these two months, and just supplement Kelp4Less products weekly or biweekly, depending on irrigation.
Overall, these products receive an A+ from me. These dry, water soluble products are an awesome, cheaper alternative to some more popular brands as mentioned above. Those other products are pre-mixed with water, and they’re not concentrated nearly enough to cover the amount of square footage as Kelp4Less – especially at the price of roughly $20/pound.

Awesome review. I can’t wait to try this out on my lawn this year.
Thanks, Nick! Can’t go wrong with this or the Green Lawn & Turf. Also stay tuned for 6 new lawn care products this year. Keep me posted on your progress!
Mark, I have my extreme blend arriving on Monday. I can’t wait to see how it works on my JG Black Beauty I used last as my Fall re-seed. Thanks for turning me on to Kelp4less. Keith – Charlotte, NC
Hi Keith. That’s great! Let me know if you have any questions – keep me posted on how you make out.
I Applied Howard Johnsons Dimension .27G pre emergent around April 1. I just purchased 2 lbs of both Extreme and Green Lawn and Turf. Do I need to wait to apply those? Do I need to wait between applying Green Lawn and Turf and Extreme? Which should go down first if so?
Hi Rob. You don’t have to wait – these are fine to apply pretty much any time. I’d go with Extreme Blend first then Green Lawn & Turf 2-4 weeks later. It contains molasses and iron which will be beneficial as things warm up.
And if you have any ornamentals, I’d definitely use Extreme Blend at low rates as a root soak once a week. I applied this to my azalea and hydrangea last year and they exploded.
Just got this for the “2 for 1” Deal, I have already started applying Green Turf this season, what do you think about applying this once a month during the summer? I’m in the Mid-Atlantic. Thanks!
Hi Peter – good time to buy! Yes, I think applying this even every 2 weeks is fine as long as your turf is not under too much stress, or drought/dormant. I continue to apply Effort Lush throughout the hot weather. The kelp, humic, and aminos all help during stressful conditions. I prefer to apply in the early evening when the sun is setting and water in the following morning.
I too am incorporating much of kelp4less into my lawn care program. Thank you for your tips and advice! Question, would you equate kelp4less summer survival to LCN stress blend?
Thanks, Jason! I appreciate the feedback.
I don’t think I’d equate the two since the stress blend is a 7-0-20 granular. I’d probably think of the Summer Survival as a mix of Sea-K and Humic12 with the addition of potassium sulfate. I do like adding calcium hydroxide to the mix. And a bonus would also be some molasses powder. I applied this to my stressed lawn and saw a noticeable reaction.
I just want to say, man – impressive. 6 minute response to a stranger’s question. I’ve read through many of your reviews, recommendations, and comments from other visitors. Very well done, and much appreciated. Thanks again for all you do for the homeowner lawn community!
You’re welcome! I appreciate the comments and questions and support.
