Product Description:
Humic12 liquid humic acid product is an excellent addition to any fertilizer program for correcting soil issues. Humic acid is essentially the final remains of organic matter, primarily plant material that has decayed over time and broken down into its simplest form by microbes. If you think poop is organic, natural, and good for plants, then think of humic acid as microbe poop. Super small, super-rich, and super for your soil (but no foul smell). 

Humic acid is carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulfur, and the only reason it’s acid is that it’s a hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. And that is what makes humic acid so awesome!

It is known as a “chelator” (pronounced Kee-Lay-Tor), which in layman’s terms just means that it helps other nutrients become more available to the plants to be utilized. Think of it as a bridge between nutrients and your turf’s roots. To put it simply, applying humic acid to your lawn and watering it into your soil helps the turf roots extract more of the naturally existing nutrients from the soil AND makes the fertilizer you apply more efficient. If we were talking in automotive terms, it would be like adding a shot of nitrous to increase your speed.

The process of N-Ext Humic12 stands out against the competition. Their “long brew” technique using high-quality oxidized lignite, allows for a cleaner, more flowable product with enhanced biological activity.
The benefits of N-Ext Humic12 are:

  • Increased root growth
  • Increased chlorophyll content
  • Increased nutrient uptake
  • Improved soil structure
  • Improved plant quality

Works great, faux fur blanket is like new again!
Just used this on a faux fur pet blanket that I have had for 2 years and never brushed. It worked amazingly! Since it was so matted it took a bit to do the whole blanket (50” x 40”) but short strokes got it looking like new very easily. Some fibers came out in the brushing along with pet hairs, but the rug shedding was minimal.

O. M. G. It worked so great!
First, let me say, I'm not getting paid for this. This is personal experience. I was about to discard this rug. 1. It's old, like 13 years old. 2. It's been in storage for 4 years. 3. It's matted, as you can see in the pictures. 4. It's brown. Them I saw how much rugs are!😳So I had to come up with something. This was cheap to see if I could salvage it and not spend over $100 on a new rug. The dirt and lint that came out was gross. But as you can see, I was able to make it look new-ish again. I'm keeping the rug and this brush! I have other sheepskin rugs that are smaller and brand new, so this will come in handy.

Worx better than expected. Much improved the appearance and texture after washing & drying my 6 sheepskin pelts and three faux sheepskin pelts. There’s always a natural shedding after a cleaning, but this DEFINITELY decreases those incidents I recommend.

POLYESTER?!?!
Color: Ivory, Size: 2' x 3' (Pelt), Color: Ivory, Size: 2' x 3' (Pelt)
POLYESTER?!?! So i just bought several of these. Nice and big and fluffy, looked very clean, very nice. Cats instantly were scared/curious. The back of the skin, the wool, all looked nice, and then I noticed it had a tag on it... The tag says... 100% POLYESTER! What?!?!? This is supposed to be New Zealand Sheep Skin pelt! Shouldnt be any Polyester at all. So, just before I was about to return it, i did a small burn test. I cut off a small bunch of hair and burned it. The fire tried to light but it quickly extinguished itself. And the smell... yes... the smell told me it is REAL WOOL and the fact the fire went out right away also confirms this is not oil based. THIS IS REAL, This is NOT Polyester. I guess also a lot of ppl are returning because of the tag, so these are at a HUGE DISCOUNT!!! BUY THEM UP!!! They also came in vacuum packed bags, looked nice and kept very nice. These are excellent! See my photos, the tag, the burned bunch of hair... fire went out, i tried it three times, fire kept instantly going out... smells organic like animal hair when burned, not like oil/polyester. ENJOY!!! I PAID FOR THESE, I was not given anything here!

Love this product!
Color: Linen, Size: 2' x 3' (Pelt)
This sheepskin elevated a boring leather couch to a luxurious sitting space! I purchased 2, one for each loveseat, as sometimes the leather is a little cold. The sheepskin with a small lumbar pillow and voila! A cozy place everyone gravitates to! The sheepskin is soft and cozy and everyone comments they want one! ha probably will get this as a couple of gifts (for those guests that said they wanted one too)
