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

Help training kitten poop
I have young kitten. It is attractive to me to use the Potty Training Tray. Kitten does not know to go to litter box initially. And they even eat cat litter. For safety, the trining tray is a good start to train their poop habit and also help a smooth transition to litter box when they get older.

Training pad holder literally rises above the competition
Size: 24"X24"
We have been through a variety of potty pad products during our housetraining journey with our Havanese pup. The Petphabet training pad holder has been the best by far and has ended our search for a number of reasons: Pros: 1. Grid design keeps puppy from chewing/tearing/destroying/eating the potty pad. 2. Size is perfect for our pup even as he is getting bigger (15 lbs) - mileage may vary for larger pups/dogs. 3. HERE IS THE REASON THIS PAD HOLDER STANDS OUT AMONG THE COMPETITION - The top grid is elevated off the surface layer where the pad lays, which allows an air gap between the standing surface and the potty pad. This allows the urine to fall to the pad without pooling and without your pup stepping in it and tracking it everywhere! Cons/Areas for improvement: 1. We like blue but it's not for everyone! 2. The "posts" holding the mesh up from the base carry all of the weight of the dog and in some cases jumping or playing on the pad holder can cause the edges of the posts to cut through the potty pad liner, causing a (minor) leak. I would recommend the manufacturer design any subsequent models with larger, flat surfaces on the post supports. 3. The 4 piece design means the base is not solid but has a split down the middle that is not waterproof. This can be remedied by caulking the 2 sides of the base together with clear silicone assuming you will no longer need to disassemble the unit. 4. Poo can get caught in the grid if your pup has loose stool. If not removed quickly your pup may step on it and really pack it in there. After many trials with other products, we are very happy with this training pad holder and have bought a total of 3 units for different areas of our house. I highly recommend for small dogs/pups!

Works Great!!!
Size: 18"X24"
I have 2 pugs and have trained them to "go" on a grid. I started with another brand (Klean Paws) but found this brand (Petphabet Puppy Training Pad Holder) to be superior in several ways. This training pad holder is designed much better. The plastic grid is well supported so the puppy does not get wet paws when waling on the grid. The overall design of the training pad holder makes it very easy to replace training pads. Standard training pads (17.5" x 23.5") fit the medium Petaphet puppy training pad holder perfectly. Just lay the pads flat on the bottom, place the grid on top and clip it all into place with the frame. The frame holds everything in place and keeps any loose ends, hidden from mischievous puppies. It takes a lot of effort to train puppies to "go" on a grid, but it's worth it. I started with one grid in a crate. Then, I gaited off my kitchen area, with 4 medium grids (as shown in the video). You cannot expect a puppy or dog to just go to one spot and do their thing. Dogs like to sniff and walk around before they "go." They need room. I suggest 2 medium girds per medium-sized dog. I have 2 pugs and 4 grids. I reward them with a pinch of peanut butter, whenever I see them go on the grid. I simply pickup the #2 with TP and flush it down the toilet. I replace the pads, in the 4 grids, once a day. NOTE: The sellers of the dog training pad holders seem to come and go. If you cannot find this particular training pad holder, do a search for Mesh training pad holder. Be sure to get a training pad holder that has 3 parts -- the bottom tray, the mesh grid, and a frame that holds it all together. Some of the simpler grids have just 2 parts (bottom tray and top). They are simpler, but do NOT keep paws dry.
