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

  • 1 Single Quart (32 oz) = covers up to 5,325 sq ft

Sorry, Brother. Epson smashed you.
I have been a long time Epson user. I have owned their printers, all-in-ones, movie projectors, and even a receipt scanner. In all cases, I have always found them to be the best performance per dollar of any of the big guys. There kind of like Panasonic in cameras where people may talk about some other big names, but what you get per dollar is always good from them. Somewhere along the way, I got disillusioned with companies charging me $60 per pack of ink. I'd get really mad when I couldn't print black text because red or something was out. For a few years, I gave up and just went black and white laser printer. The toner was dirt cheap, and my printing cost dropped to virtually nothing. But, my ability to pront pictures was gone. No more color at all. I'd have to go to a print business if I needed color copies. Well, this finally changed that. The EcoTank is a great design. The "Eco" stands for the economic cheap ink it takes, and the "Tank" refers to the big holding tanks for the ink and give long ink life. Epson probably makes the best ink, but many manufacturers sell inks for this printer. There's none of the stupid compatability issues with cartridges. It's 2026, so of course it all connects wirelessly over WiFi. It's wonderful. The only issue is that you might have to do a little more maintenance to keep it reliable. If you let old ink carts sit too long, you could just replace them. Here that isn't an option. I've seen Youtube recommendations that say you should probably print a color page every week or two, so factor that in to keep it running well. I love it. Five stars.

Solid Printer for Regular Use
I ordered this Epson EcoTank ET-2903 because I wanted a printer that did not make me feel held hostage by tiny ink cartridges. The refillable tank system is the main reason this printer stands out. Being able to see the ink levels on the front and refill from bottles makes the whole process feel less wasteful and less stressful. Setup was straightforward. Filling the ink tanks was easier than I expected because the bottles are keyed to the right color, so you are not guessing where each one goes. I did not have a mess during setup, and that was my biggest concern with a tank printer. Print quality is strong for normal home and office use. Black text comes out clean and easy to read, and color prints are bright enough for school projects, labels, recipes, forms, and casual photo printing. It is not the fastest printer I have ever used, but the tradeoff is lower ink stress and better long-term value. The wireless printing is convenient once it is connected. I like being able to print from my phone or laptop without moving files around. The scanner and copier are also useful for everyday paperwork, receipts, and documents. A couple practical notes: this is a rear-feed paper tray style printer, so plan where you are putting it because it needs some clearance. Also, it does not automatically print double-sided, so duplex printing takes a manual flip. For value, the ink tank system is what makes this worth it. If you print regularly and are tired of buying cartridges, this is a smart home office upgrade.

Epson EcoTank ET-2903
Epson ecotank are great replacements for standard printers. The fact that you get to use the ink bottles rather than the rip off ink cartridges that only last a little while is an amazing benefit. They print well and have a good print quality, so much so that we have one for normal printing and one for sublimation printing. I do all my printing wireless and have the rate occurrence that it has connectivity issues, like all printers. It holds a good amount of paper making refills less often Than the cheaper printers. To me it has been perfect for my small home business.

Goodbye Ink Cartridges
I’ve used cartridge printers for years, and the EcoTank system is honestly the biggest selling point here. Filling the tanks was much easier than I expected thanks to the keyed bottles, and I didn’t make a mess during setup. Print quality is sharp for everyday documents, and color prints come out vibrant enough for school projects, photos, and crafts. The scanner works well, the wireless setup was straightforward, and being able to print directly from a phone is convenient. I also appreciate not having to constantly wonder if I’m about to run out of ink after a few dozen pages. The printer itself is fairly compact for an all-in-one unit and fits nicely on a desk. While it isn’t the fastest printer on the market, the long-term savings on ink and the hassle-free refill system make it a solid choice for a home office, students, or a family that prints regularly.

My Go-To Sublimation Paper — Flawless Results Every Time
Size: 8.5"x11", Size: 8.5"x11"
This is hands down the best sublimation paper I’ve used and the only one I continue to buy. I get a perfect transfer every single time—no fracturing, no fading, and no uneven results. The paper dries fast, which makes my workflow so much smoother, especially when I’m producing items in batches. I use this regularly to make air fresheners and tote bags for my small business, and the color payoff is always vibrant and crisp. The transfer rate is excellent, and it works beautifully on light-colored, high-quality polyester and other sublimation-ready surfaces. If you’re a small business owner or crafter who values consistency, quality, and ease of use, this paper is absolutely worth it. I highly recommend it and will continue to repurchase.
