Finalsan® is a patented fast-acting weed, grass, algae, and moss killers that represent a new class of products for organic weed control that do not contain glyphosate or other toxic chemicals!  Utilizing concentrated and potent and non-staining fatty acids (soaps), Finalsan is a non-selective herbicides and the best new top-of-the-line technology for fast-acting and through killing or suppression of many common annual, biennial, and perennial weeds, algae and mosses. A great organic product for use when conventional herbicides are banned or not desired!

We are now excited to offer Finalsan in smaller, more home friendly sizes under the Captain Jack's Deadweed Brew label! Now you can treat your own lawn with professional-grade results!

Why is Finalsan the Best Natural Weed Killer?

Herbicidal soaps work by penetrating the waxy cuticle of plants, causing the plant to dehydrate and die. The active ingredients accumulate in plants and cause intracellular damage, leading to cell death. Activity is non-selective and will kill plants the soap comes into contact with, but will not translocate to underground portions of the plant or harm the bark of mature, woody plants.  Can be safely sprayed around the base of trees, shrubs, hops, grapes without worry.  

Use on weeds within vegetable and flower gardens, landscaped areas, lawns (for spot treatment only), in the vicinity of small fruits and fruit trees, around and on buildings, sidewalks, fences, bark mulch, driveways, patios and gravel.  Use on moss and algae, around and on buildings, roofs, decks, sidewalks, fences, bark mulch, driveways, patios and gravel. Finalsan can even be used in cool weather. Areas can be planted five days after treatment.

Finalsan reduces tree toxicity risks and leaves no harmful residue in the soil. It won’t stain bricks, concrete or asphalt and people and pets can re-enter areas once spray dries.

            Excellent adjustable drafting chair
            Size: 934-Z, Color: Blue
            Excellent chair design, extremely comfortable and exceptionally easy instructions to follow making for simple assembly. Love the amply wide cushioned seat and ergonomic backrest. The height adjustment feature works perfectly as well as positioning of the foot ring . Having the ability to raise the arms is also a big plus! I highly recommend this product for attractive appearance, comfort features, functionality and operation. Really nice chair!

            Comfortable, stylish, and perfect for long work hours 💗✨
            Size: 934-Z, Color: Pink
            I bought this chair because I spend a lot of time working and needed something comfortable but also stylish, and I absolutely love it. Since I started using it, I feel much better support in my back thanks to the lumbar support. It makes a big difference, especially during long work hours. The adjustable footrest is also a feature I didn’t know I needed, but now I use it all the time. The flip-up armrests are very convenient because I can adjust them depending on what I’m doing or move them out of the way when needed. The pink color is beautiful and adds a soft, elegant touch to my workspace. It looks great in a modern home office. It feels sturdy, well-made, and very stable. Overall, it’s a great purchase that improved both my comfort and the look of my workspace.

            All-around thumbs up!
            Size: 934W-Z, Color: Black
            So far, so awesome. Easy to assemble, comfortable, arrived quickly and is exactly what I was looking for. I have a tall work bench in my new studio so I needed a chair that we could allow me to sit higher than a regular office chair and allow me to get off my feet after standing on the concrete floor. Plus its a nice looking chair that I am sure will last a long time. I love the flip-up arms and the lumbar support. This is just right!

            Perfect Balance of Comfort, Support, and Style!
            Size: 934-Z, Color: Black, Size: 934-Z, Color: Black
            I’ve been using this chair for a few weeks now, and I’m genuinely impressed with how much of a difference it’s made in my workspace. The mesh back is one of my favorite features—it offers excellent breathability and prevents that sticky, overheated feeling you sometimes get with solid-back chairs, even after sitting for hours. The seat cushion is firm enough to give proper support but still has enough give to keep me comfortable through long workdays. It feels like the perfect middle ground between soft and supportive. The adjustable foot ring has been a complete game changer for me. I use a taller desk setup, and having somewhere to rest my feet makes a huge difference in posture and overall comfort. Whether I’m sitting upright for focused work or leaning back to read, it’s always at the right height. The flip-up armrests are another smart design choice. When I’m typing, I like to have them down for support, but when I’m done, I can flip them up and push the chair neatly under my desk—saving space and keeping things tidy. The casters roll smoothly on both hardwood and rugs, so I can move around easily without scraping the floor or getting stuck. The overall build quality feels solid and sturdy, with no wobbles or creaks. Assembly was surprisingly quick—everything was clearly labeled, the parts felt durable, and it only took me about 20 minutes from opening the box to sitting in the chair. The sleek, modern look is another big plus—it blends in perfectly with my home office décor without feeling bulky or taking up too much visual space. If you’re looking for a chair that combines comfort, ergonomic support, durability, and style, I can’t recommend this one enough. It’s equally great for work, studying, or just relaxing at your desk, and it’s definitely been worth every penny.

            OK for the price, but overall comfort is avergae
            Size: 934-Z, Color: Mustard
            Easy to put together, color (mustard) accurate to images, and while I understand this is not a high-end chair, I feel like it still needs to be rated for its quality. Pros: the seat cushions are fairly comfortable and it rolls well. Adjustable footrest is easy enough and mostly sturdy. Cons: For a tall office chair, it doesn't go up high enough. I actually had to lower my standing desk to sit at it, which then isn't where I want it when I'm standing now. It's also a bit wobbly. The seat area's attachment to the post isn't as solid as it should be for a tall chair, so while sitting, it does tend to lean/slope forward and wobble side to side. The lumbar support is not adjustable, so I'm not even really sure what it does. And the armrests are not very comfortable to use. Since they are hard plastic, they are just a bit too rigid to rely on for any comfort. They are basically there to hold on to when you're getting out of the chair.
