OMRI Listed

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.

            Great pillow
            Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
            Very well made pillow! It doesn't go flat right away like so many other pillows do. Very comfortable as well. I would purchase again.

            Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
            I bought these pillows with the pillow protectors included. After 15 minutes of fluffing the pillows in the dryer they took their shape and were ready to use.

            Nice medium thickness. Fits in shames great. Firm for a medium but will work well
            Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
            Nice pillows for the price. I got the medium thickness and it’s a little stiff, but I think once slept on, it should soften up a bit, but if you like a softer or flatter pillow, definitely go for the soft one. But the quality seems to be very well-made. It puffed up straight out of the package. It didn’t have any smell whatsoever, and it fit perfectly in my standard size shams.

            Loved them but may not last too long
            Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
            I’m kind of torn on these. I love them and I want to buy more because they were very affordable and very comfy! I’ve had them less than six months and they lose their plumpness after a few nights sleep but they are easy to fluff back up. They are pretty thick and firm but form to your head and neck perfectly..for me at least. I’ve tossed them in the washer and dryer and they have been fine. Fluffed right back up perfectly. The material inside seems to be clumping together now. it’s easy to fluff them back out but you can notice the spaces where they’re starting to clump and even though they can be fluffed again it does seem they are starting to become compacted and I find myself having to fluff them more often. I’ll see how much longer they’ll last, but I will buy again because they are pretty comfortable. I love the covers they came with also. They stay cool and wash easy! Overall, great for the price, maybe not in the long run if you continue to buy, but I’ll see how much longer they’ll stay in good shape!

            Best pillow!
            Size: Standard (2 Pillows + 2 Protectors), Style: Medium, Configuration: Pillows + Protectors
            These are the most comfortable pillows ever. I would recommend going with the medium fill.
