    Liquid kelp, also known as seaweed extract, is a natural fertilizer made from seaweed. It contains a variety of beneficial nutrients, growth hormones, and trace elements that can promote plant growth and health. Many different types of plants can benefit from the application of liquid kelp, including:

     

    Vegetables: Various vegetables such as tomatoes, peppers, cucumbers, zucchini, broccoli, and leafy greens can benefit from liquid kelp's nutrients, which can lead to improved yields and overall plant health.

     

    Fruits: Fruit-bearing plants like strawberries, blueberries, grapes, citrus trees, and apple trees can benefit from liquid kelp, which may enhance flower and fruit production.

     

    Herbs: Culinary and medicinal herbs like basil, mint, cilantro, and oregano can thrive with the help of liquid kelp, as it supports their nutrient uptake and essential oil production.

     

    Ornamental Plants: Flowers and ornamental plants, including roses, orchids, lilies, and many others, can experience improved root development and enhanced flowering when treated with liquid kelp.

     

    Lawns: Applying liquid kelp to lawns can improve soil health, stimulate root growth, and increase the lawn's ability to withstand stressors like drought and disease.

     

    Shrubs and Trees: Landscape shrubs and trees, such as azaleas, rhododendrons, and various ornamental trees, can benefit from the use of liquid kelp to support their growth and overall vitality.

     

    Indoor Plants: Houseplants, such as spider plants, pothos, peace lilies, and many others, can also benefit from the application of liquid kelp, providing them with essential nutrients for healthy growth.

     

    Liquid kelp can be applied as a foliar spray or as a soil drench, and it is generally considered safe and beneficial for most plants. However, as with any fertilizer or plant supplement, it's important to follow the recommended application rates and guidelines to avoid over-fertilization, which could be detrimental to plants. Always read the product label and follow the manufacturer's instructions for the best results.

Works great
Size: 6ft, Color: Silver
Just what I needed for my Dept 56 Christmas display. In past years, it's been a challenge to find enough open plugs for my display. This power strip completely solved that problem. I wish I had found this sooner.

Better than expected - big office cleanup
Size: 6ft, Color: Yellow, Size: 6ft, Color: Yellow
I got this power strip because it seemed like the most plausible one available, notwithstanding the reviews which particularly complained about it being prone to overheating. I certainly didn't want to burn down my home, so I tested it pretty thoroughly before I got anywhere near installing it. The power strip arrived exactly as claimed. It is indeed 45 inches long with sixteen outlets. The power cord is substantial-feeling, and feels like it's probably 14 AWG, or possibly #12 (Pic 1), and was the length I expected (6' in my case). The mounting brackets are sufficient to mount the power strip, but only at the ends, and they can't be concealed. This means that things don't end up as solid as one would like, and if you really care about aesthetics you'll end up being offended, but hey this is a power strip, and if you didn't have it the power cord mess would be way uglier. The outlets themselves are spaced out well enough that there's enough room to put in fairly wide wall wart transformers, but not those which have the plug pins configured such that the transformer has to point sideways. This means that if you want to be able to fill all of the slots, you can only put one of these in, and it has to go at the right-hand end. If you locate it on the left then it covers the switch. In my case, I filled the strip up completely, with one sideways transformer at the right hand end, and I still have many more plugs which won't go, but I've at least managed to improve my cable management a fair bit. Before I installed it, I tested it by boiling an electric kettle using the outlet which is the farthest from the switch (Pic 2). This is the most stressful way to test things, since is stresses all of the wiring and intermediate outlets before it even gets to the one I was using. The kettle draws 11.6 Amps, so about 1400W (though it's amps that actually matter). I then watched the thermal behaviour of the power strip as it worked. As can be seen the first thermograph, Pic 3, the power strip itself stayed cool, indeed barely above ambient. The power meter and power cord going to the kettle are on the right. Pic 4 shows a detail of the switch end of the power strip. The switch never heated to above 77F, which was again barely above ambient. Pic 5 shows a detail of the power meter shown in Pic 2. As can be easily seen, the power cord for the kettle warms up a bit, reaching 100F, but this is clearly the kettle's power cord and plug warming up, not the power strip itself. Pic 6 shows a detail of the unused outlets on the strip. These all warmed up a little, but never got over 83F. To me, this is negligible. As a result of this testing, I had no problems with going ahead and installing the power strip. I knew I'd be filling the power strip, but just adding up the devices I planned to plug in (two desktops, four screens, and numerous other devices), I knew that I wouldn't need more than about 4.5 amps, so I have at least 2.6X headroom. Pic 7 shows a part of the power strip as installed - I couldn't get far enough back to show all of it. Pic 8 is a thermograph of the same, with the power strip running across the middle of the picture. The how spots on the power strip are all transformers - clearly not very efficient, but not actually more than warm, and not the power strip's fault. By contrast, the really hot items visible are a DSL router on the far right, and a VOIP phone device lower on the right. Thus, I conclude that there's nothing untoward with the power strip. Lots of the devices I use are inefficient and/or run fairly hot, but if my house burns down, it doesn't look like it's going to be because of this power strip. All told, this product seems to be very good value for something that actually cleans up my life and has this many outlets. It exceeded my expectations, particularly since my expectations had been lowered by some of the other reviews. It would certainly have been better (for me) had it been longer and with more, and more widely-spaced, outlets, but I can't fault them for making what they made, and their claims seem to have been accurate. Still, the construction is not terribly sturdy and the mounting brackets should have been better thought out.

Plenty of Outlets and Solid Build
Size: 6ft, Color: Silver
I now have way more outlets than I’ll ever need—haha—but that’s not a bad problem to have! This power strip fits neatly behind my TV stand and feels very well made. The spacing between outlets is convenient for larger plugs, and it seems built to last. Overall, a high-quality and practical solution for managing multiple devices.

Good for dc power supplies
Size: 6ft, Color: Yellow, Size: 6ft, Color: Yellow
The AC outlets are very snug. I’m using this primarily for battery tenders and battery chargers; the outlets are spaced far enough apart to fit the dc power supplies and they stay in place even when mounted horizontally.
