    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.

A much more affordable option for Subaru owners
Size: 5 Quart, Style: 1 Pack
When you're paying between $16 & $18+ per quart of Subaru brand CVTF 2 fluid this is a much more affordable option. If you look on the back of a Subaru branded CVTF 2 quart bottle you'll see the Idemitsu logo. Doing this job myself saved me over $1000 on what the dealership quoted me to change the valve body and drain and fill my CVT without skimping on anything.

Same fluid as the Subaru brand
Size: 5 Quart, Style: 1 Pack
This is the manufacturer that makes the Subaru cvt fluid. I used this for the drain and fill on a 2019 Subaru Forester. No problem using a hand pump to fill the transmission. Excellent product will use again to service a 2018 Subaru Crosstrek.

2010 Subaru Outback CVT fluid 👍
Size: 5 Quart, Style: 1 Pack
2010 Subaru Outback CVT ... have been using this for several thousand miles instead of OEM fluid, and works just fine ... if your subie takes the "green" CVT fluid, this works excellent! I even used this after dropping the CVT valve body and replacing the lock up solenoid, so I had to replace with almost exactly 10 qts of fluid.

It Works! (Mustang 2016 ecoboost knocking noise)
Style: Modifier
I recently experienced a remarkable transformation in my 2016 Mustang Ecoboost, thanks to the LIQUI MOLY Oil Additive Cera Tec 3721. As someone with a passion for automobiles and a background as a software engineer, I'm always on the lookout for ways to improve my vehicle's performance. This product turned out to be a game-changer. One of the issues I had been facing with my Mustang was a persistent knocking noise, which can be quite concerning for any car enthusiast. After researching potential solutions, I decided to give LIQUI MOLY Cera Tec 3721 a try. And I must say, I was pleasantly surprised by the results. The primary reason I opted for this oil additive was its promise of ceramic wear and tear protection. As someone who values the longevity of my vehicles, I wanted to reduce engine friction and wear as much as possible. This product did exactly that. The moment I started using it, I noticed a significant reduction in engine noise, especially the knocking sound that had been bothering me. It provided a smoother engine performance, and the difference was noticeable. What impressed me even more was the impact on fuel consumption. As someone who loves to travel and has explored six states during my time in the USA, fuel efficiency is a key concern. LIQUI MOLY Cera Tec 3721 not only improved my engine's performance but also led to lower fuel consumption. This means fewer stops at the gas station and more miles of adventure. Moreover, being a mentor and research assistant, I appreciate the science behind this product. It's clear that LIQUI MOLY has put considerable effort into developing a high-quality additive that benefits both petrol and diesel engines. This is the kind of innovation that I believe will shape the future of the automotive industry. In conclusion, LIQUI MOLY Oil Additive Cera Tec 3721 has not only fixed the knocking noise in my Mustang but has also enhanced its overall performance. It's a product that aligns with my goal of staying at the forefront of technology and innovation in the IT sector, even when it comes to my car. I highly recommend it to anyone looking to improve engine performance, reduce friction, and achieve better fuel efficiency. It's a small investment with significant returns for your vehicle.
