    This blend is nothing short of amazing and is the best all around fertilizer I have found to date. I replaced all of my complicated two and three part solutions with this easy to mix blend and my plants have never looked better. If you’re growing peppers or tomatoes, mix this with Kelp4Less gypsum and watch your plants flourish!

    I have used this on lettuces, tomatoes, radish, strawberries and various flowers and they have all responded nicely to both soil and foliar application. The powder dissolves quite easily in water. A very good product.

    I’ve done all my liquid fertilizer shopping needs right here at kelp4less.com the last two years. I’ve tried numerous products but this is the one that gives great immediate and noticeable results. This product has given me so much faith in their blends that next year I’m giving their grow pack a shot. This place used to save me money, now it saves me money and time.

    I have been using this product for about a year and have yet to be disappointed by it. I have used it on all my plants, and have given a ton away to other people, and have gotten back nothing but requests for more, and stories of surprising growth and green-ness.
    It compares very well to similar products from other companies, except in value, where this trumps others by far, instead of tablespoons of liquid per gallon out of a $40 dollar quart, its the tiniest amount of powder per gallon, or a tablespoon in a sprayer can feed your entire garden.
    Highly recommended for all types of common plants.

    I absolutely love this product. Gave my plants the added pick me up they needed each week. Plants responded within hours and results were visible same day. I am a believer and will continue to use Extreme Blend.

    Extreme Blend is my new beauty secret. After three applications, the foliage is taking on that dark blue green foliage color that I had coveted, in the garden of others, for so many years,

    I stumbled onto Kelp4Less after reading blogs touting their wondrous products.
    I was sold when I listened to the video describing the Extreme Blend. It sounded like something which suited my sensibilities. I really appreciate the mixing concentrate which I apply with a hose end sprayer. I use one gallon of concentrate per application, divided into eight fillings of my sprayer container. I use this spray on mostly roses, daylilies, and clematis. I have too many plants to count and this economical product makes my garden look so nice. The foliar sprays that I have used in the past were ready-mixed and expensive if used in the amounts that I require.

    I have long been in search for a easy, powerful foliar feed which would give me quick results. I have found what I was looking for with Extreme Blend…….

    I use extreme blend on my giant pumpkin plants and It keeps the leaves and soil healthy. Even in the heat and non stop rain in North Georgia my plants look good all year.

    Extreme Blend is by far hands down the best foliage spray for leaf applications. I have been using this product for several years and the results are amazing. Here in Colorado the growing season is less than 4 months. I have been using this on all my deciduous trees and shrubs. The best time to apply is in the evening after a rain or any day when it is 100 percent cloud cover and high humidity. My cottonwood trees have averaged 2 1/2 to 3 ft. growth per growing season. All plants treated with the extreme blend have expressed similar results. I have not had good results on conifers through foliar spray, but through root ball applications. This product is also excellent for your house plants. For best results mix as recommended as more concentration could burn your plants. Kelp 4 Less is now my only source for horticulture products. Do your research and you will find they have the best products for the money and the free shipping seals the deal. You must try Extreme Blend and use it as directed for one growing season and you to shall be amazed. Best foliar spray on the market, period.

    This is the greatest stuff I have in my collection of nutrients. The plants come alive when they get it and the color of the leaves is a dark forest green, beautiful! The taste from my fruit is the best, with a sweat nutty flavor that was not noticeable before using this product. Highly recommended.

    We have had difficulties with the purchased soil in our garden for the past two growing seasons and I believe that the extreme blend is the only thing that has kept any of the plants alive and producing. I split the package with a family member who gardens in sandy soil in northern Ontario, Canada. They had never had such a beautiful and productive garden as when they used your extreme blend and liquid gold. We are truly glad that we found Kelp 4 Less. Thanks you.

    I used the extreme blend this season on my beans and tomatoes. I got 20+ bushels beans more than ever before and still harvesting tomatoes.

    Last year was the first time I used this product. I used it as a foliar spray. I was kind of hit and miss with it.I did notice however that the plants loved it. Talk about come to attention. So this year I’ve been using it weekly. WOW is all I can say..The results are well worth the effort.

    The bulk of my gardening is spent on growing giant pumpkins, and Extreme Blend combines several of the key products needed to “grow ’em big”. Extreme Blend will be a part of my arsenal next year again.

    I was going to wait 6 months before leaving a review, but after close to 4 months of using Extreme Blend, I couldn’t wait any longer. I hybridize and sell daylilies in Southern CA. Most of my daylilies are evergreen, so I’m tending to them all year round. Some are in the ground, in raised beds, and in various sized fabric pots, etc … After using Extreme Blend, I have watched each and every daylily, regardless of where they are planted, in my little nursery literally transform! The new foliage on the established plants increased at least by one-third in width! I even sprayed EB on some seedling, and the same thing happened. The new growth is noticeably larger, more vibrant, and stronger. Just amazing … I use it with a pinch or two of yucca powder and spray once a week. Oh, and I spray it on all my other plants and trees as well with noticeable results, but my daylilies have responded the most. EB is truly an economical and effective product, and it’ll make your neighbors think that you actually know how to grow plants 🙂

    Have been using this Extreme Blend over Bud Candy for the last four weeks and can honestly say “GoodBye” to Bud Candy! Depending on the Extreme Blend strength is determined by what stage of growth my garden is in because it has become my base nutrient in either stage veg or bloom, I won’t grow without it!

    Great customer service. Fast shipping. Excited to see if this product work. I am going to intentionally attempt to nutrient burn some of my high value flowering plants to verify concentration of product. Will update with results.

    This product is simply amazing….lush, green, thriving plants after first application and weekly applications result in large, healthy plants.

    Amazing stuff plants really do respond within 48 hours and as long as the plant likes nutrients it will love this. Used on milkweed and it deformed it because milkweed doesn’t like much nutrients. Whoops haha. But my tomatoes were over 14 feet tall and same with my other green stuff. Have recommended to many people who have also had much success.

    I use Extreme Blend at 1/4 tsp with a 1/4 tsp yucca per foliar gallon and have seen amazing growth on kale, mustard greens, spinach chard, carrots, tomatoes, strawberries, lettuce, fruit trees, and roses. Leaves turn a dark, healthy green, trichrome hairs were explosive on tomatoes, and my spinach chard grew leaves at least 5 times larger than I’ve ever seen. I spray everything once a week and everything seems like it’s growing in turbo.

    I have used this product for 2 or 3 years now. That is to say that I have purchases it enough to last the year. Good product . Does a very good job with tomatoes and peppers. Great for blueberry plants also. The foliar application is very good also for added plant development. Truly noticeable.

    I have to say for a certainty this product works! I saw all the reviews so decided to add it to my lineup for organic gardening. I use a very porous, light-mixture of about 60/40 peat/perlite. I grow in air pots and bags, etc. I use this product very lightly Itbsp/5gal rainwater with every watering, which ends up around 3 x week. Ive had great results though I use several different products its hard to say for sure it was tis product specifically. Then I had an idea to add a little to some water when was planting tomato seeds. I start my seedlings in trays under LED High Output lights. I started 4 trays of tomato seeds on the same day using the same coco coir/perlite 80/20 ratio for all. I have always been told not to add anything to the water when you first plant seeds. Well, I decided to use one tray as an experiment. Long story short, that tray using the Extreme Blend @.5 tbsp in 5 gallon bucket of rainwater outperformed all the other trays even ones that were planted a week before. The experimental are working on their 3rd set of leaves/2nd true leaves and the other are still popping seed coats off. I will be using this in everything from now on! I have pictures but can’t load them here.
