I've used many, many different natural products to help give my plants an extra boost at the beginning of the gardening season as well as throughout each stage in the plants life up to fall time. The 2017 Ohio Spring got off to a horrible start this year. In March we were teased with well above average temperatures and it seemed as if we were going to have a great start to the gardening season. I start all of my plants from seed in a grow tent in my basement in February, so in April when the temperatures were still warm and my 150+ plants could no longer fit inside, I moved everything to an outdoor pop up green house with shelves and a thick plastic covering. Unfortunately about a week later, the temperatures plummeted and I had way too many plants in large pots to try and bring inside. I was under the impression that my baby plants were being well enough protected inside of their zipped up greenhouse during the cold 40 degree nights, but I was completely wrong. The temperatures hovered in the low 50’s and 60’s for the majority of April. At this point, I had already put my way over grown pumpkins in the ground at the end of April and tried to shield them using row covers. I knew the tomatoes and peppers wouldn’t survive the chilly temperatures so I did what I could to protect them. By May 15th, the temperatures had recovered into the mid 70’s and I felt confident enough to plant the tomatoes and peppers in the ground. Not even 4 days went by and our weather went down the drain again with lots of rain, and chilly temperatures falling into the low 50’s. I was praying that my plants would survive, but it was clear by the end of May that they were stunted. My tomatoes were PURPLE and the peppers were a horrific Kelly green. I bought the Fox Farms Liquid Feed in hopes of giving them a boost and mixed in some Epsom salts for good measure. I’ve been using this product for about 4 weeks, applying it to the base of each plant once per week, and I cannot even begin to describe the complete turn-around my garden has done. It gave my plants the nutrients and boost they needed to get out of their “funk” and helped them grow strong healthy root systems. My tomato plants are loaded with blooms and baby tomatoes, the pepper plants are all producing fruit, and my pumpkins/squash/melons are all producing fruit and new growth! I am definitely a believer of this company! The photos attached to this review were taken 22 days apart! Review: This is one of the better plant foods I have bought for my indoor grown veggies and herbs - This is one of the best plant foods that I have tried for my indoor veggie garden. I grow a few herbs, but grow more of the Japanese veggies that are extremely high in nutrients and aren't found in local stores. Since using this plant food my veggies are growing faster and are healthy even grown under lights. Many of the greens grow so fast it is difficult for me to keep up with the harvests. The veggies that I grow now are excellent for salad green when young, and later I harvest them to blanch and freeze them for future meals. These leafy greens include Komatsuna, Senposai, Bok Choy, Swiss chard, Giant Red Mustard, and kale (curly, Portuguese, Red Russian, and Scarlet). I also grow tomatoes, basil, rosemary, thyme, and a few others. I very much like growing my veggies indoors as there are no bugs and all of the foods are much cleaner than growing them outside. I am also confident that these veggies are better than what can be found in a store since I know how they are grown. In addition, the vitamin content is much higher as they don't lose vitamins in shipping, storage, and time spent in the stores. This plant food may seem expensive, but you get a gallon and need to use only 2-3 teaspoons, or 10-12 cc's, per gallon of water for a normal feeding. Since the container is large it's difficult to measure teaspoons without spilling. What I do is use a 10 cc syringe filled to the top which is 12 cc's.. This equals about 2.43 teaspoons and less is wasted trying to spill into a teaspoon. As the container goes down, I will pour it into a plastic cup and use the syringe to measure. Even with the number of plants I have to water, this gallon of plant food will last 2-3 months. UPDATE 04/05/19: I have been using this plant food for about 2 months, and planted new flats of dwarf bok choy Giant Red Mustard, and Red Komatsuna less than a month ago. I can see the growth daily. Even though the plantings are crowd, all of the plants look healthy and full with beautiful color. I use this plant food with every watering to make sure the plants get enough nutrients for healthy growth. Considering the growth I am getting in my plants, this is a plant food I will continue buying. I have added a couple pictures of the plants I grow indoors from seed. UPDATE0 9/08/19: I have been using this plant food for my indoor garden,including a variety of vegetables and herbs, for about 9 months. I have been using 10 cc's/gallon for every feeding, and the first gallon has lasted for the 9 months. Since they are being grown indoors, I don't have room to space them as you would outdoors. So most are extremely crowded to the point the containers they are growing in eventually are thick with roots and the plants depend on plant food for the nutrients required for growth. I use 10 cc's/gallon for every watering, and this seems to keep them growing. Many of the flats I have planted have continued to grow and produce for almost a year before I have to replant them When the leaves are small, they are used for salads. As they get larger, they are harvested and sauteed for meals. I do believe this plant food has supplied the nutrients they need for the exceptional continued growth. I have added more photos of the Swiss chard, kale, Komatsuna, Senposai, and collard greens that I have growing now in addition to some of the herbs and tomatoes. UPDATE 11/12/21: I have been using this plant food for almost 4 years, and am still very happy with it. I have added a few more pictures of some of the plants I grow. I hope this review was helpful for you. ## Features - WATCH YOUR PLANTS FLOURISH: This plant food for vegetables is designed to support growth.

If plants are transpiring a lot of water back off on the amount of fertilizer you use. **Q: I am new to fertilizing. For how long or how much time do you apply the mixed solution to each individual plant? Thanks!** A: The instructions are on the bottle, it all depends what your growing medium is. If its dirt its about once a week or a little longer. Never use the recommended strength, always start with half strength then work your way up different plants have different needs. If the plant is too green or growing too fast "long skinny stems" then cut back and if its too bad flush your plant with a lot of water then start with a lower strength. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing product! *by S***L on June 27, 2017* I was a little skeptical as to whether or not this liquid feed concentrate would actually work on my vegetable garden.
