How have I only JUST reviewed this? This is basically my secret weapon. I’m half convinced it’s magic in a bottle because everything I use it on suddenly decides to thrive. Plants that were barely hanging on? Revived. New plants? Thriving like they pay rent. It works on everything—indoor plants, outdoor plants, the “I forgot about this in the corner” plants. Foolproof is not an exaggeration. I don’t even try that hard anymore, and somehow I look like I know what I’m doing. I don’t fully understand what’s in it, but whatever the formula is, it’s clearly high quality and actually does what it promises. It mixes easily, no weird smell, no complicated steps—just simple and effective. If you want lush, green, “wow what are you using?” kind of plants without becoming a full-time gardener, this is it. Secretly I think that this is the reason why I didn't review this before - heh.

I’ve been using this about once a week on my plants and they have responded really well! Lots of new growth on them and I’m excited for them to bud up!

It might be too early to tell conclusively, but this fertilizer may have reversed a phosphorus deficiency in my tomato seedlings. They started off well a couple of weeks ago and then started turning dark purple and growth came to a standstill. So, I hit my plants with a low dose of this fertilizer (2 Tsp per gallon). In two days 2 if the three seedlings are back to green (leaves and stems) and one is still purple but less so. In addition all of them are putting out new growth. So, it looks like Grow Big rescued these plants! I'll update this review to confirm/correct this review over the life of these plants. So far, I'm impressed.

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.
