Review: Tree food approved. I was filled with a lot of fear because i work with plant soil and data and they d honestly dont share a ton of data to the public but i went for it and changed all nutrients besides a few base chemicals and for the most part they are killing it and not growing funny either and thats why people dont bonsai with chemical's and nutrients like this but I have been doing a lot of work and research with less of the fast flowering "short life" plants and have been giving more focus on long lasting slow growing plants and trees (bonsai) and what effects soil life and proper nutrient management has on them to find ways to save the soil strength and microbiome making stronger, healthier and higher yeilds. It is very difficult as a bonsai and plant guy is i know that they want to grow faster and bigger but typically its to much and the tree will look not as good and willl look good/big in the wrong way so to find a product not directed to only weed or flowers and can my plants can sustained all year use with proper measurements and nutrient management (depending on the plant) this is really one of the best set of mixes out there and i could show you some data of some of my plant growth within just the first 2 weeks of growth after i started my new nutrient cycle i couldnt belive some of my plants it seamed unbelievable but now they have slowed the growth (from bad growth to even growth they just needed time to get a little crazy. Things are much more prepositional now that i gave them some time. I like to give additional pure nutrients and not just premixs you mix haha but thats way to much for anyone to dedicate there time to unless they really love plants and thats why i love this kit for making gallons and all my soil based plants get some food once a week changing only by age or time of year and for most of my plants they all get this and its a simple way to get to know nutrients a little more plus this is high quality stuff, my plants love it and the early season data looked really good besides one juniper i think may have ODed and has been brown all season so be carful less is more at first, but its really simple and worth the price for short and long life plants also. I even use a diluted mix for my house plants not in the data but it works so good for more gallons of water worth of mix it takes lightwork of the process and i dont need a scales and it really is a pretty good multipurpose feed to take the average grower a step up a level. I would say Professional quality i would stick to making or buying what you have. This helps me manage the large number of plants that i need to feed during the summer with a little less effort so this works for me perfectly. Id like to see some microbes, soil building products or even pure nutrients or atleast try and or do a study....I can show you data....The future is here dont be late. I would make the full switch to Humboldt secrets but the lack of meaningful products is not enough for me to do that yet and thats alright because i think they are good and one of the best for price/quality products out there but not the best and lack of product really holds them back. but if plants are not youre life or way of life this is by far one of the best options. Even just Base A and B would do great if youre looking for just a taste

## Questions & Answers

**Q: Why is it not for sale in california ? 😭**
A: Because California claims everything causes cancer

**Q: Is it organic?**
A: No

**Q: Is this a petro chemical salt based solution**
A: No

**Q: Do you think that they’re adding the wrong amount of nutrients that’s why it’s killing some plants?**
A: depends on what medium you are using. Most people don't use washed coco. or use pre-amended soil and have no idea how much nutrients are already in it. or aren't watering enough or don't have ideal humidity so the plant drinks more and gets burned. if there isn't enough water it will become more concentrated. there are 100 reasons why growers make mistakes. Almost every single nutrient line could be amazing if used properly and at the right doses for what the plant genetics ask for. Most of the time it's grower's error. Better to go lighter on nutrients then too heavy. Plants will hurt less and bounce back faster with a deletion rather than abundance of nutrients.
