Why use it unless you know you need the micronutrient help? ...especially at it's expensive price point.

I find it to be an overpriced seemingly kelp-heavy (given what it promises to deliver that they bother to share) mixture. It also has a long history of deceptive and to-the-moon promises. They used to sell it with wild promises on QVC and their own company literature is extremely sketchy.

Unless you have more money to burn than time, and you actually need it...I guess it's fine, but the hype on it is extremely unwarranted and they present extreme findings on it's use as "normal."

You can bet that if it did even a 1/4 of the performance they claim in their literature that large/medium agriculture farmers would gladly pay the $100-$120 a gallon of the magic elixir they claim they produce.

What does a good reliable soil test tell you about the nutrients in the soil?
What nutrients do you think you are missing and need to supplement?
Keep in mind that you can create more problems with excess nutrients. Spraying something more than likely is simply a waste of your time, energy, and money.

I have only tested P, K, cal, mag and OM and ph. The micronutrients are not included in the U of M tests. So I know my cal and mag is high but cannot know about the micronutrients. I know I do not need the fertilizer but I was wondering just about the Spray n Grow due to my neighbor farmer's results.

If you type Spray n Grow in the search bar you can find many discussions and reviews about it.

What is your neighbors soil like in comparison to yours?
Amount of organic matter?
Soil pH?
Levels of P, K, Ca., Mg. etc. ?
Does that neighbor follow the same growing practices you do with the exception of the Spray and Grow?
Does that neighbor use synthetic "fertilizers"?
Are the neighbors plants adversely affected by insect pests and plant diseases more than yours?
