Grows gorgeous vegetables
We ran out and our plants definitely went downhill. We use this as the base and add other nutrients as appropriate. An excellent base for higher fruit/vegetable production and quality as you're transitioning to a fully sustainable system.

Works great in my Hydroponic and Wicking Tub/Tote systems. In both applications, the Masterblend 4-18-38 is one part of the Water/Fertilizer Solutions I blend and feed my Vegetable plants.

This is all you need.
The seller will also sell you the other ingredients, but you can find them elsewhere if you try. And at a much better price if you buy some quantity. Add Calcium Nitrate and Epsom Salts, and you have the complete formula. And it is flexible enough, if you know the math, to adjust this formula for most any growing plant and condition. But this product is the nutritional base and is absolutely amazing. A must have. I only wish it cam in a Can or a Bucket just for ease of keeping. A few desiccant bags in the bucket would be nice.

good but as with all dry salts you need to add calcium nitrate and epsom salts (magnesium sulphate)
you need magnesium sulfate (epsom salts) and calcium nitrate to make this complete. important.

Great Stuff but DO NOT forget to add Silica!
Masterblend is a great product and this is a great value. Almost all that is missing from this system of nutrients is a great source of Silica! Silica is the building block of plant cells. It is like the concrete in a building. It will give you thick, strong stalks, among other growth benefits. Here's the best Silica, in my opinion: https://amzn.to/2xBWeHF Add it after pH'ing your water and before adding the other nutrients. note: Be careful not to get it in your eyes! You will also need Calcium Nitrate, of course. Here is the best deal for that: https://amzn.to/39JB5JL Best of luck!
