Excellent!
I've been using this for the peppers in my hydroponics system. It's easy to mix and the peppers love it!

Excellent nutrients for Kratky method hydroponics
I use this blend with my small scale Kratky hydroponics system. It's very effective at supporting plant growth. Easy to mix in a five gallon bucket, it lasts a long time. I grow mostly lettuces and tiny tomatoes and this nutrient solution under a grow light and this assures we have fresh salads all winter long in Ohio. I've noticed a lot of Kratky method growers use this brand, and I can see why.

MasterBlend produces excellent lettuec
MasterBlend 4-18-38 produces lettuce with normal growth when used in a hydroponic solution. At first I was skeptical about this formula because of the low nitrogen ratio. I prefer a balanced formulation. I tried this product because of the exhaustive list of micro nutrients and I'm happy with the results. The lack of a single micro nutrient can spell disaster for a crop. Did not use Epsom salts as recommended on the package. Thanks to manufacturer for specifying dilutions in teaspoons and grams as I don't have a gram scale. Hydroponics is an excellent way to produce salad vegetables in a small space for your family. I've been using this growing technique for thirty years and I've experience with many products. Highly recommended!

Works great but pricey
I think it was a bit pricey but it does dissolve completely and would work great for hydroponic gardening. I had some questions about mix concentrations and the person I talked to on the phone was very helpful

MasterBlend 4-18-38
Es un excelente compuesto de abono que ha mejorado el desarrollo de la planta, tanto en floración como en sus frutos (hortalizas); lo mejor de todo es la cantidad de micronutrientes que son necesarios e indispensable para el desarrollo de las plantas, principalmente usados para la cocina.

Happy plants
If you follow the directions and weigh the salts, one gallon of spring water has a EC of 1.4.
