4-18-38 Tomato & Vegetable Fertilizer - Bulk 1, 5 or 25 Pounds (1 Pound)

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

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.

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

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

Masterblend helped my garden grow and produce a beautiful crop. Will use again.

Works great!

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.

For better growth I noticed I had to keep increasing combined solution amount (Masterblend, Epsom Salts and Calcium, mixture A and B). I'm trying on greens, with some success. They grow very slowly and not as vigorous as planted on soil, though being pest free is an advantage. PH level was perfect though leaves of greens got smaller than expected. I guess the mixture needs to be stronger or something else is missing.
