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

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

Awesome value for money! The light green powder mixes well and easy to use. It lasted me over a year and its super effective for lush and hefty vegetables!

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 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!

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

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

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

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.
