Masterblend 4-18-38 Hydroponic Tomato and Vegetable Formula

FLASH SALE!

Masterblend Hydroponic Tomato and Vegetable 4-18-38 formula is an all-purpose nutrient formula that provides plants in a hydroponic system with essential macro and micronutrients that plants need to grow, bloom and set fruit.

The tomato formula is a good, general purpose formula for a variety of vegetable and flower crops -- and even houseplants.

Hydroponic application:

We dissolve Masterblend Hydroponic Tomato and Vegetable 4-18-38 formula in pure, low-T.D.S. water at the rate of 1 pound of fertilizer per gallon of water. We then add magnesium sulfate (Epsom salt) to the solution at the rate of 0.6 pound per gallon of water. This becomes Part B concentrate in a two-part, A-B nutrient formula.

Dispense Part B concentrate into your hydroponics reservoir at the rate of about 1 ounce of concentrate per gallon in the reservoir after you have added 1 ounce of Part A concentrate per gallon of water in the reservoir. Mix thoroughly and check the nutrient levels in the reservoir with an EC meter. Continue adding equal parts of Part A and Part B until you reach the desired nutrient level, usually 2.0 EC or 20 CF.

For making your own Part A solution, refer to the hydroponics application section of the description of Calcium Nitrate.

Masterblend Tomato Formula Fertilizer is well suited for soil growing, also. The formula completely dissolves in water with no fallout and won't clog sprayers or automated fertilizer delivery systems.  Maximum solubility:  3.5 pounds per gallon of water.
