What is 2 Stage Lettuce Feeding System ?

NutriHydro’s Lettuce formula is designed to provide nutrients for roots and stem development. This is very important in growing lettuce crops because the health and lush of roots will lead to equally lush and thick overall lettuce vegetation. The success of many NutriHydro users who have grown the largest and healthiest lettuces in the Philippines is based on the foundation of this nutrient design.

Two stage feeding for lettuce crops is a system that differentiates feeding at seedling and at growth stage. This tweaked feeding system adapted to each stage increases the potential ability of lettuces to grow at its largest and healthiest possible state. The first stage otherwise called as the Foundation Stage, focuses nutrients for roots, stem growth, and the overall health of the plant. The success of crops grown in enthusiast and commercial farming both rely on their ability to produce the best seedlings possible during the foundation stage. In fact, seedling management in commercial greenhouses are grown and managed in a completely different system. A not-so-perfect seedling production leads to an overall challenging crop cycle. Manage your seedling well and you ace a crop cycle.

On the second stage, the lettuce crop enters the Growth Stage. At this stage, your lettuce crop must have grown the proper amount of roots, the maximum possible stem girth, and a few foliage sized around 2 to 3 inches. When you have seen such, your crop has just entered the growth stage. At this point, the nutrition being fed to the crop will have to be re-dosed to enable the crop to have the sufficient energy it needs to grow its foliage.

HOW TO DO IT

FOUNDATION STAGE

Foundation stage is defined as 10 to 20 days after sprout. At this stage the formulation of NutriHydro’s nutrients are focused towards rooting, stem growth, and over health of plants. It is important at this stage to develop the foundations as best possible as you could. The success of an entire crop cycle depends on the success of seedlings.

  1. NutriHydro Lettuce Liquid nutrient solution: Including the hardening stage, feed the crop by using equal quantities of solution A and solution B diluted in water no more than 850 ppm. Follow the instruction on the label, no change at all. 
  2. NutriHydro Lettuce CFF dry form formula: Dilute 10 grams of calcium nitrate, 7 grams of NutriHydro Lettuce N PK, and 5 grams of epsom salt all in 16 liters of water. Follow the instruction on the label, no change at all.

GROWTH STAGE

The growth stage for lettuce is defined as the age where it is genetically ready for foliar growth. This is usually after the seedling stage, from the 21st day onwards. At this point, the lettuce is genetically predisposed to grow. With proper water, air, light, and nutrient management, you can expect your lettuces to grow as fast, as big, and as healthiest as it could be. The essence of feeding at growth stage is to provide high levels of nitrogen along with balanced macro and micronutrients to fuel the growth of lettuces.

  1. NutriHydro Growth Nutrient: Use 2 mL per 1.5 liters of water. Mix in your nutrient tank along with your solutions A and B. When all combined, the TDS should be no more than 850 ppm when measured. When going beyond TDS 850 ppm, be sure to trial in small batches before using in your entire system.

DO YOU HAVE TO CHANGE THE FINAL SOLUTION WHEN FEEDING ON THE SECOND STAGE ?

The answer is NO.

In any hydroponic system, upon topping up, just dose the nutrient tank with prescribed instruction in feeding at growth stage.

ADVISE TO TRIAL

As do any responsible and experienced growers do, use the 2 stage feeding for lettuce system on a trial basis first. Do not use NutriHydros 2 Stage Feeding System on your entire system until you have successfully used in a small batches. In performing trials, journal your experience and include information such as pH, TDS, water temperature, water flow rate  (if you use systems with moving nutrient rich water), humidity, description of the amount of sunlight received by the plants, and windy information. All these factors affect the growth of your plants. By consistently journalizing your crop growth, over time, you will begin to see patterns of what works and what doesn’t. Journalizing enhances the quality of your experience.

THE FINE POINTS

  1. The increase in doses of growth nutrients can cause nutrient burn. It is very important to keep a keen eye on signs of nutrient burn. The usual signs of nutrient burn are are yellow and brown burn marks along the edges of leaves, cusped new leaf growth, sudden stunted growth, and an unusual deep green color in the foliage. When you encounter such, dilute the solution down by adding water to your nutrient tank, give the crop time to heal, and you will be back on track in no time at all.
  2. In feeding you lettuce crops at growth stage, there is no need to change the entire solution in your nutrient tank. Just add the growth stage dosing at the second stage without going beyond 850 ppm. The same reminder goes that going beyond TDS 850 ppm requires that you trial in small batches first.
