Fill the grow box approximately with 12 Liters of water (distilled, or tap water is fine as long as it is not contaminated).


Check the pH level of your solution with the pH meter. If it is within 5.5 – 6.5, the nutrient solution is right.


Place the net pot with growing media of your choice, and seeds into the rockwool or sponge.

Plant the seeds into the net pots pushing them through the rockwool or sponge at around 25 milimeters deep


Add half strenght plant nutrient solution after a week. You don't have to bother with nutrients on the first week as the seeds get the nutrients they need from their cotiledons.


After two weeks you can go full-on with the nutrient solution following the instructions on the label of the brand you have chosen.

How Kartky Method Works

Hyrdroponics Tips:


For users who want to ensure maximum yield from lettuce crops, it is recommended to use a TDS meter. TDS is short for Total Dissolved Sediments Meter. It is used as it is called, to measure total dissolved sediments in water. Doing so gives you a guide n how much nutrient solution is in the water. It is recommended that you use a TDS meter so you can measure objectively and eliminate guess work.



It is a must to use a PH meter. Lettuce needs water with NutriHydro and NutriPlus Letttuce Formula to read between 5.5pH to 6pH. Going below 5.5pH will lead to macronutrient deficiency (NPK deficiency) and stunted growth. Going beyond 6pH will lead to micronutrient deficiency (trace element deficiency) which leads to burnt tips and causing the crop to turn yellow and lose its health. As it is so said in hydroponics, "pH is the key".

Once you have tested your pH, you will need NutriHydro pH Adjuster to dial down your pH to the correct range.

NutriHydro Plant Nutrient Concentrate for lettuce is a superior product which users find better than other known solutions in the market. NutriHydro Lettuce yields more quantity and superior quality when growing lettuces because it is specifically formulated for lettuce.
