Nutrient solution concentration is one of the most practical and effective ways of controlling and improving the yield and nutritional quality of crops for human consumption. The study was conducted to determine the effect of natural farming inputs as nutrient sources applied at different levels on hydroponically grown lettuce. It was conducted at Cagayan State University–Piat Campus from September to October 2019. A factorial experiment in Complete Randomized Design (CRD) was used and replicated four times using the 45 boxes with 8 plants in each planting box to test the following treatments: Factor A (Lettuce Cultivars) A1 – Leafy Eton, A2 – Leafy Red Solar, A3–Altima;  Factor B (Nutrient Management) F1-25 ml SNAP Solution (Control) F2–25 grams Master Blend (Control), F3 40 ml Kuhol Amino Acid, F4 40 ml Fish Amino Acid and F520 ml KAA+20 ml FAA. Based on the result, lettuce cultivars did not show a significant effect on almost all the parameters measured; neither was there a significant interaction between the two factors tested in the experiment on all the data observed except for the root length, which showed a significant result. The following recommendations were formulated, the use of Leafy V1 (Leafy Eton) in all year round lettuce production supply can be achieved using a solution from SNAP and organic concoctions (KAA and FAA) as growing medium for urban hydroponics gardening and a follow-up study on the higher concentrations on KAA and FAA as a nutrient source in hydroponics production is also recommended.
