Vitamins A and C, iron, fibre, and folate are abundant in lettuce. Its 95% water content boosts everyday hydration. Anti-inflammatory, anti-diabetic, and cholesterol-lowering properties have been reported.   

Picking The Right Kind Of Lettuce 

Your lettuce seed-growing steps will vary by hydroponic kit brand. Overall, the approach is comparable. Always read your kit's instructions, since they may vary.  

Planting Lettuce Seeds In Hydroponic Kits

The supplied grow lights are a major benefit of hydroponic kits. For lettuce, keep the lights on for 10–14 hours daily. Keep grow lights an inch or two above seedlings and adjust as needed.
