How To Grow Your Own Lettuce Using Solo Cups In Your RV

Fresh lettuce is a great ingredient to have on hand. The delicious and nutritious leafy green is so much more than just salad. You can use it to make wraps, sandwiches, burgers, juices like V8, or even into a creamy soup (it’s true—lettuce soup is a French classic, and it’s absolutely delicious).

Most people pick up their lettuce among other produce at the store or local farmers markets, but it’s surprisingly not very difficult to grow your own—even in tight quarters.

Every morning, he watered the plants by pouring this solution in the cup underneath:

  • 1 gallon of water (PH between 5.5 – 5.9)
  • 5ml of Mag-Cal Solution
  • 5ml of FloraBloom
  • 5ml of FloraGro
  • 5ml of FloraMicro (a three-pack is available on Amazon)

For his set-up, he shared these photos of the fluorescent grow lights he used. They are rather large, but there are smaller lamps you can get online that will still give your lettuce plenty of extra light to grow inside (like this portable growing light that can be powered by USB).

The best part is that it’s so sustainable. You can harvest the lettuce or clip off the leaves and eat them however you’d like up to 4-6 times before the plant starts withering away. It’s a fresh, wholesome gift that keeps on giving!
