Equipment need

How it's done

Before we start we have to make sure that we are having all necessary parts for growing lettuce. The parts that we need are:
- A pack of May Queen Lettuce seeds
- A sheet of rockwool blocks
- A water pH Meter
- A pH Minus solution
- A thermometer that can measure the temperature of the water and the temperature of the air
- A enough large transparent food container with cover

All the things needed in this tutorial you can buy at local garden or hydroponics store. Or if there is none of them around, you can find them on this Amazon list here: http://amzn.to/1TkwktC
