Looking for advice
I am a special education science teacher and I am looking fro a hydroponic system/design that they can build and maintain. We have a space in the classroom that is about 7x10, so I'm thinking soemthing vertical? I have never done this so it will be a learning experience for me as well. We are looking at growing spinach, I read that's the easiest? Can anyone offer me advice? I need a list of things we would need to purchase: growing agents, fertilizers, really a lost of everything we would need. I really appreciate any help or website recommendations.
