Not even I'm confused What growing medium are you considering using?

For your first time you should just stick with dirt. Growing indoors is fine but use soil for you grow medium. The mix you are talking about is a little hard for beginners to balance the Ph and keep it balanced. Watch the heat it will kill your hopes fast if you let it get away. Fresh air in and hot air out of your grow area is a must. Donā??t over water use a meter so you know when to water and watch the Ph of the soil too.
