Welcome to [LGM We will help you through your first grow the best we know how that’s what we are here for.
Ya bob31 is correct about the floor…good point bob !
Then there is ventilation how will you bring in fresh air ?
air movement ( Fans )
Seeing how this is your first grow. i would advise you to start small say two or three plants to get started. i’m sending you my link to my journal on Auto-flowering plants and you will see what i have.
I’m sure you’ll have more questions and thats fine we look forward to it.
