I have an old cooler I want to do a micro grow in. I can only do this during winter months due to the fact I live in an apartment complex on the bottom floor. The closet is outdoors on my fenced in no gate patio. I am concerned about airflow and an going to use an aquarium pump to pump air to plant canopy. I want to get advice on a good organic soil. I have one in mind andI have access to everything I need from a bro that has a larger grow. I am going to run an LED light also provided by my bro. I am going to plant onions and garlic outside the closet to cover any smell. Any thoughts on this grow or advice would be appreciated.
