What up gc this is my first grow my light setup is a 70w HPS. Im using FF soil. My box has 1 outake and 1 intake just computer fans. It popped ground on 4/20. I havent used any nutrients just plain tap water. My screen is made of fish line. The seed was a bagseed of some so called "bubba kush" it was fire though. I dont know my temps yet im working on that but it seems to be doing just fine let me know what yall think.
