I Just Started Using Co2. I Was About 3 Weeks Into Flower When I Started And Now Its Week 5. I Cant Say Ive Seen Any Super Huge Gains Since I Added It. I Have Mine Regulated To Go Off With Lights And Exaust. I Add 6 Min Every 40 Min On Setting 5. My Room Is Almost 800sqft And That Putts In 1000 Ppm Every 40 Min. I Had 35 Plants And Now 21, Fucken Hermies. I Figure They Use At Least 500ppm In An Hour, Right? I Assume My Room Doent Recieve More Than 2000ppm At Any Time, If U Account For Plant Usage. My Rooms Pretty Sealed, I Just Keep Air Coming In From Out Side, The Tarp Around My Flower Room Looks Like A Huge Bubble, Its Awsome!
Should My Buds Be Huge Already? They Are Like Half My Forearm Right Now So...
