So I came across a co2 tank with regulator and a Titan controls timer on Craigslist for 50 bucks. Tank was empty when I got it but only cost me $35 bucks to switch it for a full one at my local hydro shop. Now the thing is I've never used one of these before. I need some help. My room is 4(W)x7(L)x9(H). I'm running 2 600 hps bulbs in air cooled reflectors, 10,000 btu a/c, 2 fans for air circulation, and 1 260CFM inline fan with carbon filter connected to cooled reflectors. What should I set the regulator to? And also, how should I set the timer to release the co2? The timer has 15 minutes trippers. Any help would really be appreciated. I will be starting an indoor grow journal very soon. Hope ya'll can follow me onthis journey. ..:: Be Happy, Stay Stoned::.. Sent from my Z813 using Tapatalk
