Ive ran connie at 1200ppm + additives and didnt get burnt. My co2 levels were 1800 with a matador controller. in a sealed room. Unfortantly a seal broke around my window and was left unseen for a week. I put a 2x4 frame around the window frame with a couple sheets of black and white. I couldnt screw the top in cause there was no room for the drill. So I tried to staple it with a air gun. but the force of an Portable A/C and an 8 inch fan broke the seal.
It leak and cause major heat problems. I was running cooltube and the exhaust from the a/c. If the lights wernt so close i could have saved them. I had the lights so low cause of the shades i was using. I also had an 8 inch fan for the four lights. I still got 4.5 pounds of decent herb. I had so many empty canopey space tho. I only had 40 some plants under the four lights.
I think the ghetto setups work better tho. Big fans and less chance of failure. You can keep it consistent with thermostats and a/c. But no where near a sealed room.
Nice comparison. I didnt think juice really made much a differnce considering its all the same elements. Its all the about the ratios. The DG looks white compared to the connie that looks green. Also the tops are more round.
