What is the best ppm/co2 level some say 1400ppm others say 1800ppm

All your help would be great

Well here's another and probably the most advised and used,1500PPM.Whats more important than 100PPM or so is a lack of fluctuation,you want it to fluctuate no more than a couple hundred PPM either way,For this a controller is necessary

1400ppm

To give an example how my cap PPM-3 works I start by setting it at 1500PPM.If the level in the room drops to 1450 PPM (50 below setpoint) it turns the burners on.The generator remains burning until it reaches 1500 PPM then it cuts off.This takes several minutes of burning to go from 1450 to 1500 because it starts to raise in very small increments,then after a couple minutes it'll go up 25 PPM every few seconds or so.Anyway,it cuts out at 1500 PPM but continues to rise to narmally around 1650PPM before the slow drop down to 1450PPM where the generator kicks on again.The room is experiencing no more than a 200 PPM fluctuation at enriched levels for 12 hours straight,priceless.Of course you must have at least 50W sq ft and a way to control temps humidity and odor before considering a sealed co2 flowerroom
