Wow I read the last few pages of the sticky on co2 and my computer started to bleed..so please dont stab my suggestions and experience.Lol just kidding you fucks.I used a green air cd-6 propane generator with a cyclestat timer for maybe 2 years or so.A cyclestat timer determines length and frequency of burn in accordance with cubic footage of the room size.I couldnt figure out why I was basically getting the same results as if I were growing with 350-500PPM,it was perplexing and a bummer.Then I acquired some knowledge about co2 enrichment and did some testing.I used RAE co2 testers at different times during the 12 hour period.The bottom line was my co2 fluctuations were too much for the plants to get any enrichment.It was as if I were growing under normal co2 conditions..Never used a cyclestat timer or any calculations of any sort,you must use a co2 controller to get real enrichment,period.The controller will only let the level fluctuate a couple hundred PPM or so which is optimal for true enrichment.My setpoint is 1500PPM,when the level drops to 1450 it kicks on my generator.My generator burns until it reaches setpoint(1500PPM) but the level normally rises to around 1600PPM.Thats only a 150PPM fluctuation for 12 straight hours and thats what it takes to increase yield 25-30%.That and R/O water,50 watts sq ft Hortilux HPS,a killer window air conditioner if using non-cooled vertizontals(the best flowering fixture going) 85 degrees F. at the canopy and a dehumidifier.I'm just not a fan of yeast and such methods because I used an actual burner but didnt achieve enrichment,co2 fluctuations and limiting factors are death to enrichment.
