I run "The Bucket".... It has an organic compound that brakes down and emits CO2 in a bucket through a pump and over the plants every 15 min alternating with my fans ONLY durning light hours... This system will run for 6 to 8 months (depending on useage) before a refill.... I don't waste any CO2 on vegging....PPM is around 1200 unless I have to deal with spidermights then I'll shut the fans down and crank it up to 20,000ppm for 1 hour and that will choke all the mites rite out!
HashHands Reviewed by HashHands on . CO2??? Flowering Now/ Temp Problem I have 47 PK plants growing is Sunshine Mix # 4 with 1/2 bag Peat Moss and 2 bags Perlite added. I use Safers Fish elusion and Mari cal Grow 20-20-20 . Lighting is 2 1000 lights. Plants are now 5 weeks old and are doing real well. I am putting them into 12/12 today. Is it to late to use CO2. I have taken 170 clones and the clones are doing OK.????? Should I introduce CO2 now, or forget it and wait until I plant the clones and start new grow.??? If I was to use CO2 I would use Coleman Camp Rating: 5
