First grow here, I've been reading quite a bit about the need for co2 during flowering. My bud room is 10x12, I will be placing approx. 6-10 plants grown in soil. Should I be concerned with the need for co2? I have been looking at the co2Boost. If co2 is needed, does anyone know where I can buy it online through a Canadian source? Being in Canada, purchasing in Canada saves a lot of headaches. Thanks for your input.
