Yes I agree with gd the only way to use co2 to its full potential is having a sealed room and only exchanging the air once every hour or so . I have everything I needed to go big with co2 I just can't set the ac up properly I only want it running when the lights are on and off when the lights are off but I can not program the ac and if I try to run it with a timer once it switches off it will not switch back on . I would have to physical turn it on every day . Which I can't . Bar I bet them pots didn't cost you much not even £4.50 . and I'm loving the garden
