It is my understanding anything over 830 PPM is toxic to the plants. I've had the same bottle of water, sugar and yeast in the tent now for two weeks. VIDEO to follow.I was under the impression you needed higher than that. But still my questions remains.. Say both rooms are equal except c02 supplement... So ones the 400ppm you say is common atmosphere, the other is with a supplemental say even 300ppms.. So the room is 700ppms... The 400ppm and 700ppm will produce the same? Everyone's saying unless your doing it right it's a waste of time.. But why wouldn't even adding 10ppm help the room? Is it just egos at play here or would the plant really not react?
