The plants won't really need any extra Co2 until they are flowering. But it won't hurt... And a good tip is to use alot of sugar... The more sugar you can use the longer/more the yeast will make little bubbles. Yeast and sugar water is a good alternative to expensive CO2 generators and it has the added benefit of making high proof alcohol.
