$150 for the timer and regulator, $10 a month for tank rental (50 #), and about $80 a fill, which would last you 2-3 months. You don't need CO2 though unless your running at least 50 watts a square foot. Better to invest in more lights, if you want to increase yield.
is there a light u can buy that sits on the floor...
instead of hanging another light is there one that can concentrate on the lower part of the plant..meanin a floor light ya'know thanks
well..im not sure if they make lights that sit that low for the purpose your wanting them for, but usually growers will just hang different fixtures lower for the sides and bottom. You could always trim the plants so you don't have to worrie about the bottom lower buds/branches and you can concentrate on getting bigger more potent top cola's
