Howdy colliefish,

I've always thought,that co2 would not be very effective,if you don't have the light intensity,to take advantage of the increased co2 levels. So,if ya don't have 300watts or more ,of high intensity light,then you're not really gaining much...am I wrong ?

Would co2 help in a low-intensity grow ?

Have a good one...Torog
