can I grow HC in a 20g with a 55w CF bulb? I will have 2.75 watts per gallon, but it has really good reflectors. So can i grow HC with it?I will do 2 or 3 bottles of diy c02 also. Thanks!

Make sure you also dose macros and micros. It will be fine under that lighting.
yeah I have never done hi tech tanks before. only low tech with no ferts lol. Do you know where i can buy dry ferts like csm+b?
Greg Watson Dry Ferts are recomended. You can also do a search on the site for Dry Ferts :)
Eh, dose those dry ferts and a little Excel now and then. HC loves Excel.
