What the heck is it with newbs and miracle gro?
FUCK MIRACLE GROW, you dont want that shit so get rid of it and buy some real soil + fertilizer.
Just to let you know those lights arent cfls, they are normal fluorescents, and its a good thing you switched as a house light will not have hardly any growth.
google compact fluorescents to find out what youre looking for.
Get rid of that miracle gro it sucks and that time release part of it will also mess with your plants.
