dont use time released miracle grow soil
if you do, you might be very sorry later... the problem with time released is that you cant control it, it is released when u water
but what if your plant is getting too much nutes? then what? u cant water for a while?
well what if u water too much? not only do u have the water problem, but u also have all the extra nutes being released
what do people do when they burn there plants from too much nutes? they flush with water.... but guess what? you cant flush with time released soil, you will just be releasing more nutes
if its all you got, then i guess go for it, but it could be a major let down after all your work, and you start lovin you plants, then next thing u know, they all ded
