Hydro shops are the best.
Before being able to go down the street and buy what I need.
I used to have to drive to lA or SF or get it sent threw the internet.
So I'll gl;adly pay a little extra for that convenience.
If your going to do this.
You need to stop that mantality.
Growing and trying save money do not go hand and hand at first.
And it does always cost more then you planned.
I suggest you keep an open mind and save money if you can but don't skimp on your grow.
Like Zandor says.
"If you go cheap ,you grow cheap."
