Use potting soil. Some guys switch over to hydro, but I don't think I ever will.
I do it the easy way.
You want an organic potting soil that isn't hot. That means getting a quality product.
There is a bunch, I am using a product made for pot, but when it's gone I am going to
switch to a locally made organic potting soil. The easy way would be to start with a soil
made for growing pot, and then later switch to something that is still good but cheaper,
or to make your own. There are several recipes here to make your own potting soil. Ask here before you buy it (unless it's Happy Frog)
and we should be able to tell if it's good.
You will still need nutes, at least for the flowering phase. You have a bunch of choices there.
One cheap choice is Grow More Sea Grow Hawaiian Bud and Bloom. I use the General Organics
Go Box. There is a lot of others. Everyone has their own take, I am in the process of coming up
with my own right now. I know it will have liquid fish fertiliser, HEY, it's a start
Tell us about your plans, what's the grow space like, the lights, which pot containers,
ventilation and air filtration method.
This is all a bit intimidating, but we'll help you get started. The first step is don't talk
about it, unless you're in a state where it's legal.
