I am curious to know how difficult it is to grow while using nutrients. I want to grow just with soil and water, but I know that it will hurt me on yield and potency.

So, I was wondering if anyone could help me out in regards to what nutrients I could easily obtain and easily use.

I will be growing Top 44 under 175w HPS in a grow tent.
