hey every one I'm in the growing business and very new to growing, I am building in a closet approx. 8' long and 3-4' wide, I don't have that much money and I don't have access to hydro shops or online shops just garden shops such as home depot and lowes etc. I have a water reservoir and a general idea of what i want to do.... I want to use a hydroponic system (making my own) and i have seeds already but I don't know where to get mylar or rockwool cubes without going online or a different country..... any suggestions for planting materials and fertilizers
