hey dude, here is my setup.. im growing for the same exact reason... I HATE BUYING THAT SHIT..... This exact setup here cost me 45 bucks (no joke)
its in my closet... i just changed the pots and soil because the soil i had before... (since i didnt know better.. ) i used backyard soil.. i was like shit... look at all the weeds growing back here.. im sure this WEED will grow in this too..
But it didnt grow very well... too many pests, very low PH and the soil was getting to rock hard and the roots couldn't move.. i was forced!
