that's the thing...printer....there' a relatively small learning curve, to growing quality bud, and a few crops under your belt is basically all you need before you will figure it out....
I personally went with " living soil organics" right from my first crop,,,,since I had done a lot of reading in the grow sections of this site....
and thought for me at least..... this method made sense...
I think of it as feeding the microbes in the soil, rather than feeding my plants.....I let the microbes do that....
and the plants in turn thank me....by growing quite well.....
