Hey Rrog, you seem to know tremendously lot about organic soil. Im currently living somewhere where I cant get the fancy bags of soil. What I have at my disposal are: normal soil, perlite, humus, bat guano and dark peat moss. could you please give me the most essentiel do's and don'ts in order to reuse the soil and make it more efficient? Ive searched a lot, but most information conditions that I can get a hold of many more things, which really isnt the case. Im not trying to be cheap, I just want to make the best of my setup with whats available.. my plants are going into flowering in about three weeks.
