ok basically i bought every items required to grow indoors, no im not wasting money, i have spare doe to waste so i might as well buy growing equipment. i have 4 CFLS 100watt (B&R), a normal fan just blowing air which also creates a vacuum that removes the air and brings in fresh air to my hydro system. im growing 4 AK48 autos but i really need advice on the soil to use. i have research alot about growing on this site and other guides but the only issue i have is buying the right soil. since all these Fox Farm and s*** like that is not available in the uk, i have only few options of soil to use and the most locally available is miracle grow! im wondering if its possible to grow with potting soil or do you need to mix it with something else? i also have multi-purpose compost but the only issue i have is the fact that i dont have a clue to wether you need to mix the soils or can use compost on its own or potting soil? what are the best to use for autos? please help out a noob!!! p.s and yes i have searched this forum but i cannot find the answer for my question (maybe im not looking far enough but i cant be asked) and my question will just make it more easier to find an answer for people who are looking for them!
