re useing soil

Hi all can soil from previous grows be reused or should I buy a new batch trying to save some cash and soil is allready mixed with perilite.
Thanks

Spend your cash, any disease\pest\mildew\etc is somewhat likely to stay in your soil despite your efforts to disinfect it. Some may disagree, but I say this is an absolute no brainer... soil isn't expensive enough IMO.

Thanks will do
