Hey, Im about to start my first Pc Grow and only intend to grow about 2 plants for personal use. The first thing I need to know is if my old computer is available for conversion. It is an old Dell computer and has a weird slide opening to the case so could you recommend me about what to do about that, and if it can be used?. Could someone also link me to a suitable guide for conversation and suggest some possible things i need to do, purchase etc. Finally, some possible strains which are small, not too smelly and not that expensive and easy going for new comers! Thanks!
