Hi Polcho, i have been brewing for 2 years with no temp control with no problems other than one's i have created, as Foxy says above brew it and build on your gear, i have just bought 2 corny kegs and a pub style gas bottle still no fridge but that will be sorted in a couple of weeks, up to now i have never cold crashed as such but have made some great beers kits and ag i do both, so my advice would be to just brew it and enjoy doing it
