what is your opinion on this? keep reading of conflicting ''rights'' and ''wrongs''
poviding a wooden viv is modified sufficantly with extra ventilation by either replacing some of the wood with mesh, or by putting lots of vents in the sides and the top it will work fine.
no one can realy say what is best for each person because although technicaly a flexi is better as it gives excellent ventilation, if your house is too cold it will be uselss as you will not be able to keep it warm enough, so then a wooden viv would be better option.
i use flexis because my house is very warm and it would be imposible for me to keep the temps down, and because im crap at diy LOL
