I don't want to hijack any long drawn out disagreements here but i will say this...
I actually swapped over to hot with summer in mind.
Last summer was a complete pain for insect poo,pollen , snail trails and general baked in crap both from birds and the general poor quality of summertime air.
Going into my 2nd month of hot now and all i can say is am a very happy bunny, the results are much better and crap just falls off with hot.
I intend going hot all year,and allready my mind is made up, im never going back to cold
