My question is how do I do a res change without shocking the plants with ice cold water

Get a large barrel or water butt and mix your fresh nutrient solution up in there and let it reach the desired temperature, or heat it to the desired temperature. Makes for quicker res changes too.

Thanks Billy I can get my hands on some 180 litre blue barrels so will rig one of them up.
