They need regular watering - not too much, not too little, just constant - also temperature changes can cause splitting, is your GN well ventilated, shaded?

yes it's open all day on warmer days and closed in evening..

Irregular growth pattern = splitting tomatoes. Hot day, cold day, hot day, you're fighting a losing battle against the British climate. Make sure the tap roots have a water "reservoir" for constant supply (very difficult if using growbags ).

I suspect it's the weather, not you. Annoying though. I do find that some varieties are worse than others. The otherwise admirable Sungold is a beggar for splitting.
