I expect this may have been asked before but couldn't find it.

I would like to set upo a gravity fed, automatic watering system for my greenhouse, for when away from home. Has anyone any experience or advice about this please?

Yes, if you get onto ebay you will find the drip systems very cheap, it is worth putting an inline filter from your waterbutt, if your not using a waterbutt and getting something like the big dripper the higher the water the better.
