That's a lot of em hehehe. May I ask if you don't mind how long it would take for you to finish watering them? I think my collection is as small as 1/8 of yours and I'm spending about an hour or more watering them.
The collection is bigger now, so it takes around 30min with a hose. But need 30mins extra for rainwater on the Paphs.
But it can take upto 3 hrs when i fertilize using watering can. In that 3hrs i do pest checks and remove the unwanted leaves etc. I do this one a week.
