Nice thread Dex!!
Well ... I water by hand every day. I make up my batches of feed in a 5 litre water bottle.
I use Canna Coco A&B, add the A first and shake shake shake - and the B and again i shake shake shake (it's actually my exercise routine as well as my plant feed) and then i carefully PH and add a lot more shaking.
I've only got one plant - she's quite big now with approximately 3 weeks left, so I'm currently giving her 1.5 litres. I check the PH every time, becuase over a few days it will creep up a point or 2.
I absolutely agree with not letting her dry out ... but last week my girl didn't drink enough and this made me mad. She got punished with no supper that day and ever since, she's been drinking like a good girl.
I'd say fair but firm! ^_^ lol
It takes me about 3 minutes to totally water her as i'll water slowly and make sure every bit of the pot gets an equal share .. even the corners

then i'll sit and stare at her for 10 minutes, taking the odd dead leaf away from the bottom.
Pot size is about 10 or 11 litres (square plastic pot - i've gone back to them after trying airpots)
