so for a 50l bag add 50g of dry water retaining gel (50g = approx 10

I've purchased 1kg bags from Ebay for around £12.50 - there a few
sellers at this price.
Thanks for the pointers on how best to mix/use the gel. I shall pass these to my wife as that will be her job

The only gel I found that specifically states it's suitable for edibles was the Westland Water Saving Gel. The others either specifically stated they weren't suitable for use with edibles or didn't say either way. I picked up a couple of bags from Amazon:

They currently have it at 3/250g as a filler item (free with delivery's of 20+), incase anyone else is looking for some. Was the cheapest price I could find.

I have one dripper per pot and each is adjustable. You can make out the orange drippers on the first picture. I hadn't wired up the second one when I took the pictures.

Micro irrigation seems to be relatively cheap these days so I thought I may as well do one dripper per plant. That way I can adjust the flow independently.

middle of the night.
This is useful info for a novice It gives me a good starting point and I can then adjust to my own conditions. I guess you just have to keep an eye on the plants/soil and vary timer or the dripper periodically.

Fortuitously AMEX sent my wife and I 25 off 40 spend codes for Amazon. So I grabbed the Orbit HF Buddy II:

After the code it was 15.99

I used my wife's code for the other bits I needed to complete the setup. I'm sure the 50 saved will just go on plants instead :/
