Home made feeds

I set up a nettle press today, it's made with a 4ft long by 4inch diameter drain pipe wire mesh secured at the bottom as a filter and a empty wine bag fitted to the bottom to catch any liquid, I filled the pipe with nettles then put a 14lb hammer head into the pipe to act as a press, fitted a cap to the pipe then suspended the pipe from a tree, this setup works with comfrey, I have 3 or 4 lts. of confrey juice collected this way but do you think it will work with nettles?

I made a similar setup last year using a full pop bottle as the weight with a length of string tied on the top to retrieve. That was the Mk 1 version which didn't work too well because the pipe was too small a diameter. I have scrounged a larger pipe about 150mm/ 6 inches diameter and a metre/yard and a bit long.
Once I get on top of the rest of the plot I will eventually get round to fixing it to my IBC tank frame where I can get feed and water at the same place!
I have already had one cutting from the comfrey and it is ready for another. I usually get four or five cuttings from it per season.
