JamesC said:Decided to give this auto dosing a go. Had my eye out for a peristaltic pump for some time now but have always been a tad expensive. Just brought this peristaltic pump 24V DC nutrient dosing water pump which looks like it will do the job. I've got a 24V DC adapter and a digital timer as well.
EDIT: Just noticed they have put the P&P up. I paid Â£5.00 and it's now showing Â£8.30.
I've been looking at those but they seem rather large ish, would appreciate a photo when you get it setup.
