i set them up properly. adjusted them at the dripper properly, compacted the soil around the carrots, syringed water into the caps, screwed them up underwater and left them there etc etc. it was all done as per thier instructional video, a number of times. i had about 20 of them, 1 in each 8 litre pot. random pots causing issues so it wasnt the set up. maybe i was just unlucky but after a fortnight of continually flooding, resetting, re-soaking etc i threw them in the bin and got a timer and pump. it doesnt flood my room out like these things did-frequently.
i re-soaked them at least 2 or 3 times. they caused me nothing but problems.
like i say, maybe i was unlucky
