A I dont know if that pump will work, but I would b trying it since it was free. Jus make sure to make it so u can change it out, encase. I saw the video. I aint never really seen anyone do it like he did with the top drippers. I find that interesting so I aint gonna tell u not to do it, but if you are gonna run that I think you should find what nutrients u gonna use, how your gonna run the nutes...and how u gonna keep them nozzles from clogging. If I was u I be looking into that asap. Check out some logs here good shit on aeroponics, though alot of these people are doing higher pressure u might run into some usefull info. I be looking in from time to time too.
