i forgot i wanted to say something about the media mix. i did not dump the medium after the last grow. i was able to pull the root balls out and shake them off and so recovered most of the perlite.
i added 6 more lbs of worm poo and some more vermiculite and DE.
this increased water retention and so i have adjusted by going from 1 min every hour to 1 min every 2 hours. still delivering about 4 gals per event.
the new media mix feels moist to the touch at the surface at all times but not soaking wet.
the recirculating is happening without restriction.
i'm still using the jack's 3-2-1 formula with fulvic and kelp. reading today 1040 ppm at the .5 conversion and ph was 5.8.
