it is my favourite system, using growrock and a good control res, when done right, eliminates most if not all root related problems, as the plants are growing in air, I strongly recommend it, personally prefer it over DWC because it needs less equipment and tubing, no airstones less humidity less things that can go wrong, it is very easily automated with a simple timer, recycling is also very easy and is very clean unlike coco or soil.
You know what bugs me about E&F ?
That big rez sitting there bubbling and being cooled and no roots in there eating except for a drenching every 2 hours or so... seems such a waste...
I'm trying a hybrid:
I want to recirculate (RDWC) 2 inches below the pots and every couple hours flood to the neck and back down again (E&F)
Maybe once a day empty the tray completely but most of the time, some roots are in water.
nutty?
maybe not. I SWEAR I noticed a difference overnight when I started ebb & flo every half hour with plant tray (5" air for roots below pot)
and rez both being bubbled
4 minutes to fill to an inch up the pot, drains in 10 , roots sit in air maybe 15 minutes before it floods again
