Gonna take ya`ll waaaaay back ta krusty bucket school when the end result in the rootzone was a constant "nutrient rich fog" like D9 stated from Lucas speak back in the day , but it was and still is a complicated system to re-create just for the benefits with all the bells and whistles it took/takes to dial said setup....but...
Rootzone air porosity was based on the lava rocks we used that were boiled and tumbled regular to prevent silt and sediment while maintaining all those irregular edges and sizes that held O2 in the rootzones constantly while the big bitches were fed at a trickle and recirculated 24/7/365 with monsters using the right hybrids...
People were amazed at the size plants it pumped out with the proper 50/50 hybrids tailor made for the system with jacked up ppms and weekly flushes to control lockout while jamming nutes right back up their ass to make em jump with proper watts per sq ft and environment.....that said....
Why ANYONE would chase the dragon with krusty buckets SWC or the RDWC reasonable facsimile thereof these days with chillers and air compressors , plus the rest of everything needed to control environment is beyond me since the onset of a decent understanding on PPK`s and their ability to grow big plants and keep the majority of the plant`s "rootzone" as "air roots" above the juice with only a small percentage of remaining rootmass deemed as water roots in the lower container with nothing but bare minimum equipment.....anyways....
My 2 cents from all them yrs of fuckin up and finally getting it right....
D9...Respect...and...Happy Turkey Day....
Peace....DHF..........
