Without slinging shit... I am of the opinion that ebb & flow buckets will have similar results to ppks. I plan on doing both. I'm still undecided on the medium. Perlite with some screen and rocks to hold it down sounds appealing.
Intense growth rates... psh... Imagine being able to control the humidity on point because you're not exchanging the air as much as possible to drop temps... Oh wait, you know about this already...
Two things.
1. PPK vs Ebb/flow, likely similar growth/end result, but the PPK has the advantage of a larger media container to save your plants in the event of a power outage. More important for the remote grow or vacation time, but still a valid consideration. Plus the top fed flood cycle ensures you won't get that layer of salt buildup on the top of your media.
2. Yes I know all about this already Sealed FTW!
