Probably the biggest problem with drip is channeling, which is where water travels where there is the least resistance.
There is a high probability that much of the grow medium does not get equally wet. I tried to compensate by using Hydro Halo drip rings, but they built up algae inside and clogged
I gave up on drip.
I used to dtart seeds/clones in bubbleponics, but this grow have moved to lpa. Once roots are sufficiently large, I move them to my F & D totes.
