@TheGreenYeti I use Happy Frog for soil. I kept clones in the plugs for 30 days last run no issues, no trimming of roots. Roots just got to be 6-8 long. If it looks like they won't fair that long I will throw them in some solo cups for a couple weeks. Most of the 21 are destined for the chopping block, so I'm really just being a cheap bastard and not wanting to waste any unnecessary soil. Plus I always feel bad killing plants once they are in soil. It's like I gave them false hope of the good life just to snip their heads off.
