Changed back to 20/4, stacking pretty good, this is completely organic in super-duper soil of my own making other plants in pic are GSC auto extreme from ilgm and gelato from fastbuds don't know which ones which as I was stoned when planted and forgot to label so no diary on them.
Yep, you don't really have to wait for a 24 hour cycle. I prefer 18/6 though. I believe the plant having time to rest is beneficial although there's very little science regarding this.
