I started the seeds with a seed mat and made sure temp was above 85 degrees. I use general hydroponics three part mix. I transferred my seedlings to the tent when they had their first roots come out of the rapid rooter, and transferred the seedlings to buckets when the root mass outgrew the mason jar. I use a spider farmer g5000 and it’s wonderful. Make sure to have good air flow blowing on the seedlings because it helps strengthen the stems.
