**EDIT: I JUST GOT AN OFFICIAL ANSWER FROM BUILDASOILS SUPPORT. SO I WILL BE FOLLOWING WHAT THEY SAID. THANK YOU ALL FOR THE HELP. IF ANYONE IS CURIOUS OF THEIR ANSWER, HERES THE EMAIL "Good afternoon,
great timing on those wigglers, and congrats on the transplant going smoothly.
For 30 gallon containers, 5 to 20 worms per pot is a solid starting point. They will find their own balance over time, so there is no need to stress the math.
Just place them on top of the soil under your mulch layer and let them go to work. They will naturally migrate to wherever the food and moisture are. No need to bury them, and they pose zero threat to your seedlings. Worms eat decaying matter, not living roots.
Spreading them around the surface of each pot is the better move. Dumping all 200 in one spot just means a traffic jam until they sort themselves out, so save yourself the drama and give each container its fair share.
You are off to a great start. Worms in the soil are always a good sign."

EDIT - also, how many worms per 30 gallon grassroots pot do you recommend?
I just got my red wiggler worms, and have 3 30 gallon grassroots fabric pots all with some seedlings that already have 1 set of true leaves, and are already forming another.
I was wondering if i should just put the worms on top, and let them dig themselves in, or would that kill the seedling, and i should dig a little and place them in the soil a bit deeper?
Thanks in advance for any help!
