I always say yes to worms, but no not needed. If you apply worm castings, there is a good chance you will have a cocoon or 2 in there, and they will supply a few worms. There should be plenty of life in the soil without worms.
I run wicking setups a little differently. I don’t feel they work well with just bottom watering (unless they are real short). It’s super important to keep the layer of soil just below the surface moist. It’s where the most life is. I top water, and let the run off flow into the res. Then if I think I need more water in the res, I add some more.
I start with just a thin layer of water in the res when plants are small. The thin layer should just about disappear in a day. Then I just maintain that, in between top watering.
With a fresh sprout in a 10 gal, I won’t top water for around a week, and just maintain the thin layer in the res. By keeping the layer thin, it will help you control accidental overwatering of a young plant.
When plants get big, I top water more often, and maintain a deeper water level in the res.
Another option to top watering is misting the soil. But it’s way more work.
After ya make your first run in this soil, remind me and I will gladly help guide ya thru either a notill cycle, or recycle/reamending with this soil.
