Getting my starts timed right?/!

If I am planting outside but I want to start my seeds inside. How many weeks are ideal to have them in Lrg Red Dixie cups from emergence? I ask because I really don't want root circling and would like to have as large a plant as possible (Industrial Hemp). I am planting in virgin horse pasture, ground that has compaction and I am doing no-till.
For those reasons I don't know how successful direct sow would be.
Keeping in mind, I will be boosting the seedlings' growth with Ful-Power Fulvic acid. They will also get Mycos and other stuff when they see the ground.
Oh yeah, Does the lunar cycle refer to sowing seeds or transplanting? I can only assume sowing due to the lack of tech back in the day. . .

Depends on region. Also, just transplant to avoid root bound plants

No more than 3wks in solo cups. Transplant by then, either up pot or direct to soil. Daylight hours are still 12/12 until a bit into april so now is a good time to start indoors. I start on march 6th to march 10th. Then early april they should be ready to go in field

I just popped my summer grows.

They will be outside the entire time as nature intended.

I will leave my back porch lighting on at night until may 1st to ensure I don't confuse them.
