Keep it in the soil, transplant to a bigger pot in a few weeks. Learn the "normal" way to grow this plant first, then branch out to complicated fancy methods to improve yields or whatever your goals are. If you're in it for the long haul it's worth taking your time to understand the whole process from every angle possible.
Looks like a fine start. More light, and a bit of airflow soon, and you're on your way!
Thanks for the advice, I like your rationale. I'll go pick up some larger pots this weekend. Move it from the windows to a closet with some LED lights.
If you have LEDs those will work nicely (just gotta fine-tune settings and distance). Pretty much any light source can be made to work though! Gotta love this plant.
If you need info on making organic soil mix (as opposed to buying a premade product) then please reach out. You'll learn a lot either way I'm sure. I'll follow along to see :)
