1st grow ever | Outdoor / Indoor

I was ready to build my first indoor growing system. Growing my first lady ever! And then Covid-19 appeared and broke all my life projects lol. Confinement... Time for gardening, growing veggies, flowers.... And some weed ! My current situation don't allow me to spend any money on any setup, so this will be verry basic. I'll be thankfull to nature for whatever i get from it. Sprouted last night (Seed in the pot -> lightly watering -> first leaves in 72h). She's enjoying the sun for the first time of her life right now :) I will have 100% sun and good temperatures for the next days, so this should make her happy. She will be outdoor in a 10L pot, from sprout to harvest. Using basic soil from gardening store. As i said, no budget, and almost impossible to get specialized soil these days.... I will try to give nutrients made by myself. Any recommandations about this will be really appreciated. I'm preparing lentils juice right now, should be ready in 5 days. A bit late i guess, but will be good anyway. Nothing more will be added until flowering i guess, the soil is verrrry rich i believe. Except if she show some deficiency. She will have like 12-13 hours of sun everyday (up to 15h in one month) (with a big sun, as i'm living in altitude), and she will spend night inside (Outside too cold at night for now) I might turn this into a greenhouse setup, if i receive the tarp I ordered... Update Day 5 : - Adding some of my lentils sproot juice in the watering of the day (10%). - Been abble to order a fabric pot of 30L. I should receive it between day 13 and day 20. This been suggested by Ukexperimentalist, thanks to him. I will be verry carreful to avoid any stress for the plant during the transfert..... 😶
