First indoor microgrow!

this is my first indoor grow ever . grow box is a 40x40x140cm tent. my initial intentions were to start with 2 auto seeds of +speed auto frow sweet seeds and then i ended up with 5 seedlings(other seeds found in weed so unknown) in a minibox 😂😂...let's see what happens. first seed germinated on 31/03..the others some days later. light at the moment is a low bufget amazon 50W COB LED, which i will replace with a easygrow miracle S100 100W, i'm having some troubles finding the correct distance of the lamp..in the first days the plats grew vertically in the search of the light and i had to do some LST to keep one low.
