Is this seedling going to survive?

Pray for it Ive had one like this The top just fell off (Give it more light and try to keep the moisture high)

Let me guess. It went without light As its face hasn't even turned up towards the light Okay. So that cup will lessen its chances. No natural air-flow around the stem, high RH. NOT GOOD MATE. If u in a tent Wet towel hung on your tents bars will be better.. If it keep stretching. You can make it smaller by bending the stem, and lowering its height (there's other ways also dm me if u want) And get between 12-15k lux onto that seedling. After its out of that stage. 20-30 until wk 3 and up it if needed.

too earlay to tell but looks like part of the story is missing. why is the top bent at 90degrees? also, these are in a huge pot. i see you watered just the centra area of it... this is fine, as long as you made sure it got wet all the way to the bottom. If not, you could unknowingly being drying out from the inside, first, as far as where those initial roots have reached. Always make sure when you irrigtae it goes all the way down to bottom of substrate, even when watering tiny plants in a large pot. it's good to start with a smaller column up top... it'll spread wider no matter what you do by the time ti gets to the bottom, but better than the alternative. start in a smaller pot. it's just easier. Ensure they are easy to remove from said smaller pot -- i.e. hard plastic is less ideal than a soft plastic you can push the plug right out and not disturbe it at all.. preserving rootball. This avoids transplant shock 99% of the time. I'm not sure i've even see transplant shock, yet, over a couple hundred of them.. albeit a small sample size.
