Leaves on seedling sticking straight up indicate anything? Is there such thing as too much light for a seedling? I have a timber 400w vero fixture (right now only operating at 40% power) @ 36” above canopy. Environmentals are good 77* 70% humid.

Yea you can definitely stress a seedling with too much light. It’s early days but that seedling looks perfectly fine to me. You running MH or HPS?

400w timber 3500k cob fixture @40% on the potentiometer. I’ve recently turned it up slightly

It looks fine dude just keep a close eye. If it starts stretching too much just lower the light a tad. Better to be on the safe side until you’ve got the hang of light distances when starting out. Would rather stretch them a little than cremate them lol

Agree with smokey I’ve never needed a humidity dome for seedlings. If the coco gets dry just water them.

Seedlings don't need humidity domes. At least not the ones I grow.

Agree... I can keep my grow spaces consistently at 75-80% rh if needed so I’m not sure a dome would add... I am trying rapid rooters and jiffy pellets this go round—and I’ve never used a propogator—but I’m trying one out right now.
