Plant worrying me.

I have a seedling about 5 days old. The plant grew very fast and is at the top of the ag greenhouse dome. I removed the dome this morning and after an hour the plant's leaves turned upward (pic included). Has anyone else encountered this ? Im a noob to this ( first grow ) so any help or suggestions would be much appreciated. Thanks.

You should definitely put your plant labels on before your plants get too big.

Ya, first put the labels back on because the light will cause mold to grow on the sponges ... destroying your plants. Also the leaves may be curling upwards because they are reaching for the light .... make sure the light is really close to the plants ... 2" - 4"

Check out my grow in my signature .... has everything from day 1 to now ( week 2 of flowering)
