Droopy marijuana leaves

A question from a fellow grower:

im not 100÷ what strain it is but I am planning on putting them outside for the summer, basicly the problem is when my plant is under lights its fine and looks beautifull but when I take it out in the sun after about half an hour the leaves start drooping and the top section of the plant bends over, any info or advice would be a great help

Are you watering them when you put them outside? Drooping can be caused; Ironically; by over watering; Or, under watering.
