If there is a large difference in the envrionment between the indoor and outdoor, that will shock the plant unless its a gradual change.

For instance, seedling/clones that have been grown indoors under weak floros and then suddenly set outside in full sunlight are gonna be seriously shocked and likely die. Normally, temps in full sun are higher, that might also shock them to death.

I really dont think its a good idea to change the envrionment in a drastic way, and there is no indoor lighting, no matter how big/strong that comes anywhere near the lumen output for full sunlight. It seems like an indoor plant would enjoy a sunbath, like we humans enjoy it, but if you are going from indoor lighting to outdoor light its best to do it gradually. Start with an hour in the morning, then 2hrs in mid morning, then 3hrs in the afternoon, then 5hrs mid afternoon, then maybe a half day on a cloudy day, then a full cloudy day, etc. Work them into it slowly for best results. good luck
