Flowering 4 weeks indoor then 4 weeks outdoor

[tba77]

Hello.
I have 2 plants ready to follower. the thing is that 4 weeks from now I`ll be away for 3 weeks and while Im gone I dont want to leave my closet on. so I have 2 options:
1. start flowering indoor 4 weeks and then move the plant out for the remaining time.
2. take them out while im away, and begin flowering when im back.

what do think?
Thanks.

I recently faced a similiar decision. I should have cut my plants back and flowered after I returned.

You can, with a bit of effort, calculate the day length for whenever you'll be out- if it's shorter than 14 hours it should work- 4 weeks in, 4 out. Just a matter of timing!
