I've got a mother plant growing indoors. But my setup is far from optimal, so on nice days I move the plant outdoors, where it seems much happier (then if she is left inside all day). But on days where she goes out, she then really sufferings in the evening. The cycle goes like this. At lights on in the morning, she looks pretty good. (Not great, but good.)



Then after spending the day outside, she comes in (around 4-5) and is looking real good.



But starts heading south. Within 4 hours shes's drooping and starting to claw up.



By lights out (16 - 18 hours) she's really suffering.



By the next morning she's looking good again and if I move her out, goes through the same cycle. If I just leave her inside all day, she does OK (but never looks as good as a day in the sun). I'm not doing anything different between in and out i.e. No watering, fertilizing before or after the move, nor do the temps (65-75) or rh (~50) fluctuate much between the indoor space and outdoors and has decent airflow. I've got a junky little plurble light, which isn't very good for vegging, but does the trick during the 2 months I need to grow indoors before I clone her (and move everything outside for the summer).

She had to stay fully inside for the last 3-4 days (with cooler/raining temps) and looking OK.



So my question is does anyone have any ideas on why the plant droops so bad after doing an outdoor/indoor move? I would think if it was just the light, then the plant would always look like shit if left inside all day. (I'm wondering if it could be a respiration issue where it takes in moisture outdoors, but then can't get rid of that much water indoors?)
