Hey guys I have a question I'm hoping to get some insight on. I have a couple light dep greenhouses that are a a few weeks from being finished. I'd like to stop pulling tarps before they're completed so I can cut down on moisture related issues, but I'm a little uncertain about when its safe to do so. I have a house that is 2 weeks from being completed, and another that is 3 weeks out. I'm in the middle of the Willamette Valley. Any advice would be greatly appreciated!
When is it safe to stop pulling tarps in Oregon?

If you match your photoperiod it won't matter. Sunny or cloudy days don't make a difference in photoperiod either. Light protons are light protons, strong or weak. Problems occur when the original nighttime hours fall out of sequence with light deprivation hours. Match your hours and you will be good.

Nice! What are you growing? The cultivar surely plays a part in this, seeing as some start flowering earlier than others (i.e. when days are still longer).

Ok so Indica-ish hybrids and you stopped the light dep when days were about 14 hours long. Sounds very sensible. Thanks for sharing your experience!
