There's a process you want to follow called 'hardening-off' which is always used by tomato growers to reduce shock.
When plants are first set outdoors, it is into a sheltered location, ideally a cold frame, and it is left open only during the warm part of the day for the first week or 2. This lets the plants get used to the cold night air gradually.
Another thing that cannabis growers need to consider is photoperiod stress. Try to keep your plants on the same schedule of light/dark every day. If you cannot guarantee a good schedule, keep a light- even a single CFL- on them all the time just to maintain a 24/0 schedule.
stinkyattic Reviewed by stinkyattic on . question I have about 10 plants in seperate pots. They are inside for now, and all of them are sitting near a window that gets pretty good sunlight. Can they go straight outside, since I've been letting them get sunlight or do I still need to put them outside for a few hours a day first to let them adjust to direct sunlight? Rating: 5
