Bringing three week old girls outside

I have a bunch of 2-3 week old girls I need to bring outside. I know I need to harden them for an hour then two hrs, then three hours, for a few days prior to transplant.


They have been under 24/7 light for three weeks. I can reduce the light by 1.5 hrs a night for three to four nights, but how closely do I need to match the amount of time they will recieve outside without them going into flower this soon?

If I drop down to within 3-5 hrs will it be okay? I guess Im wondering if I move them from 18 hrs inside to 14 hrs outside will this trigger then to flower?

Or at this age is it okay to just put outside without messing with the lighting time because they are only 3 weeks old?

It wont trigger flowring tell the light hits 12/12.

You do not need to worry about switching the lighting because your plants are under the 2 month mark.

At around 2 months seedlings become Sexually mature and then you would have a problem. But before then you are good to go. Your plants being only 3 weeks old are premature seedlings in a young veg state.

Its safe to toss them right outside without any worry of early flowering.


If you had clones you would want to run them for 2 months on 16/8 lighting before they go outside.
