I’ve got 4 Skywalkers and 3 Gelatos that went from 20/4 to 12/12 on January 12th. They were 65 days old. Skywalkers, 56" high. Gelato’s, 48 inches high. They are now in full flowering stage. Question: I’m wanting to put them outside now cause weather temps allow it. But light is sunrise to sunset is now 11 hrs. Will they know the difference? I need to put them out to make room for 13 plants from the starter room that are 1 month behind the above. Those will go from 1500W grow/flower light at 20/4 and then go outside at Equinox. They will think it is Fall, but really Spring… 
I’ve got Gold Leaf to start and need the start room. I’m not real concerned but thinking there are some experts out there that can assist. I grew up on a farm and have a degree in Ag. We grew tobacco growing up and these “Weeds” are a piece of cake…
Mr. Bergman… I thank you…
Uh, they’re autos. They don’t care. So long as your environment is good for them; put em out!
If you are talking about the Gold Leaf; being a photo it is sensitive to ambient light. The rule is 14 hours of daylight and at least 8 hours of direct sun. There should be an almanac for your area.
Will autos reach 4 1/2 ft tall?
Oh, yeah! Depending on pot size and strain.

Thanks. They were going out anyway but you’re right. The “Girls” won’t know the difference.
I think you are fine in your location. It’s good you asked though! Make sure we get to see some bud porn.
21 days of 12/12 after 70 days of 20/4. Just starting to pop.

Bobbydigital: guess I’m stretching it as I’m measuring from bottom of pot (roots). They be 56” Skywalker ‘s or 48” of measuring just plant. Sent pics.
