Today I was told by the collective I got my clones from that you should go dark for 36 hours between making the switch from Veg 18/6 to Flower 12/12. Has anyone else heard of this? This is my first time growing, my girls are very healthy and I don't want to mess this up. The dude said let the light go off at the usual time the last day of 18/6, dark for 36 hours straight than make the switch to 12/12

Can stun them and cause herms.
Never heard of this but not perfered.
If your going to waste a day and a half just go down on your schedual slowly.
16/8
15/9
14/10
13/11
12/12..

No stunning and is more natural.

I think everyone has heard of this, but if you do no know the specifics of what your growing then just stay on the tried and true path of flipping them to 12/12 and stay away from fables.

If you have never heard of this then why say that it could stunt them and make them herm? I do this EVERY time and have not had any herm problems (knock on wood). This is done to set them into flower immediately where your schedule would gradually set them into flower. And you are only losing ONE lighting period, the other two would have been dark anyways. Edit : I don't think this lighting schedule would be to blamed for hermies anyways

You gotta push the envelop if you must grow indoors.

Anyways, try harvesting after 72 hr or 96hrs of darkness. 36hrs doesn't do anything.

I've read where you let them sit in the dark for 72 hours after BLOOM, before cutting/drying/curing. But I cannot see the logic in them sitting in the dark BEFORE Bloom. We do the switch to emulate nature and get the plant to bloom, there is no blackout that long in nature. So I wouldn't do that. As a matter of fact, I just did what was suggested above with the gradual change from 18/6 to 12/12 over 3 days. My first 12/12 day will be tomorrow.

its almost as if people HAVE to try things just because they haven't been done before.
If that wasn't the normal order of things there would be a lot of things that we do now, that we wouldn't do. It's difficult to say how much would be different from growing to living to jumping off cliffs, but I am wiling to say that all in all, experimentation is a good thing.

If you are emulating nature, tell me where you live that you get 18hrs light and 6hrs dark? Where is your logic behind that?

LMAO........Everyone has heard this but noone knows for sure....And the same thing with leaving them in the dark for 2-3 days after harvest to get more THC, come on folks....

gets dark after 10 about 10:30 - 10:45 and the sun comes back up around 2:15 am
like 3 1/2 hours of dark in our longest days.

um where i live dude. north America.
And I suppose your sunlight goes from 18/6 to 12/12 over the course of three days like his too huh? Think you are missing the point. He was saying that he is emulating nature but in the same sentence saying how he went from 18/6 to 12/12 in 3 days. You may get 16 hrs of light a day where you live, but that is by no means the norm and I gaurantee you the guy who posted that is not your neighbor

Yea in nature u probably get 14 to 16 hours of light where u live. But u also get moon light. And as a result flowering takes forever. If it were nature it would be outside. 18/6 works great because u give the plant more light than nature so it can collect more light energy to grow and u r still giving it a dark period which I believe is healthy for the plant. Difference is the dark period is actually dark. That being said, just switch it to 12/12 and let it ride. Too many people get in a hurry. Just make sure ur dark period is all dark. Light leaks r what make hermies. Letting it sit 36 hours in the dark is a waste of time and probably hurts more than helps. Plants need light to grow and MAKE BUDS.

Someone really should do an experiment with 10 plants of the same strain, light etc. and have 5 in the blackout and 5 just switched to 12/12 to see which plants show signs of buds first and put this issue to rest. I would bet that the black out plants get the flowing signal faster but it's just a theory and I have no data to back it up.
