Switching to flower 12/12

When i switch my plants over to 12/12 what should i do bethor this should i give them a feed of plaing water and switch the lights out for 48hrs?

NO!
Where did you get that idea from?
Just reduce your lights to 12 on/ 12 off.
And reduce any Rhizotonic you may have been adding to their feed.

If you're going to add any PK13/14 or bud booster type supplements
you don't add it for the first 4 or 5 weeks of flower.

Where you from?
I'm guessing your first language isn't English.

I got it from forums which i have seen on here so was just making sure.
And im using advanced nutrients not canna so im using like big bud and overdrive just going to feed how it says on the bottle?

If there's an A N equivalent to RHIZ - reduce it.
It's a waste once flowering starts.

I don't use A N.

Apparently switching your lights off for 24 hours or maybe even 36 before the switch helps shock them into flower modes. Gives em a little poke in the butt :P
I woudnt go 48 tho

My grow philosophy is keep it simple, keep it gentle. I don't want to shock my plants into anything when I know nature will take its course. Just figure out when you want lights out to start (6pm, 8pm, 9am, whatever) and then just start. I have lights out 6pm to 6am, so when I decide to flip, that night I just turn off the lights.

my flower light schedule is 8am on - 8pm off....i regularly keep the lights off for 36 hours when switching to flower (i.e. off 8pm Monday - on 8am Wednesday). the idea behind this is that it supposedly increases flowering hormone production, giving your plants a little boost going into flower. as for watering, if they need water then sure, water them...definitely don't give them any flower nutes yet though
 
Hi Dale. Most everyone here is right in one way or another, and really, we're all just showing our different growing personalities. Our plants our like mirrors into our souls.....seriously tho....only the BEST genetics outperform the limitations we put on them as growers. Know what I mean? Most of us are pretty broke and have a hard enough time getting our lives together, let alone put extra time and effort into something else (which usually appears to be growing fine anyway). I like the idea of having a definite way for the plants to tell it's time to flower. Most people simply use the normal, average lighting schedules to guide their grow cycles (18/6 - 12/12). I personally use the 'nudge' method that's been discussed in this conversation as well (you could argue that these 'nudge' methods are more of a shock than a nudge). For me, because my electric bill won't go up no matter what, I keep my veg room lit 24hrs a day....all day erry day. Then, when you move them into the flower room it's super easy for them to tell. I've found that almost ANY strain will begin flowering at exactly the one-week mark, almost every single time. Of course, then, I use a 4ft 4bulb T5 flourescent for veg......and in the flower room I have a 1000w & a 600w. So, the difference in lumen intensity is a little drastic....which probably also helps them notice a difference. I would rather opt for the more subtle difference, like nature. Pretty sure very few, if any, of their ancestors ever experienced 48 hours of straight darkness. The genetics might not know how to handle it! ;) Naw, it might even be an interesting way to alter common genetics wayyy down the line. I agree with kryptonite, "keep it simple, keep it gentle." Answer rockogtr......and then start flowering the shit out of those little bitches.

Absolutely
If there's nothing comparable in nature
It's not happening in my grow room.

I understand that indoor growing replicates natures most effective aspects
(often making it quite far removed from actual nature)
but it's only to a matter of degree.

To my knowledge there is nothing in nature that would subject a half grown plant to 1 or 2 days of ZERO SUNSHINE.

I had lights out from 10.30am to 4.30pm during Veg
first day of Flower flip lights went out at 8.30am and came back on at 8.30pm.
These were the warmest 12 hours so needed less additional dark cycle heat.
 
just want to comment about the 'if it doesn't happen in nature then i don't do it in my tent' sentiment. plants don't care whether something happens in 'nature' or not, all they care about is optimal conditions. this works out because 'nature' happens to provide very good growing conditions for plants, but the most important thing to remember is that these conditions can always be improved upon. so yes while it may be true that plants never experience more than 12 hours of darkness in nature, this doesn't mean that 12 hours of darkness is the optimal condition. all putting the plants in darkness does is decrease the transition time from veg to flower. it doesn't speed up flowering times or increase flower quality or yield.

sciencey words - under normal conditions flowering is influenced by 3 factors: sexual maturity, photoperiod, and temperature. an outdoor plant naturally flips to flower because its phytochromes detect less hours of daylight and the plant detects a decrease in temperature, which in turn increase gibberellin (GA) production, to essentially induce various cells to switch to flower mode. this happens gradually because temperatures and photoperiod decrease gradually in an outdoor setting. now, all we are doing by putting plants under 24-48hrs of darkness is trick the plant into thinking it's dying by way of lack of light inhibiting the majority of photosynthesis, which induces these hormones, inc. GA, to be produced to try and quickly get the plant into flower as fast as possible so it can be pollinated and reproduce. so again, while a typical plant may take up to a week to 'flip' into flower under normal 12/12 conditions, putting a plant under darkness for the first day tends to reduce the time needed to 'flip' to only a day or two.

cheers.

"all putting the plants in darkness does is decrease the transition time from veg to flower. it doesn't speed up flowering times or increase flower quality or yield."
Wouldn't decreasing the transitional time decrease the overall flowering time?
