Dark period before flower?

I have heard evidence of i beleive a dark period before going into flower. Something like 24 or 48? I am coming up on 12 hours dark before i put the hps in.

I would not mind waiting this out if gives me more and better bud. hehe. I am finally at the stage of discovering patience for the plants. After all a blub change on a sealed hood and a res change are not all that fun after work. Forget it's friday, the girls need me.

So 6 weeks veg and they coming up on 12 hours dark. They were under 24/0 for the last few week of their veg. Should i give them another 12 the go.

I foget where i read this dark period is beneficial.

ty for your responsesl.

i put mine in the dark for about 36 hours before flower.

supposedly it resets the plants internal clock and helps the transition from flower.

they get a really long night so start to think that they need to bud, then the 12/12 comes and they know they need to bud... i have found it takes a couple days off of the total time, and i start to see flowers earlier.. i wouldnt say it adds onto the yield tho

+1, 24 hours dark then 12/12 is what I do... Lets them really know it's time for flowering.

I noticed a little faster setting by week 2, no real yield increase.

Based upon experience, I too can vouch for the effectiveness of 24 hours of continuous darkness before 12/12.

That's a sick avitar, you got almost no rep... Here's some for ya.

How about that, I gave you your second bar...

aww man dont i have a cool avatar? its home made LOL

Yeah, that's a nice stadium, but it's not animated... Or shall I say claymated?

Spreading the +rep

thanks guys. Sadly I was talking with this other guy and he told me that nah, just to flower. I checked he had a lotta informative looking posts.

But I did give them a 8 hour flower period first, they about to go lights on now for their first full 12 hour day. So they got a short day, their first time out. I wanted to keeep the flowering to the night for heats sake.

Ty, reps, congrats on the second bar.

lol, thanks!

I figured it was time for a new one and this made me chuckle

Stoners, easily amused

That's how Adult Swim stays in buisness...

I just switch the bulbs shortly after the MH cools. I dont know about any 24 hr dark period before flowering....shit they will be in flowering for a few months so what does a short dark period do several months earlier?

It's more of a direct shock that tells them to start flowering, 24 hours darkness, then 12/12. I also cut back to 10/14 in the final week.

on this grow i did 24 hours of darkness then 12/12. today is the 7th day of 12/12 and they both have hairs

i went straight to 12.12 and had pistils the next day.. but my plants were very mature.

hey mr howard.... im taking ur tips on my upcoming harvest and was wandering as well after the 10/14 for the last week do u leave it 0/24 for 2 days straight before the chop? or just chop em after the last week. =) thanks!

I just chop them down when they're ready, no darkness on the last day. The shorter cycle should be enough to squeeze out a little more resin.

thanks +rep please feel free to come visit my grow and comment... first time around, so all help needed. pics in a few hours when the sis comes over with the camera =) 29th day flower today.... lookin beautiful as ever!

i do 18 6 veg 24 hrs straight for the last week of veg then 24 hrs of darkness then 12 12 for 6 weeks then i go down 15 mins a day till the end

if i want to finish in 6 weeks for any reason i give 48 hr darkness 3 times thru the 6 week cycle
