Pretty sure this would be something in that individual plant's genetics. Some just decide they want to show their sex earlier, usually an indica trait no? We've always used dark periods before going into normal 12/12 to force flowering when a plant is at about the size we want it to be. IE: 2-3 days of darkness, doing this you miss out on a bit of that first light explosion of growth but it's a trade off. To each their own, I prefer letting them sex out by themselves but it helps in a clinch with grows in a tight space. GL~

Thanks man, unfortunatly i thought i could do 24 hrs dark before flower, but i'm in my 8th week of vegg on my first four, and got four more two weeks behind them, and so on!
Had to rush the 6 week old ones to flower at the same time, but oh well! I'm running out of space!!!LOL!!!

I missed the dar period but 2 days later i had sex signs female on 2 girls and 2 males i think forming. I vegged 5-6 weeks, and the buds are nicely beginning.

I wish i coulda had the drak period i was willing. Some one told me no. Lol.

I put my plant in darkness for 24 hours before i start 12/12.

Flower earlier mang, you don't have to grow monsters to get great yield. Your indicas will usually get about 40% taller when you switch them to 12/12 but sativas will double or triple in height. Just keep that in mind when you're planning space. GL with your beautiful kids

thanks man, i can still drop the buckets down about 2 feet if i move the makebelieve table i made for them. I plan on dropping them when they expand in flower.

I was looking for a way to speed up flowering a bit. I am on week 6 of flower now and think I will give them 48 dark once a week till I cut.

Thanks for the idea.

Oh, I veg 18/6 and 24/7 doesn't seem to make a difference. Haven't tried the 24 dark before 12/12 but makes sense. I will give it a go.

dont do it once a week, youll get herms lol

That's what I was about to say, if you just shorten the light cycle to 10 on 14 off, I find a bit better of a finish, I only do it in the last week though... Don't turn the lights of 48 hours during flower, that's no good at all.

So then from what I am reading this is a totally safe thing to do? I'm thinking about doing it when I leave town over the holidays and doing a 32 hour dark out, cool?

Yeah, it's safe. Don't do something silly like feed it too much before you go cold turkey though, I had a friend who did that this time and stunted it's growth really bad.

Okay, so just a normal feed right before I leave I should be okay. I was worried about not being able to water them after my 3rd day out of town, but I think a dark out period will help out. I found that 1000 watts hps over 2 gallon pots of soil needs a lot of attention.

Yep you should be fine, just do a good water before you go and it should be okay since you don't have lights bearing down on it.

Stongly agree with the dark period. If the light goes off monday night at midnight they wouldn't come back on til Wednesday in the AM. I get immediate results in regards to "the switch".

thanks for the idea man, i know i've read that multiple times now. I'm on my last week and need my big girl to finally finish already!

btw, i did the 36hr dark period and it worked like a charm on one of my bubblegums but didn't do shit for the other one. Little female showed 2 days into 12/12 and the big girl showed 12 days in and its also taking a GOOD week, week and a half longer to harvest, same strain.

Nice I have turbo and awd too!

I drive Subaru, you too? Or Mitsu?


I don't see that big a difference with the dark period before... But they'll finish out better if you cut 2 hours off the lights and raise them a bit, a little extra frost.

yeah mines currently down and out, been that way for 8 months! fuckin mitsubishi. It's actually a 91 tsi awd. I also have another one my brother bought that came on a flat bed and hasn't moved an inch since last year. haha 95 GST eclipse. Fun cars when they actually run. Mine ran 12.52 @ 110mph last year and was a fucking blast to drive.

I'll have to start cutting the lights off 2hrs early, I just bought a 60-100x scope, chopped a bud leaf, looked at it under the microscope, couldn't believe my eyes, first time i've seen amber trich's so up close, i didn't think my plant had any. man was i wrong. this girl is ready to chop after flushing, and it still has 90 percent white pistils 2in from the top.
