How to force outdoor plants into bloom?

Force Flowering

Force Flowering

Evening peeps'. I have heard of a few growers doing Force Flowering.

I have wanted to do this for some time, but am rather limited to space. Mainly due to the fact that my garden is not that big enough to place another shed (as i already have 2). But i have done some growing in the shed (soil,coco,htdro and dwc), as well as generally growing MJ in pots outdoor.

The other day i bumped into a fella who not only has just got the green finger bug, but started force flowering back in june (so no doubt he will be cropping in 3 or 4 weeks time).

The generall sensus from my neck of the woods is if you have a shed, that's ideal for the 12hr dark period. But a few peeps' have mentioned just throwing a large heavy-duty black bin liner over the plants.

If you can construct a small frame, wrapped in white/black/white, that would be very ideal as it can me made bespoke to your needs.

Interesting point
(Although on a different matter)

Also from test's i'v done in the past regarding light regime (indoors), was increasing the light after flowering has been initiated. 3 1/2 - 4 weeks into 12/12 incerease the light period by 10-15 minutes every other day, so that by week 6 the light is 14 1/2 - 15 hours on, 9 1/2 - 9 hours off(respectively).

I was on 15/9 for 1 week. With 2 weeks to harvest on a 60 day strain. Then decreased light by 10 minutes each day. It prolonged flowering by a week but increased yeild slightly and potentcy was big.

My point is (as freezer boy stated) "most strains will flower with less than 12 hours of darkness". But 12 hours of uninterupted dark will be eccential in the first 3 weeks of bloom to induce flowering. Once an Indica (mainly a 100% Indica) plant is locked in flowering it won't stop. Where as a Sativa will reveg if light were to increase from 12 hours (hence why it's suggested to decrease light from 12/12 to 10/14 (or even 8/16) in the last 2/3 weeks of bloom).

The conclusion is That when the light decreases the plant know's autumn is on it's way and it needs to reproduce (like us all!).

yeah but i feel safer locking them up i dont live in the nicest area. last year my plant got robbed and sometimes cops run through my yard chasing somebody and i dont want them to stumble upon it.

Ah, that's different if the shed's doing double-duty hiding your plants. And you only have around five weeks to go, so hey!

Yep, that's what I did last year, and it worked perfectly. Thing is, you don't even need to go to the trouble of constructing a frame--a forcing structure does not have to be perfectly light-proof to be effective. This year I'm using a tent that allows in filtered light, and it's working just as well. Cost only $65 and took just a few minutes to put up. It was a revelation that the structure doesn't have to be pitch-black! Best $65 I ever spent.

I am new to growin and have never grown outdoors and just started two clones.BUT.....How and When do plants flower outdoors? I thought you needed 12 12 for flower but what do you do outdoors?
I wrote a in length thread about Cannabis blooming, it is in the sticky section at the top of the outdoor forum, look for the one talking about Photoperiod, all your answers will be there.

some of you new users are just straight clowns (or lazy), try the search function bro (its your friend, dont be scared)...

guys like Backcountry are what make this site great, going around answering the same questions over and over from new users...

on the force flowering note it seems lke backcountry's first post (page 1) outlined everything pretty well..

Deps are good but dont expect huge yields, they wont grow like there full term sisters...
