When Does Flowering Start??

Hey wats up i was wondering how do you find out when your plants are going to start flowering

i went to www.sunrisesunset.com but im not sure if the time has to go down to 12:00 hours or what?

if so then my flowering wont start until September 27th??? i thought it was supposed to be mid august?

i live in so cali

Outdoor they start flowering as the days shorten. Some strains are more photoperiod sensitive and are already flowering, some take longer. It will start soon .

well my days started getting shorter last month why arent my plants flowering yet?

Nature will take its course. I have some that are flowering and some that arent. So far so good!

well i have MOAB and im supposed to use it on the first two weeks and last two weeks of flowering
so how am i supposed to know when to use itt?

they'll all be flowering at (or before) mid august

How will i know when to use my MOAB ??

Ronny,

Go look up what your latitude you are at. Then go look up sunrise sunset times for that latitude. When days get to about 12 hours long, then you will see flowering beginning within the next two weeks.

so this is when flowering starts in my area?

September 27th 2011

Sunrise: 6:40am
Sunset: 6:41pm
New Moon: 3:10am
Day length: 12h 0m

Well, you can add an hour for dawn and dusk. So, probably a month or so before that.

K

so does this look about right?

August 29th 2011

Sunrise: 6:21am
Sunset: 7:20pm
Day length: 13h 0m

Yes sometime in mid august it will start to turn and a little while after that you will notice bunches of hairs. (hopefully)

alright cool thanks for the help

Everything will start long before the 12/12 date. Mine is the 26th of Sept(damn military time screwed me up). That's when plants and pretty much everything finishes,

Should add the 12/12 date doesn't take into account twilight.

i live in san diego and already have preflowers on all my plants....cut back on nitrogen and hit them hard with p + k....i gave mine super phosphate 0-45-0 and potassium sulfate 0-0-50 1/4 cup per plant... mine are about 6.5 feet tall so if yours are smaller than cut back...thats basically the same as the shooting powder you are going to use....give it time and frequent watering....you should show flowers by august....this is the simplest way to make any plant start to flower right now......bought my ferts by the pound for about 1.50 a pound at my local garden store...call around...watermelon kush...G-13...white russian are the strains ive done that on this year...all plants are outdoors in directly in the ground...look at my profile pic

It depends on where you live. I live in the pretty much the northern most part of the us and I get a ton of sun in the late summer. Even september 1st Im clocking about 14.5 hours of visible light a day. I have to keep the girls in a greenhouse at the end to let them finish naturally. If you are in a dense field of vegetation, (i.e. forest) night comes much faster than what the internet says for the "length of day".

I have a qrazy train from seed that just started to flower its in full sun all day. I have 1 other qrazy train that isn't flowering yet and 4 Deep purple plants all in full sun started as seeds in may and none of them are flowering yet.

I'm getting 14 hrs even some flowering some not 12/12 is indoor controls nothing todo with outdoor plant will flower with as much as 16 hrs of light go ahead hit me but be ready.
