Question about Flowering / Light

dannyboy44 · Mar 14, 2014

So I know basics. in a photoperiod plant go 24/0 or 18/6 than switch to 12/12 indoor to induce flowering.

I have searched for the answer to the following question but cannot find any good info.

Question as follows;

Say I start seeds indoors and give them either 18 or 24 hours of light for 6 weeks or so. Now i want to induce flowering. Can i plant outside in late April or early May and get flowering from the approximate 12 hours of daylight during May-July

Reason i ask is I'm doing a sativa, Durban Poison and would like to grow outside and harvest in say May or June.

I have searched on this strain and eveytthing i read says harvest in Oct/Nov ?

A bit confusing to me. i'd think that 10 weeks of flowering be it in May or Sept should't matter. is it possible that the days are just too long during the summer to induce flowering. Indoors you do 12/12 and outdoor in the summer mother nature does 12/12 so why do my sources say to harvest in Oct or Nov?

You can't adjust nature's clock. If you want to grow outdoor you gotta play by mother nature's rules.

haha thats my kind of question. seems as if too logical of thinking will get you into trouble in tho field. i guess technically only 1 day would be the same then the the few minutes of change would be on the wrong side.

Yes days are getting longer but not longer than the 18/6 or 24/0 veg indoors.

At an equinox (equal length of day/night), days are at the shortest length and the nights at their longest length. At a solstice, the days are at the longest length and the nights at their shortest length.

After an equinox, days start getting longer and nights shorter. After a solstice, days start getting shorter and nights longer.

You start outdoor crops after an equinox, they grow through the solstice, and start to flower on the approach of the next following equinox.

You can induce flowering in the summer outside. It is a pain in the ass,but it can be done. What they do is cover the plant in a light proof black plastic at 12 hours of light. Would suck to do that every day but some folks do it. They harvest the buds in middle to late summer let the plant re-veg and then mother nature will take over for the 2nd flower cycle. I guess if you didn't have too many plants and they were close by it wouldn't be too bad.

Yes. I know the solstice is the longest day but as I mentioned NOT longer than an 18 or 24 hour veg so will it work ??

Cannabis flowers solely due to how long the dark period/night is (day length doesn't really matter) per 24 hour period. Cannabis needs approximately 12 hours of darkness for flowering hormones to build up to a point of having the plant produce flowers. 9 hours of darkness isn't going to result in flowering.
