Flowering outdoor plants with 14-15 hours of light?

[Noonin NorCal]

Hello all i was wondering since my plants are stretching so much and its up towards the fence line if i gave them straight flowering nutes like Maxsea Bloom 3-20-20 if that would help them flip over to flower? They are not in pots they are in the ground and they are G.S.C. I dont have the right material also to black them out to 12 hours i sure wish i did

Or something lighter i have some liquid Kool Bloom 0-10-10?

Marijuana is photoperiod sensitive. Only 12 hours of pure, uninterupted darkness will make them flower.
Doesnt matter what you give them?!?! Nutrients wont make them flower.

Depends on the genetics you use. The critical photo period is different for each strain. Some start flowering with just 9hrs of darkness. Equatorial sativa strains are either daylight neutral or start flowering only if darkness is more than 13-14hrs.

Use Them Danish strains for example.

14 hours of dark at the equator? nope.. have to be at +/- 30 degrees from equator to reach 14 hours of anything. Also, i hate Maxsea, i think it`s trash. I dont like urea in my plants, i dont piss on them either. Not enough magnesium in Maxsea, is says "organic based" but it uses chemical concentrated salts. yuck..

advice.. Bend your stems down without breaking them. it`s called trained them.

If that was true equatorial sativas would never flower. I think it's pretty widely accepted that pure sativas like that flower based on plant age/temperature/etc. Would be interesting to see how much daylight you could get an equatorial sativa to flower with. If they are truly daylight neutral shouldn't you be able to get one to flower with 18 hours of light eventually?

If you want to grow sativas, like the pure ones, they can keep on going in the veg stage for over a year sometimes. If you want to flower these indoor, you must switch to something like 11/13 -10/14 to get them to finish and to keep them from overgrowing your garden. When outdoors, I recommend giving them less Nitrogen then usual and make sure you darken them after a few weeks in veg. When I'm talking sativa or 'pure' sativa, i'm NOT talking about a 12-14 week strain, but more in line of 20-26 weeks flowering.

Hope it clears up some misunderstanding.

so pure sativa's are daylight neutral (meaning daylight in their natural habitat isn't a factor to start flowering ). That doesn't mean however that you cant force them in to flower by giving them 14hrs of darkness (instead of the usual 12!) in our climates. (that's why they flower very late when outdoors). Doesn't happen in nature (equator). Some strains will flower in february, others in september.. depends on the location and genetics.



sorry for the off-topicness

Interesting point. Could be possible, however, that'll be almost like an autoflower gene that has to be in there somewhere. But I really don't think you'll get an equatorial sativa to flower at 18hrs; not according to my experience.

Daylight neutral isn't the same as being autoflower. but then again... bit off topic. We should have an interesting discussion about this. I remember a few scientific studies that have been done in this area... I'll try to dig them up!
