Is it heat or lumens that stress the plant?

My signature link "Trying Uncle Bens topping technique" is an accidental log of the two plants in the first picture. The plant on the left is the "Uncle Bens".

Here's the plant in question...photo taken about a month ago:

This is my first sativa.....is there an average chronological age I should expect?

If memory serves me correct a Dalat Vietnamese was vegged for my usual 4 weeks and then put in at 12/12 for like 4 months or so before it showed flowers. It took something like a total of 7-8 months from start to finish. Your mileage may vary. I have read that equatorial sativas grown in such places as the Yucatan and Colombia can take up to 14 months from germ to harvest. Phytochrome just doesn't seem to drive these types unlike today's mutts. Definately not auto flowerers which have Rudy in them.

While I have your ear...this is a dumb question: When a breeder list flowering time, does the clock start ticking at the first sign of budding, or when it goes into 12/12?

The breeder's listed flowering time for this strain is 10 weeks....will I have to wait 10 weeks after the first sign of budding? That will suck.

When a breeder lists flowering time, he's fudging and telling his target group what they want to hear. Everyone wants it right now, so they up the time, plus how plant grows and when it finishes is mainly driven by the grower's culture mainly temps (genetics aside).

14 MONTHS!?!?! I'm not getting any warm and fuzzy feelings with that prospect.

I've grown offerings from Dinafem before and went back to them because I've gotten big healthy plants from them with a 100% germ rate. They also are pretty close to guessing flower time compared to what I experienced.

This apparently has changed my opinion.....at least with this strain. I'll give this plant more time until I need the space, and if it turns into a marathon plant, I may have to chop it down.

I'm sorry I have hijacked this thread this past 24 hours, and hope it gets back on track. Thank all of you for your input.

Oh.....back to hijacking this thread...

TO UB:

if this plant is more about chronological than photo.......If I took some clones from it, would the clones recognize its age, or would the clock reset? In other words, would the clone flower faster in 12/12 than the mother? I have a clone of this and am wondering if I should toss that too if the mother doesn't co-operate.

Man I'm sorry but that's just ridiculous man.. I only grow landraces and been doing so for a good while, most of mine flower 16-24 weeks. I grow south/central American sativas and therein lies most of my experience. No south/central American sativa flowers a year. I've heard of perpetually flowering plants years old.. and that's insane but true, so are sat's that grow like vines cascading along the ground. But to say a plant takes a year and a half or whatever is ridiculous.... also saying that its flowering is age or whatever based is just as absurd, i wouldn't be able to grow 12/12 from seed or veg a plant 9months then flower, which I have done.. I don't know much about any other kind of weed but I would have to assume on the opposite side of the world their weed acts the same, considering it adapted in the same photoperiod conditions..remember even at the equator on the equinox day and night isn't equal 12 hrs. And none of these plants originated exactly at the equator anyway

My problem is that I've set myself up to have 8-9 week flower cycles and about the same in veg cycles so every other month I have a harvest. I made the mistake of adding a few sativa's into the mix and obviously they are throwing off my master-plan....by a bunch.

I have White Widow and Mataro Blue (indicas) sharing the flower room and have more indica's warming up in the bull-pen that are probably 5 weeks away from needing to go into 12/12. So at some point in the near future, I'm going to be backed-up if these sativa's don't start budding now.

Man crush? Kinda like how you follow Uncle Ben around this forum every day parroting everything he says? lol

Came expecting 5 pages of discussion. Drop your egos at the doors fools. jesus
