Hey WP WHAT'S UP ? I emailed Nirvana Seeds and asked them what timeframe they used to estimate the maturity/harvest of their strains. This has been a frequently asked question on here, so I went to the horses mouth . I'd like to say thanks to Walter for the quick response! Here is what he said .
When the first pistils are visible you start to count.
that's pre flower.........if you start counting there and stop when they suggest I would be harvesting too early...I say "I"cause everybody's setup is a lil different...I posted a pic I think and showed what I call day 1 of flower...
@ ChAs ... Do you know if all or most other breeders use this same time frame ? I always thought it started at the flip to 12/12. We need to have a standard, universal, conscientious for all breeders !!! @ Rick...You right on about "everybody's setup is a lil different." I don't pay much attention to suggested time frames, but I did want to know how Nirvana did it.
My last grow was 5 different strains from all Dank seeds. I started counting the day i saw flower for each unique strain and my timeframe was spot on.
OPINION: It doesnt matter what kid of setup you have or what lights as long as you stay 12/12 and you count from first sight of flower you should be very close to the breeders time. The timeframe is genetics
I always just check the trichs. Get a pocket microscope and base it on how the trichromes look. I harvest sativa strains while the trichs are still milky and haven't turned amber yet. I let my indicas go all the way and when I can spot check a plant and most the trichs I see are amber I know it's good to chop.
