Dark period before flower

I'm doing a side by side comparison where I prepped my plants for flower then gave most of them 36 hours of darkness to speed up the flowering process. One plant was left in the veg room during this period and will be moved over when the lights go on in the flower room. Lets see who gets flowering pistils first. Will update soon!

I give mine 60 hours of darkness at the start of flower, never done a test but I think it speeds flower.

Lol because time is money, this hobby is fun to try new things with, if it works why not do it, missing one day of lighting to answer a question won't hurt yields that much, at least I'm not rushing harvest time! I can't speak for everybody else but I wanted to try it so I tried it.

i feel like you should have put one in 12/12 while the others are in complete darkness as well. Just for even more fun

Agreed! That would have been nice. As it is I'm just counting days until I see pistils. I didn't technically plan on doing this experiment it was kind of a game time decision as I was prepping for the flip like oh yeah I always wondered if this made a difference, lets try it out and see...I seem to try new things with every run. Some I have liked, some I haven't!

That's a long time. May I ask why you chose 60?

.

Dr Greenthumb advertises his flowering time after a 48 hour dark period.

I follow that and add another 12 hours to fit my garden's timing.

Lights go out in veg at 9 pm and on at 9 am, that's 12 hours, then two more days of darkness for 60 hours.

The extra dark time is suppose to speed transition into flower, it seems to be working OK.

Alot will have to do with how mature the plant is prior to sending to flower or a "dark period".....let's say you have 2 plants from seed both germinated on the same day. You wait 4 weeks to send one to flower and 6 weeks for the other plant for flower. The plant that is sent to flower at 4 weeks will not flower unless it's mature enough to do so. No different then starting a seed at 12/12 from the start. It just stays smaller and will not flower until the plant grows mature enough.

Most my girls are usually mature by 4 weeks. And the 4 week plant will have grown more under 18/6 than under 12/12

I was using it as an example....so the dark before flower thing will have a major deciding factor in how old the plant was prior to heading into a dark period.

Yea i suppose. I do a LOT of training so sexual maturity is never an issue. My girls have typically been bent over backwards dozens of times before they get to flower.

The plant that was left in veg for extra days longer is likely going to take longer to transition to flower. If you flipped one/some to 12/12 and the rest went into darkness that would be a clearer test of what you are trying.

I’ve never seen anything bad come from the dark period before flowering. In theory it might help it transition a day or 2 faster, but it’s not some major breakthrough development that is going to have a huge benefit to the plant either. I’ve done tests with dark vs no dark and it was never any significant differences. Typically I grew with mature clones though so they would transition in 5-7 days anyway and then begin to flower either way.

And then they'll be rushing to harvest early posting pictures of a plant covered in white pistils. Is it ready? Should I chop now? I see some amber. The breeder time states 8 weeks and I'm at 8 weeks and 3 days. Fast forward a month from harvest: Why does my weed smell and taste like hay?

Hay is for horses lol
