@Trae1170 I practice and experiment with some of this, and have been doing so for years…
In fact, you’re just catching me making seeds and revegging some of my plants. I wasn’t counting on this working, given these had been pollinated late and the outdoor was really rough.
I was able to bring plants inside a few weeks back so they could finish up seeds. I threw them in a little veg tent usually reserved for lots of small plants and kept the lights at 18/6. Revegging this way can be a very long road back, but if you have the right plants it can happen fairly quickly. I had the right genetics, but plant health when bringing them in was questionable.
One of these is a BBM x Vintage Blueberry that I just harvested F3 seeds from that was placed outdoors in the worst of conditions early in the season. It actually saw a dip below freezing at the beginning and end of its time outside (April-Nov). After less than a month indoors, it’s about to take off again in full reveg mode, all while finishing up seeds in the last. It has been in a tiny 1 quart pot it shared with her brother since April.
The larger of the two was the runt of all my keepers of Sour Diesel x SSH BX1 F3. I sent it outdoors with a bunch of other castoffs and it became one of two shinning stars of my outdoor. She’s very haze forward, but you get fuel and diesel on the back end with a hint of bubblegum sweetness. What she isn’t great at is flowering quickly. Tough to say for sure since she was pollinated young, but I suspect a more haze like bud structure and 11-12 weeks of flower once I give her a full go.
Excuse how crazy this all looks, but it’s a weird mélange of cuttings, plants from seed, that was all improvised to get these seeds to the end after them being in terrible outdoor conditions. The fact that I’ll get cuts and a second round of flower and seeds is a nice bonus since most outdoor plants didn’t survive to even come inside.
My experience over the years is that added photo period length and/or nutes doesn’t seem to speed up seeds finishing faster in a significant manner.
That said, I have experienced autos under 24 hour lighting and excellent conditions finish seeds remarkably fast. Like viable seeds in 3-4 weeks fast.
