Nova OG Auto planted Oct 8, 2022. Harvested Jan 4, 2023, week 13 seeds in ground. Ninety one days from seed popping to harvest.
The other two plants in the Auto Tent are a couple or three weeks behind the Nova OG.
There are maybe several things I've learned from this grow (I need to wait until the plant dries and the rest of the crops are in before I'm close to certain they are true). First is I believe a couple of hours of UV-B during the last few weeks before harvest will increase your Trichromes. You can see how "frostie" the buds on this plant are. Second and on this one I could easily be full of it, I'm thinking to get full growth you need "full spectrum" LEDs or at least different lights than the ones I'm using. I've had my high end* Blue/Red LED grow lights for a couple of crops and on each the size of the plants disappointed, tending towards the low end of expected height and production. Bud weight was good for size of the plant and the buds are tight but... Third I've worked out a water/feed schedule that works and last, within reason, bigger pots do not make bigger plants. My current thinking is 3 gal fabric pots for Auto-period plants and 5 gal pots for Photo-periods.
I've several Auto plants outside the Photo Tent with very cheap "full spectrum" LED lights that are impressive. When this grow season is finished and stats are in, the Blue/Red LED panels may move to the greenhouse to supplement the full spectrum Winter Sun.

Oh boy, where do I start. Yes, you are on to something regarding your lights. Since legalization, more and more scientific research and studies are coming out and shedding light (pun) on how light affect plant. Turns out, the only thing the plant care about is what promote photosynthesis, the engine of growth. Only important specs in grow lites are the Photosynthesis Active Radiation, from which we can derive PPFD and map it. Bottom line how many photons of the right frequency are hitting the plants per seconds is what matter. That would dictate the distance from the source to the canopy, which varies greatly between types of fixtures and technology and how used. Bottom line very hard to make apples to apples comparisons between grow lite. Full spectrum is (or was until recently) 400-700 nanometers, but now they realized that IR and UV also play a part in plant development, so you need a " different" full spectrum and its frequency response would ne nice or you cannot really compared, and effectively we are comparing with sunlite (the original), so we need to model (filter) our frequency response to mimic it, not flat across spectrum. etc etc. Looking into the science behind grow lite is a deep dive :-)

Here is one year worth of footage time lapse from start to finish. Watch how the plants react to lite. That is why it is better to ramp up/down versus simply on/off. Less stress on plants
