Looks good
Irish. Keeping those lights at 10/14 for now is the right idea. Once you're done with these, you could try 12/12 and a far-red (IR) light source (LED=best, otherwise 'black light' incandescents like dogs is using are fine if you want to go cheap; one can always run 'em through a
Rosco Dichroic IR Filter also to assist with the removal of non-IR from the bulb) on your next run. Just set up the IR to come on ~15min before normal 'lights out', and run it for ~15-30min afterwards, then shut it off. This will 'remind' the plants it's time to flower - i.e. you're giving a slight assist to the natural
Dark Reversion process that occurs at night:
Should kick the
Phytochrome Pr---->Pfr equilibrium back over to the left side of the equation enough so that flowering starts. You may get a bit of mild stretching (more than 'normal' for the strain) from that during the first ~3wks of flowering, but not too bad (plants are most susceptible to stretching from IR in the early morning hours (~4-9am), not just after dark). You'll more than make up for it in the increased lighting duration.
(Adding Far Red (IR) in the
absence of visible light will cause a certain % of the Pfr to change state back to the Pr form more quickly, so you can reduce the total time in darkness).

We'll probably find that Sativa-dominant plants have a different level of sensitivity to changes in Phytochrome, and different levels of equilibrium states reached, than Indica-dominant plants do, once proper university-sanctioned lighting studies are done on mj in the future.
I liked the
coco filters you mentioned, though you can definitely DIY something cheaper. Lots of sources for
Activated Coconut Charcoal Online.
Coco's great stuff - we can grow in it, kill odors with it, and it's a 100% biodegradable and a renewable product, too. Can't ask for anything more!
Hey
ganja, good to see you mate. Interested to see your updates on the 532.8nm-treated seedlings with new pics, whether they've been burned or not. Put 'em up!
Cheers,
