Im always following along here so if/when you notice anything worth mentioning i hope to post it for me to see.
Just a gut feeling, but i suspect getting these lights down to 12" will be very difficult with just about any strain. That might be optimum but, theyre just so intense.
If you have the NL laying around you should run it when you have the space. Theres a reason the NL has stuck around for so long and for why its used to cross so much. It is a very very hardy plant, quick finisher, aromatic, heavy yielder and a hard hitter. Its hard to find a strain that doesnt have a bitbof the NL in the lineage somewhere.
Love it...
Yeah I try to remember to post any changes or observations, good for my own reference - lol
12" above canopy would be too low imo for a couple of reasons. Even if they didn't burn/bleach the plants, your coverage would be questionable unless you had a lot of light over them. With single panels in particular, that low would likely provide little coverage on the edges of the canopy and reduce your overall yields. Even with my multiple Tasty bars, spreading them out too much had a noticeable effect last round, decent yield but extended finish times, very noticeable on the end of the room that had less light running.
This round I'm running them a couple of inches closer, 16-18" (not a huge change, I was 18-20" last round). I'm also running a smaller footprint with the 100w bars spaced closer together, so my coverage per sq. ft. is closer to 30w and more evenly spread across the footprint. As mentioned last round there was a notable difference in finish times on the end of the room with the lowest w/sq. ft coverage (22w), pretty sure that was the only variable as I had one pheno on both ends of the room and there was at least a week difference in finish times between the two. I believe this will be the main factor affecting finish times.
The other change though this round was going to 12/12 from 12.5/11.5. I'm running many of the same phenos from clone so I should see if there's any noticeable difference in yield. My main goal is to see if I can reduce the overall finish times a bit and maintain yields running 12/12.
So far, no notable effects and plants seem to be maturing at normal rates:
