All i have to add to this long post is green and other light is there so you can see your plants... and make sure there the right colors

Grave mistakes can be made overlooking the involvement in genetics and UVb response mechanisms. Choose mountain strains for best results imho.

Hawaii has 4 times more UVb than the mainland. This goes for all tropical zones including the non-mountainous ones. I don't think you need to have a "mountain strain" in order to make good use of UVb. I know what you are saying though. I am willing to bet that all cannabis strains benefit from having UVb added to the noon-time hours for short increments to simulate direct sunlight and to stimulate the production of THC and the highly valued and important and over looked terpenes. Yes, a plant on a mountain will be exposed to UVb in greater quantities (especially on a mountain in the tropics) but it also would have a higher intensity in all other wavelengths as well, not just UVb.
canopy under T5 mixture with CFL 65w plant grow lighting on the side,
here is the color analysis with the added red sun in place of the plant grow T5 along with the additional side lighting with the 65w plant grow,
photo of the canopy with T5 lights off,
are there missing pictures here?

i cropped all the images together so it could be seen without having to scroll down a whole page, the side lighting is under the T5 mixture. it's just one plant that's had the bonsai treatment if that's what Youre wondering??????LOL
I noticed some strange new growth and i'm not sure what to do about it. It was like the new growth was growing with holes or tears in the leaves. They've stopped reaching as much for the light fixture. I took out the red suns and put the ultra suns back in so now its back to 50/50 ultra/flora plus 1 fiji purple. It would be nice if someone would take a close up of their canopy with NATURAL LIGHT to compare. I keep going back and forth liking and then not liking the red sun bulb, I'm not noticing if it's helping or hurting, all I know is the growth perks up again after switching them back out for the ultras................hmmmmmmm, what to do what to do, so far I haven't been really seeing anyone on here say the red suns have been beneficial or if it's not red enough and then some people actually say the bulb is crap

I only say mountain strains because that is what I and others have tested. Many sativa doms that have been bred for the last 30 years under HPS have shown adverse reactions to UVb levels easily tolerated by Kush/afghanica strains. My personal opinion, take it or leave it. I know tropical strains/hybrids (don't forget those tropical strains can have mountain genes from decades/centuries-old seed trading---a great human tradition) that do great, and many academic studies have correlated UVb balanced sun emulation to increase terpenoid precursors which result in increased volatiles production (it just straight up smells better). I can easily smell out medicine grown with blue light vs not. And honestly where you find blue you often find the UVs, I know we hear UVa is useless but until rigorous study has been performed, let us just assume that the PAR/PUR graph doesn't just plummet after the magical 400nm threshold is crossed (chlorophyl absorption, in my eyes, continues at reasonable rates into the UVa range---rates that seem comparable in the CO2 tests to 500-600nm aka yellow/green "high penetration" <--this because of the leaf reflectivity phenomenon amply discussed in previous posts by yours truly. I also submit that as a photon of 400-500 nm wavelengths carry more energy/unit than their 500+ counterparts = ignoring morphology stuff just for a moment pls thnks. If the UVa is also high PUR light, then it should be even higher energy than the blues, possibly to a point that it would more quickly overwhelm the photosynthetic electron transport systems. Not trying to rant just to sound smart, I'm just trying to explain why I like that UV t5 so much. If all that 280-400 is useful to the plants, at a reasonable distance to avoid oversaturation, this could be a great development.
Not saying this means anything but as per this map:
It would seem to me that Hawaii isn't that far off from much of the Kush mountains with regards to UV index, it would be an elevation thing from there. I'm with you on the tropical strains producing terpenoids to deal with the UV, as above the hybridization may also result in them overproducing glands like the mountain ones probably HAVE TO DO. But yea a lot of the terps have UV protective capacities too. The main function I see however is the insect/fungus/microbe repelling properties they have. That would seem so much more important in the tropics where humidity, bugs, and bacteria are just waiting to have their share.
Anyhow, I've always like that the coral market bulbs have little UV spikes, thanks for the flora sun tip btw, I got some coming to see if I can correlate a morphological change like you reported.
I'm done ranting for tonight, all the best,

Prior to this change, the CW was abutted by 2 Red Suns, so even though they look red, they aren't providing the same red nms as the FS, which looks bright white. Odd, but true. This morning tons more trich production and bud swelling. Ima get me another FS today!

I think the benefit of Red Suns (or not) has to do with how much blue coverage you have. I went with 2 ATI Aqua Blue Specials + 2 Red Suns = pseudo Fiji + 2 CWs (later removed one CW), but probably did not have enough red (or too much blue), so adding the FS kicked up bud production, so will get another FS and replace one of the ATI ABS.

What bulbs are you using for flower? Have you found any particular optimal bulb mixture?

I went to 3 stores in search of another FloroSun today, but no luck. Local stores- petco/smart/supermarket all have pathetic bulb inventory. One place called All Fish Emporium had a variety of bulbs, but no zoomeds.
I did pick up a 50 watt uvb reptile bulb to add to in one corner of my seedlings/clones closet, which is; 2 x 2 x 5, fully lined with ref Mylar. Sockets in 4 corners midway up/down for side/underside cfl lighting + my 2+ yo UFO 90 hanging from the top. Damn uvb cfl was $18. Got it on a separate timer, along with the other 3 cfl side light bulbs @ 4 hrs per day (12-4) . The UFO will stay on 24/0. Could be interesting.
Just moved one Monster Cropping Clone from the closet to my T5 rig, where it will be growing in an HPA (high pressure aero) pod. It's pretty cutting edge. I am excited to see what the 2 will do in tandem. I have one of my X seedlings in there now (female Sat dom + Indica male). It is growing like a mofo. Alas, it is a male, but have several others getting ready to move in.

aquamedic,
why not just use these?
it really seems like a person should be able to get away with using actinic/plant grow in a 25/75 ratio. like 6 plant grows and 2 actinics, or Fiji purple instead of actinic.

How about 6 flora suns(or plant grows) and 2 coral wave? Seems like it would work.............has all the peaks right???????
How about 4 flora suns and 4 coral waves in a 50/50 mixture,
I'm gonna leave the 50/50 flora, coral in there for a few days to see what happens. I know a few people have reported that the corals initiate flower response because of the small IR peak in them? I wouldn't be surprised if ALL actinic bulbs have this IR peak as well. I don't know, seems like a lot of blue

So after waiting a month and a half for more suretogrow my hopes of cloning went down the tubes, I had to start with new genetics from seed.
Here's 3 weeks under 216w
1x 454nm
1x Super Actinic 420nm
2x Redsuns
P.s I just started to flip every other day from the outside 4 tubes 420+, 454, & Redsuns.... to the inside 4 tubes 454, 75.25, Fiji & 420+... to give more spectrum, In my opinion they're still to small to receive all 432w.
