it might be a 3000k i can barely read the label let me get back to you on that. you think this okay for veg? been working good so far(3days) these are old bulbs that came with the light but they light up so i figured may as well use them

no worries dude, I just like to help. I would have guessed it was a 3000k if you hadn't said it was a 5000k earlier. I think it would work for veg, wouldnt be optimal but would work, would prob give very short internode distances, but would be slow growing...it wouldnt kill em :)

im cool with slow growth and short internodes got time on my hands, so its cool, plenty of clones.

He's talking about the AquaticLife Roseate 650nm

View attachment 2107132

Its a good bulb, but the amt of green and yellow in it makes it look much more white than the FloraSuns or AquaMedic PlantGrows I have. On its own, it looks a little pinkish but next to the others its a flat stone white. Not a bad bulb for the $, but FloraSuns are even less at $8. (I realize it may sound like I work for ZooMed, Im just reeeallly cheap and they're good quality for the $... AquaMedics are $22ea and dont seem to be as well made)
Id pass on that bulb. I'd get the Ushio 3000ks over that all day

cool seems pretty good for some half assed old free bulbs. better than my Mh imo. now that all about this t5. here soon im gonna be pairing t5 with hps or LED seems like this is the best way to get the sunlight indoors. this t5 shit is pretty sweet i must say i did not know there was this much to flouro, my next goal is to get some of these CL and start over driving air cooling and blending spectrums

Why are you using kelvin as your scale. I'm targeting certain PAR. I trying to accomplish a near perfect blend of par and get as close to the different peaks of chlorophyll a and b as possible With still having g/y/o in there to help with photosynthesis.

par lighting is certain wavelengths of light. So 650nm seems pretty close to 660nm and having it be a dominant wavelength. Ie exactly at 650nm instead of a "blend" Seems better to me.

I know that you have said you prefer the generic cheapo grow/bloom bulbs before, but I dont know why. The only SPD I could find for the Ushio 3000k bulb is this one

I thought this graph looked odd for a fluoro because it was lacking the usual mercury spike at 420, but when I went to save it I saw it was actually named "HPS 2100k". this graph seems to lack much true red anyway and is primarily yellow/orange... I think I'd still take the Roseate's over this SPD if this was actually the 3000k Ushio's... Im led to think that the Ushio's would be no different than the previous two graphs I posted for 3000k bulbs. If they had any true red over 630nm, they'd appear more pinkish than orange and may even have a higher kelvin temp like the FloraSuns which are 5000k or the PlantGrows which I belive are actually rated at 6500k. (again showing that the Kelvin temps are only a generic label to give a lamp, PlantGrows are just as pink as FloraSuns and dont appear blue at all, although they're given the same 6500k rating as the common bluish 6500k grow/veg bulb... and those 6500k grow bulbs actually appear green as fuck in my PAR flowering closet, where they're the heaviest in green of all my bulbs.

Woot! Just popped a tap root out of a seed that is at least 8 years old. Now let's hope it's female. haha

That was exactly where I found that BS graph that is actually for a 2100k HPS. The other two links are for product pages where they are obviously marketed as commercial lighting, ie under cabinet and high-bay, where human eyesight would be the goal... so I still say that they are gonna be the opposite of PAR lighting, dominant in green/yellow/orange and little blue or red

I use the wave point bulbs, and do OK.
Hay Alter, I ordered the colasas, and killing fields. I am glad you got your order. I am still waiting.

Shit... I might have to chop early again... they are hardening up but I still see so much new growth... the thing is, I'm seeing really bright green splotches in the new growth... and they've got me thinking hermie... :( Is it normal for new growth in buds to show up bright green? Whatever they are it's so small I can't tell... looks like pistils coming out of most of them... but I'm not too sure overall.

They really look good too... I'm going to post up a new thread with pics, maybe you guys can chime in on what you think... I'll link it in a few...

Fresh growth brah! When mine go through a good flowering spurt I notice some of the fresh flowers and calyxes are really light green/yellowish before they mature a bit in the light. I get the hermie jitters sometimes too, but with my good genetics at least, I haven't had a single nanner yet
