That wasn't the case for me. I kept the bulbs as close as possible >2" off the canopy.Anybody thinks this might be a factor in what we're hearing lately?

Possibly, I've always have mine 12 inches away for the purpose of spectrum blend. I have not had any issues.I wonder if any of the divergent results that are being reported have to do with light height.
The type of combination that okthanks 2 is talking about has bulbs with more complete spectrums, as opposed to the aquarium mixes that have some narrow spectrum bulbs. I believe we've concluded that with the aquarium bulbs its better to keep the lights a bit higher than usual to allow the spectrums to blend. Putting narrow-spectrum bulbs close to the canopy should result in poor growth. Similar issues have come up in the LED community in terms of distance to canopy and spectrum mixing. Putting your LEDs too close doesn't work well.
How high off the canopy have you been putting your lights okthanks2 and RedOctober?

Been keeping the lights 14" from the canopy.I wonder if any of the divergent results that are being reported have to do with light height.

Been keeping the lights 14" from the canopy. NOTICE: READ HERE: NOTICE: READ HERE: NOTICE: READ HERE: So if you miss this post it is not my problem anymore! LMFAONEXT:Just checked in after running the comparison between T5 combinations after 2 days. (as a reminder to those that don't read good: LOLIn room #1. 8 bulb fixture with 4 of the 6500K $2 bulbs, 2 Redsuns, 2 ATI Procolor.In room #2. 8 bulb fixture with 4 of the ATI procolor, 2 Redsuns, 1 ATI blue plus, 1 UVL Super actinic. AND NO 6500K BULBS! YAY!BOTH ROOMS ARE ON 24 HOUR LIGHT CYCLE. TEMP 75 F, RH 50%Room #1 is growing like crazy compared to room #2. Height from canopy is the same. Same everything else. Gonna give it another 8 days as promised and report back (with photos for those of you that don't know how to use the search feature.) Room #2 is still having stunted growth issues after round 3 of this same trial. I'm seeing some new growth so I would say that it is safe to give it more time and see if there is a change. Compared to room #1, however, it has it beat like a rusty bent nail.HYPOTHESIS:This test will show that the addition of 6500K bulbs will have better results than the addition of the blue plus and super actinic bulbs.NOTE:For all the people in here that have been bad mouthing me for using 6500K bulbs, when you finally see that the $2 bulbs work better than the $17 dollar blue or actinic bulbs, are you still going to be bad mouthing me? I really STILL don't get it. I'm trying to find a cheaper way to do this by getting rid of useless bulbs and keeping the ones that actually are doing the job and still use the RED specific bulbs. Ultimately we all want fast, vigorous healthy growth with a high yield and low heat/energy consumption right? Or do the people that have a problem with the 6500K bulbs only want to use expensive pretty color bulbs in their grow and not worry about anything else? God forbid that a 6500K bulb is in the mix, since they pretty much represent the same color of the sun on a cloudy day.
Mine have been fairly close ~2-4 inches or so. I swapped out the Super Actinic for a Flora Sun. So now I have 3 Flora Suns and 1 Coral Sun. I was getting that twisted/deformed leaf phenomenon which could be from the lights being too close or it could be a nutrient issue. The water temps have gotten rather high into the 70's which may be causing some nutrient deficiencies and slowing growth as well. The T5 does raise the temps in the room into the 80's and I don't have any real good way of cooling it, so the plants sometimes have to negotiate high rez temps.I wonder if any of the divergent results that are being reported have to do with light height.

I do believe this is a false statement. Got any evidence or research to back this up? Not trying to be a smart ass or anything, just genuinely interested.24 hour lighting screws up the photo period if they dont get any dark.
Do they sell those 6500K's @ Petco or Home Depot? Or would I have to order them online?RedOctober, the reason growth has stopped is because these bulbs do not work for some strains. Seems as though some strains prefer the RED over any blue at all. Try the 2 Flora Suns and 2 6500K for a week and see what happens, I'm sure you will be shitless with surprise. red causes stretching, blue causes tight internodes
Yes, between posts 2009 and 2010 you posted about 8 times where you insulted myself, prof and hyroot mixed with other generally negative comments. This is why in post 2013 Hyroot comments on you calling others teenagers... and you continue still, calling others dickturds and liars when everyone else knows otherwise... can we please stopDeleted posts? What? Dick turd #2. Enough with the lies. Please don't respond to anymore of my posts. You pretty much only come in at the end of someone else's insult to add more insults. That is very adolescent behavior. I really don't care how old you are, but please do not talk to me or about me anymore. Anyone else have any other crap to say? Keep it to yourself.
I've tried about 5 different types of daylight bulbs. They are all pretty close in comparison as far as color goes, but some lack lifespan. So far I've found the Zoo Med Ultra Suns to do a fairly good job but they are quite spendy(about $11). The spectralux's are what came in my Sunblaze and they have worked extremely well for the past year. It is about time to switch them out for new ones though. I am also pretty sure that home depot's T5's are NOT high output. Maybe it's different at the store near you, but here at least they are only normal output T5's. I have done some researching for some other cheaper resources for 6500K bulbs and have found a brand called Plusrite. They are about $2 a bulb if you get them in quantity. I have read reviews that they are pretty descent but haven't tried them yet. Any 6500K will do as long as it doesn't shit out on you early. Keep in mind here that the bulbs that are REALLY doing the most are the PINK bulbs. (FloraSuns, plant grow, floramax, gro-lux, plant and aquarium, procolor, aqua-glo etc.) I wouldn't be surprised if that is all you need for a good harvest. But the only reason I add the 6500K is for vegging for the added blue and green. To try and keep the plants shorter.Do they sell those 6500K's @ Petco or Home Depot?

Do they have to be Spectralux? Because think Home Depot has some 6500K T5's (could be 5000K though), but I have no idea what the brand is or the spectrum. I would assume that like every other bulb, not all 6500's are created equal.
I know I've already asked you, but what bulbs are you using for veg and how many of each? Also, what type of strain are you running? What nutes? Everything is still looking awesome as before. I'm sure if I was still running the NL strain I wouldn't be having any problem whatsoever, since that strain will grow anywhere. The last strains I've been working with are BB and OG and they have been proven to be REAL biatches. I have NEVER seen a plant that refuses to grow under 6500K lights alone. The OG has been about 4 times harder to grow than the BB, but it is sooooo worth every minute. I have read that a lot of people don't have much luck with the OG and only get small flowers (although high quality). I'm actually starting to understand the OG now and get what it wants. Pretty much you can NEVER say NO to OG or you will be ignored for a long time. LOVES being foliar fed, LOVES the Mg, LOVES the RED light, HATES being dry, HATES eating more than necessary, absolutely LOVES the 24 hour light cycle and HATES excessive blue light(seems strange but this strain would NOT grow under a hortilux blue 400w MH no matter how much I begged it to and no matter how little or much it ate!).That wasn't the case for me. I kept the bulbs as close as possible >2" off the canopy.
You're absolutely right, the Home Depot ones aren't HO; I didn't even think about that. I was hoping that I could at least order them from an aquarium store if not buy em locally. I won't order anything from a grow store personally. I could get the Ultra Suns @ Petco though if they are the same as the 6500's. I'm just looking at the two graphs of the Ultra Sun and the spectralux and they look fairly similar. Also you had posted the graph for the GE 6500K on page 145 which looks basically the same as the Ultra Sun. So I guess any one of these would do? Petco is probably the easiest to buy from so I guess the Ultra Sun will be my version of the 6500K. I like that you are doing side by side experiments, and even though intuitively the 6500's red peak is not optimal (610nm), there may be some property about it that creates a synergy with the other bulbs in veg to create growth. I'm going to give it a try. I will start with 2 Flora Suns and 2 Ultra Suns alternating, and maybe bump it up to 3 and 3 if it works.I've tried about 5 different types of daylight bulbs.

I've read in MANY reviews that the GE starcoat 6500K bulbs don't last very long. I would try for the Plusrite 6500K brand. They will have the number 865 in the model #. If you can find a bulb with 965 in the model # that would be even better, I'm pretty sure the CRI rating is higher on those.You're absolutely right, the Home Depot ones aren't HO; I didn't even think about that.

I am pretty happy with my flower combo of 3 Flora Suns, 2 Coral Waves, 3 Red Suns, but if a 6500K would help there too, I'd swap out a Coral Wave or a Flora Sun. Have you noticed the 6500K having any effect on flower, or just veg?
IDK, send him a PM, he will respond to you.I'm sure this has been asked a billion times but how do you get your pics to appear in the post "in line" instead of as attachments like UnderCurrent does?
I read it in dj shorts book, Growing Acceptionable Cannibis. When I get back home in 2 days. I can site it. Im out of town for work. I'll try see if I can find it online.I do believe this is a false statement. Got any evidence or research to back this up? Not trying to be a smart ass or anything, just genuinely interested.
