Do T5s produce tight, PHAT buds? Several of my girls have forearm size colas (liter btls used for visual) Here's a tease shot taken yesterday. ~ 3 weeks to go. More in my journal

I've had colas the size of my hand from T5's but they definitely ended up being airy. Could have been strain. I am growing same strain now in my HPS room to see. My T5 grows are on hold for awhile because I need some heavy yields. .4gpw wasn't cutting it.

^^^^^^^your welcome^^^^^^^

knew it would come in handy some day, I don't tend to throw away much anymore. As you can see the Fiji Purple is a really great bulb. I have been using it in my T5 setup for months and haven't switched it out for obvious reasons. I keep 4 of them in my fixture during veg and flower and have had nothing but positive results. I use 4 Fiji Purple bulbs, 2 UVL Red Sun, and 2 UVL Super Actinic for flower and I think I get better results than under any HID! Puts out a real nice magenta color between them all.

U Mind CLEARING THAT UP A BIT?? AS IN THE POSITION WHERE THE BULBS ARE ON UR FIXTURE FOR I HAVE 2 8 BULB BB FIXTURES TONS OF BULBS BUT DONT HAVE A CLUE HOW TO ASSEMBLE THEM CORRECTLY FOR THE SPECTRUM.

I would like to get to the bottom of this fact or fiction wavelength debate. Has anyone done any real testing with 420nm vs. 460nm to see which is more beneficial or not necessary? I've heard mixed messages when it comes to this debate. It doesn't seem like there is a clear answer. Lately, I've heard that 420nm is the preferred wavelength.

I do know that the Hortilux Blue MH lamp has to be the best lamp out there for growing. I've only seen great results growing with the Horti Blue. I do know that the lamp contains much lower blue wavelengths down into the 400nm region so could this be the answer? I do know that this lamp has more 420nm than 460nm. It seems the 460nm may be of less importance than the violet wavelengths, 400-420nm. With this being said, I would like to see some side by side comparison between using 460nm and not using 460nm. Has anyone tried combining lamps only using the UVL super actinic for the blue light? Anyone tried mixing only UVL super actinic and UVL red suns yet? Results? I only want tried and true proof, not opinions. The web is full of opinions and not so much actual fact, so please do not quote some science webpage or opinion from someone else because all that matter is facts, tried and true experimentation with photos, etc.
thanks for your input

I was able to find the answers to my own questions for all that are interested. For the last week I've done a side by side with actinic vs 460 and what I found was that without 460nm plants do not do very well and growth slows. Without 420nm you do not get the photo-response as much but seems to be of less importance.

I did a side by side using only ATI aquablue specials and 660nm in one panel (2/4 and 2/4) and in the other panel I used nothing but Giesemann Actinic Plus and 660nm (2/4 and 2/4). The results were quite comparable. But when I switched to using UVL Super Actinics and 660nm without any 460nm wavelength, growth stopped and the leaves quit "reaching" for the light. The FloraSuns have ample 460nm in them as well and I have started a new panel with Flora suns at 2/4, an Actinic plus at 1/4 and a 660nm at 1/4. The overall light color is more red due to the added red in the FloraSuns so it may be a little more suited for flowering. I would really like to find a good mixture of light that does not have a need to be switched when flipped to 12/12. Does IR really have an effect on the budding process? Has anyone done any side by sides with and without the IR? It can't be as important as the other light bands it seems like.

That's some excellent 411. I am ~ 3 weeks from harvest. Yesterday I replaced a UVL Aquasun with an ATI Aquablue Special pos 1/8 (though it probably needs to be closer to 4 or 5.

IR

Go to ledgrow.eu. Hans did a test with pics. Bottom line he included IR diodes, but IR is best provided separately on a separate timer to be on for ~ 30 minutes following main lights out.

If you keep the bulbs 8-12" above the canopy the light will disperse over a broad area

I've just finished reading through your thread, I must say it has been a fascinating read. I keep an aquarium myself and it never occurred to me about using those lights.

I'd like to say thank you for your research, I'm going to try your methods on my next grow.

FYI DO NOT USE 3 coral waves per 8 bulb. Way too much infrared!!!! I had an extra one laying around when my redsun went out. Used the coral wave for a temporary substitute and had 2 already in. Most of the fan leaves got a little toasty....

I guess I'm not seeing where he talks about the benefit of IR. I see that he says the deepred 660nm was preferred over the cherryred 740nm, but I don't see where he says what the IR addition does to the plants. Could you please link me?

No IR's on his panel..........it's 4 (hans calls them "far red") lumiled diodes 660nm deep red......the rest are cree xp-e 630/460nm........his omission of uv/ir was due to cost/inefficiency of the current led tech.......

So does anyone actually use them? If so what are the results? With a DIY aircooled hood I don't even understand the reason why anyone wouldn't go this route if they actually work well.

I personally have not/ used CMH bulbs for my grows(plenty of IR).......but there are a couple people who run them at ICM@G....and ask petflora on how many hours a day to cycle it(on/off).........good luck
