LED Without LEDs -My First T5 Grow

AltarNation said:
I am hoping it works! The only ways to work around the big 4-foot fixture I've come up with up til now was to either a) rig up some sort of "christmas light like" diy string of LEDs and run them amongst the T5 bulbs under the structure...

I like this idea. With the correct LED driver you pretty much could make a christmas light like string array with 20 or so 5 watt 660nm LEDs inbetween your T5 bulbs and just glue the LEDs right onto the fixture. Might want to consider those individual LED heat sinks or a fan blowing on your light fixture. I'm not sure you would be able to cool your fixture enough. I know LEDs require adequate cooling to even work properly.
 
Will this bulb give us the far red we need?

heh just added a reptiglo UVb 10.0 (26w CFL) to my afore-outlined setup, sitting between the 2xCFLs on the bottom of the diagram, and down from the UFO, so basically the footprint with the UFO gets more UVb dose (no UV in the UFO) but at canopy height, slightly above the other CFLs as I am trying to splay the output across all of the canopy.
Some of the tops are as close as 8", most more like 15-20"...after 2 hours no significant damage visible so I may leave it on for full 12/12 if it doesn't show negative side effects.
 
Ive looked at those also, they're a 610nm bulb, good for commercial displays and games at the carnival, not so good for plants. Sylvania does make the Gro-Lux which is a tri-band tube heavy in 630-660nm like other pink plant bulbs, but with a little less green I think, I also think they're EU only.
Ive googled every combination of T5 and Red and seen so many bulbs (and found quite a few that use the same SPD that everyone thought was the Fiji Purples for so long)
 
I retract my former dis-approval for the Roseate's, I think they may have their place in filling in a complete spectrum. They appeared flat white next to the FloraSun and RedSuns but on their own they do infact show a pink/rosy hue. So there's some red in there, but Im still reserving them for the topmost slot in my sidelights. I got my replacement PlantGrow's so they've replaced the Roseate's in my main flowering panel. The PlantGrow's are almost identical to the FloraSun's, but twice the price and I think lower quality... I had one snap in shipping, then the two I have now both have small nicks on the inside of the tube, maybe where the mercury has scraped the phosphor off the glass, or where it just didnt ahere properly, but there are areas that have tiny bright white specks on the otherwise rosy tube... not good. tiny UVc leaks.

Pics later. Final version of my flowering panel. Harvested Mari-guaro Cactus! 14.60oz wet wt.... for 14" total height!!!! granted wet weight, but 1oz per inch of height lol!
 
The calyx's never seem to fill up as much as they should when I grow. Is there something that can be done to get the calyx's to swell more?

I felt the same way towards what I thought was the end of my grow... but the parts I left to mature farther eventually swelled and I definitely see the difference now. My problem was that my plants tended to keep foxtailing and growing out rather than swelling... I think this was a symptom of heat stress though. Also, while the calyxes did swell, I also feel that it over-matured a little, so I guess I missed the window on both harvests.
 
Well, I just started straight H2O watering, do you think that this is a good time to start H2O only, or should I keep givin em something to eat? And what should I fed them at this point?

I'm feeling that they don't need any more food from here on out(unless someone says otherwise), but is there any other sort of non-nutrient type of additive or booster that would be good to mix into the water, or STRAIGHT PH'D RO WATER ONLY? I've always kinda been unsure at this point what to be giving them as far as the liquid type goes. Some people say to use a sugar type based booster(Molasses, Honey, Sugar Cane Vanasse) through the whole grow up until the last week when you start to flush with plain H2O, but I've always thought the sugar boosters were for the veg to flower stage and more for growing, not the ripening stage. Does anyone have any experience with these types of carb boosters? Or recommend another type of ripening sauce?

Top Down... FloraSun, RedSun, CoralWave, PlantGrow, FloraSun, RedSun, CoralWave, PlantGrow

Here's what the roseates look like next to different bulbs

bloom, actinic, x2 Roseates.
They look good here, but arent as pink as FloraSuns or PlantGrows. My side panels will be (top down) Roseate, RedSun, Actinic, Bloom

Are you sure these will grow cannabis? Looks like they are growing lettuce from the manufactures photos and using them as supplemental lighting to extend the photoperiod for strawberries, not using them as the main source of light. I can't even find where it gives the wattage for those single bulb $68 LEDs. The strip versions that sell for $250 only use around 30w. I purchased a 36w Kessil for $195 with free shipping. Sounds like another expensive, low wattage supplement alternative.

Here are the specs for the 4 ft strip 660nm only LEDs that sell for $234 a piece, they are only 28w each. That's like spending $234 for one 4 ft T5 tube,
