lmao maybe, just showing whats possible. Merry xmas dude

mine have been showing sex around 7-10 days of 12/12. It wont be hard to see as long as you know what to look for. Google image search male cannabis flower and female cannabis flower to get lots of examples. but so far everyone here has been right, too early to tell for now, but you'll be...

make a screen take an aluminum can and cut a couple disks out of the aluminum using scissors, about the size of a quarter or nickel. with a pointy knife, carefully holding it by the tip of the blade pinched between your fingers (trying to describe the technique to hold the knife blade so you can...

I hope we've had a nice holliday and got some rest, and arent so snippy now. I understand that some actually do attack you/your theories so Im not bothered if you get stuck in defensive mode. Ill give up that those are some good points, not entirely wrong, but Id still argue that there is a...

Lol maybe true, and Im far from worked up. Im just pretty enthusiastic about this lighting method that essentially takes the principles behind LED and makes it actually work without dealing with shitty chinese diodes with false claims of their wattage/output. Maybe Mr Rollitup isnt an asshole...

ummm https://www.rollitup.org/indoor-growing/358190-led-without-leds-my-first.html <-- 1800 posts in 4 months and only a fraction of T5 growers are even aware this thread exists. Someone may see the heading for T5's and click on it then learn alot of info they may not have been able to find...

:hump:

Obviously has no idea about the differences in techniques, tecnology and theory behind advanced PAR T5 growing, and your average CFL stealth cab grow or computer box grow. Obviously has no idea that there is an entire community of T5 growers who are hanging out on a hijacked grow log because...

Festivus, Yes! Bagels, No!

Most tube manufacturers source their tri-band phosphors from China, where they predominantly have a peak at 610nm and 549nm. Blue phosphors are much more widely available and researched due to demand for Aquarium use, but unfortunately horticultural fluorescents arent used commercially for...

This graph for the Aquaticlife 650 (not a bad bulb either) shows that while the peak on an SPD may not be the highest, it can still be the dominant output color. The red spike in this graph is not very high at all, but it is wide and comprises the highest percentage of output. Sure the green...

Im glad someone else brought up the heat lamp issue... I was getting worried having gone through so many posts without anyone mentioning it. Not just bad, HORRIBLE idea to use a heat lamp for so many reasons. No disrespect, and no I didnt even look at the links to your pics (to insert a pic...

hmmm... could be, I just google image searched it and came up with the other one. If that one came from them, I'd take yours as accurate then... and it doesnt look that bad either. I'd say even with this graph I'd still use it as a replacement for a 6500k or other daylight bulb in my...

Dont get me wrong, I dont think the Fiji's would be a bad bulb, Im sure they have some good blue in them, its hard to find a tube that isnt loaded with useful blues. I just want to know where the Red in them peaks at... is it under 600nm or over 700nm? Does the red just make it look pretty or...

We already know the CoralWaves are pretty much a blue bulb with a far red spike at 760nm which is out of the PAR range (but is useful to help induce flowering, not so much for photosynthesis) The Red Suns spike at 630nm which lines up w chlorophyll B and the Fiji Purps SUPPOSEDLy have a 660nm...

Just a pic to show how I attach a cheap ass desk fan to my fixture with a binder clip to blow down the length of my tubes. Its really easy with the Radiion 4 bulb fixtures cuz they have the plug on the end to Daisy Chain with. *as you can see, my leaves are just reaching up towards the...

Flora Suns look alot like RedWaves. They would prob look alot like Fiji Purps or Coral Waves if they didnt have the green spike in em I like the 660 spike, its rare. and the red peak is kinda short but its wide, showing a majority of its output in the red range.

For vegging Id almost be willing to put money that the one with more Fiji's will do better for veg, they have the full blue spectrum as well as the red peak where the Red Suns are almost all Red, and blue wavelengths are needed prominently over red in Veg phase. I'd be interested in seeing a t5...

Yeah those dimensions are about right. They are pretty compact units, only 2-3 inches high also. The 8 bulb unit is almost the same as the 4 bulb, but the reflectors are a little wider and they put 2 bulbs in each, so they are a little less efficient due to re-strike as the tubes shine on each...

My 2cents = you can almost get 2 cheap units off ebay for the cost of a BadBoy, they are almost a clone of the SunBurst units. I'd say most of the quality you're seeking from a T5 unit would be from the Bulbs#1 and the reflector #2 (individual reflectors trumps bulbs that are doubled up 2 to a...
