I have not tested. Plans are to either to set up a lab in Colorado to do some testing or work with someone in Co (or other legal state) that will do the testing for me if I provide the equipment. From what I read, the THC increase can be from 5% to those playing around...

> I'm pretty tapped out right now In a few months when my uvb grow lights are finished, I will shoot you some to test out. Can't beat free.

I would not cut back at this point because guessing, you could have a lot more UVB to maximize your THC. Their website suggests using only their lights for up to 19 hours a day. You might try getting some single T5 fixtures with reflector and hang them vertically so that the light is nearer the...

Yeah, bright white reflectors surprised me too. The best commonly available reflector is highly polished aluminum with no clear coat. Simply putting clear coat to prevent corrosion, makes the reflectivity equal to bright white with a flat finish. I suspect that Mylar film is similar in...

> This is all new to me so any advice from those that have experience would be welcome. I am developing 10 different models of 24 watt CFL grow lights. Some of these models will have UVB... so I have been researching the use of UVB for quite some time. Simply put, the plant's reason to make THC...

Cool reflector. My guess is that you will get much higher reflectivity by painting it with a "flat bright white" OR lining it with mylar.

Can you please tell me the number of each type of bulb you are using? I found links to: Agromax Pure Par - http://www.htgsupply.com/Product-AgroMax-4ft-T5-Pure-Par-Bulbs Horti Powerveg UV - http://www.eyehortilux.com/products/power-veg.aspx Can you please help me out with a link to Agromax Pure...

"fun in the sack" ... thank for sharing your perspective. Sex makes the world go round.

Lumens is a measurement of how humans "perceive" light, so when it comes to plants lumens is pretty close to a useless figure. If you can give me link on the lamp you plan to buy, then I can do some research for you to see if it will meet your needs.

You should not be looking at watts. Rather you should be looking for either Photosynthetic Photon Flux (PPF) or Photosynthetic Photon Flux Density (PPFD)... these figures are your friend because plants don't eat watts, they eat photons. You should ask the supplier for their PPF or PPFD. It needs...

Sorry for the delay in answering, been busy. I have complete test results on a TaoTronics_TT-GL20 12 watt LED lamp that also has the approximate same blue/red ratio as your lamp. It has... Consumed Watts: 9.8 PPF(Photosynthetic Photon Flux): 10.82 μmol/s Based on this, I made a PPF estimate for...

Is this the LED you are using? http://www.amazon.com/dp/B009L2VGCO http://www.lampsplus.com/products/21-watt-par30-led-grow-spot-light-bulb__x0476.html Can't seem to find much useful information on the bulb. How many blue and how many red leds are there? Also, do you know the "true wattage...

Yes. The plants don't care where the light comes from. What they mostly care about is the amount of Photosynthetic Photon Flux measured in μmol/s or Photosynthetic Photon Flux Density measured in μmol/s/meter². They also care about color balance, for instance white light is typically composed of...

Spectrum data files from a spectrometer typically have columns for nm (wavelength) and Pe (Radiant Power/Flux in mW), but plants don't give a rip about Radiant Power... they only care about photons of light (Photon Flux). So I have been on a quest to Convert Radiant Power/Flux per nm to Photon...
