**ULTIMATE LED TEST** *Grow LED Hydro* VS *Blackstar* VS *Hydro Grow LED*

[GrowBigTV]

I am still working out how to correlate your data with the experiment that I am going to do. I am glad to see yours though, and your work should help in determining the level of "tuned" light needed for quality grows. My experiment is going to be under scrog... so the lights will be much closer than what you are working with. Secondly, I have a fixed space that needs to be lit, 2'x2'... so figuring out how many 5w and 3w lights in my custom lights in that configuration is equal to each of your lights working at a larger distance from the plants as well as larger surface area ... it is making my head hurt. Comparing your Spectra with the Penetrator is probably going to be the closest thing to my experiment, which is going to be 3 controlled stations... one T5-HO, and then 2 LED stations, one twice as many watts as the other.
The more of us that experiment and prove that LED is an effective way to go, the faster this technology will become commonplace, and eventually the prices of the LEDs will come down. I am convinced that this is how best to reduce the costs associated with this hobby. Thank you again for what you are doing. I will will be watching carefully to see the density of the budz developing in each of your stations as well as trichome development and please let us know if any in the group look to you like they are maturing a bit faster than the rest... it's sometimes hard to see from here in the pretty red light.

Your welcome! I'm glad to know there are some following along on the grow.

I would say at this point it looks like the Blackstar is in the lead by a bit, and the Spectra and Penetrator are about equal all the way around.

Blackstar in the middle with the Brand new Spectra 150s.

These will be coming out in a few weeks with the new website for GLH. Michael asked me to ask yall to bare with the old site in the meanwhile.

"The 150's use 3w true 45ml chips, red and blue wavelengths use 90* lens and the two different white led's use 120* lenses. The true draw of the panel is around 155w and uses 100 individual led's."

QUESTION:

Should I leave the Spectra 300 in, or should I replace with the new Spectra 150'?s

(The 300 model is going to discontinue so all that will be available will be the 150's in the near future)

hi growbigtv.
if i was you i would put in the two new ones since this will be the ones that people will be investing in from now on(or at least very soon)
keep up your good work

I plan to switch the lights out when these LA Cons are chopped (approx 5 weeks)

GrowBigTv- I appreciate your effort on your endeavor. I notice that under Penetrator and Spectra the leaves are some what droopy whereas Blackstar produces healthy looking leaves.

I will be setting up a LED grow room sometime soon. I wonder if differing ratios of red and blue spectrum have any significant effect on growing and flowering

They most definitely do! Make sure to do your research before you build your room, especially if you plan on building your own panel.
