I dont know where you read that? I said "I save money on cooling (NONE)"
Meaning I don't have to cool My growing area.
When I was using The HID i had to actively cool not only the light but ventilation as well.. More fans etc....
Try an Evaporative cooler! IT's less expensive than cooling with AC and given enough water can keep your temps down...i have a sunleaves 8 bulb 4ft and well it puts off some heat but temps still get up there. i am just trying to find a change
Thanks I might give this a try when I need to get new bulbs.9 bulbs total...3 to switch out
in this order too....
UVL 454 w/internal reflector
Fuji Purple
UVL Super Actinic w/internal reflector
ATI T5 12000K Aquablue Special
UVL 75.25 w/internal reflector
Fuji Purple
3. UVL Red Sun
when you bloom add the red sun bulbs where the actinic (blue) ones are (75.25, 454, Super Actinic)
http://www.aquariumspecialty.com/ for the lights...Would you mind pointing me in the right direction, possibly where you bought everything? I see you stalk the forum like I do ha
Yes the Plants LOVE the actinics!!! they will literally grow over to the blue bulbs(454 and the actinics!) in a few days if I dont turn them.I noticed you have the several spectums, are you noticing any of the plants possibly enjoying one of the spectrums more than another?
Interesting, I will have to look into this info. I too was under the impression 'green' light did your plants no good at all.Nice to find someone experimenting with spectrums. This is the very reason I decided not to get another LED. I get to play Sun God!
The Myth About Green (~ 500-600 nm), GSL (LED mfg) now incorporates a few green LEDs into his lights. He calls his lights 'Quantum'. From his website...
"Many scientists have long believed that plants absorb little to no light in the 500-600nm region of PAR, however new research has shown that light in this region plays a vital role in growth times, yield, and photosynthetic efficiency.
Plants convert light energy into chemical energy in a process known as photsynthesis. Two compounds, Chlorophyll A & B, are primarily responsible for this conversion process. These compounds absorb blue and red light most efficiently, and have the highest conversion rates at 439nm, 469nm, 642nm, and 670nm. Our Quantum lights target all 4 of these points, and then take the science one step further. Multiple tests have shown that plants absorb more red and blue light in the presence of green light, yet we are the only company to focus on this occurrence. Research published by NASA verifies that when all 3 regions of PAR are balanced properly (400-500nm, 500-600nm, & 600-700nm), flowering times and yields can be dramatically altered..."
and with that I have been on a quest for 1-2 4ft HOs to add to my mix. Anybody?
Yes there is plenty of research on the topic. And ill believe a PHD over a stoner any day.. Thats why im using my technique! i believe that by following the LED path with T5 i can get better yeild than LED at T5 efficiency and penetration. As you can see in my pics results are showing my method IS working and VERY well.. I have yet to see ANYONE show showing flowering results like mine with cheap "bloom" bulbs.I actually had a professor from Florida state come up to my university, he presented some very fascinating research on the subject of green light, and that it really did have a necessary role in plant growth.
