Right behind ya brah.
Why would you wonder?

Sent you a private message via reputation.
Guess you missed it.

Apology accepted.
Mahalo fo' dat. I had completely forgotten.
No worry, I understood your position.
Did not see it as a personal attack.
Saw it as a reaction to unexpected results.
( I get a lot of that)

Didn't believe it myself when I first started reading about LED growing.
That's why I had to try it in the first place.
The science was sound, but it had a ring of "too good to be true" about it.

In retrospect, it should have been obvious to me because the sun is such a harsh master.
At noon, in the tropics solar exposure exceeds 91K Lux.
Cannabis stops growing at ~90. unless you supplement CO2.
Even then it pushes transpiration to capacity.
Meanwhile, the UV b-c is frying off capitate glands, overheating leaves and stem, heating and drying roots near the surface, yadda yadda.
Homeless plants have a hard life here.

So, I shield them from harmful wavelengths.
Give them sufficient, (but not too much), light energy at the most efficient wavelengths.
Feed them appropriately, insure an ample supply of aerated water and a pest free home.

With all that in mind.
My results were predictable.

So, fuggedaboudit!
There was no offence.

Aloha nui, an' how does your garden grow?

Weezard Reviewed by Weezard on . Calling out to Weezard for LED advice My friend, I've read your stuff here and at Steve F.'s site. I want to build a dedicated flowering lamp using Ledengin 15 watters. (4 reds, 1 blue, and possibly 1 warm white; LM 317's so I can tweak the ratios.) Essentially, a copy of your 4+1 cake pan lamp but built on a 4 x 18" finned heatsink so I can see what's going on under it.) If I were to post my picks for power supply, resistor ratings / values, etc., would you critique and perhaps offer some guidance? I have already purchased Rating: 5
