That, is simply delusional!

The wet:dry weight ratio for cannabis is about 7:1!
Trimmed, an dried properly, your actual yield was less than 2 grams.

I'm still looking for trees in your photo album.

Oh, Wait! you don't have any photo albums do ya?

When, and if, you ever do post acceptable results, be sure to include plenty of "photon flux readings", OK?

I don't mind you creating a phony persona here, lotsa folks do that.
But using it to dispense bad advice that can affect patients medication is not acceptable.
Please stop doing that.

Yer gettin' on my nerves,

I don't understand the vitriol.

You want to claim horseshit but when people want to know just how well their lights perform - you're going to want numbers.

Calling me phony makes me pretty sad. Especially when I just finished yet ANOTHER system that can cut the LED power you need by HALF.

And there it is.

Plain and simple, Weezard - I only deal with RAW science. If you remember, that blue led was an EXPERIMENT (even listed as such) so your calling bullshit on a mere "I wonder if this will work" project is rather uncalled for.

Phony, wow. I had thought better of you Weezard, maybe I thought wrong?

And yes, I will include photon flux readings. In fact, let me go ahead and provide you a relevant link.

Seriously, you know some good stuff, man, but when it comes to actual photobiology, your bare-necessities approach still has limitations. You completely forget the Pr/Pfr reaction where chlorophyll first prefers a 660nm or so photon, then after it receives that it PREFERS to receive a 720-760nm photon. There's also a blue-based version of this as well, working from 460nm photons first and preferring to receive a 390nm photon afterwards.

khyberkitsune Reviewed by khyberkitsune on . RM's Bicolor DIY LED lamp vs a Commerical unit I have two DIY LED lamps that I am experimenting with. An all white one posted in another thread and this bi-color update to my first DIY LED. Originally it was a 20 watt (2 * 10w) 465nm seedling & veg lamp and I just finished adding 24 watts (8 X 3 watts) of deep red 660nm and 24 watts (8 X 3 watts) of royal blue 445nm. It is impossible to compare the brightness by eye alone because of the differing spectrums, LED wattages and spacing, but I would wager my 68w passive cooled is easily Rating: 5
