me too. :jointsmile: perhaps I should revise and restate remarks. :D I take anything Weez and St8 say about led growing as fact. the proof is in the buds. :rasta:Quote:

^ kinda off topic but I was thinking about the lite brite grow kits and it occured to me since led can be put right against the plant without burning them then how about a string of led lights that wraps around the plant kinda like a string of Christmas lights wrapped around a Christmas tree? :detective1: I bet someone else has thought of this already but if not what you guys think??
Indeed they have.Quote:

Lemme 'splain.
There is such a thing as too much light.
And, of course, too little light.
Somewhere in-between is the "sweet spot" for cannabis.
If you place the source right against the leaf, there is no room for adjustment and each emitter only covers a very, very small area!
To cover a decent size plant that way. would require thousands of weak emitters.
Mo' betta, to use hi-power emitters from several inches away.
Better "blending" too.
I suggest that you google "Inverse square law", read a bit, then sit and think about it.
Could save me a lot of typeing, yah?;)
I'm saying that you are on the right track, but you need to gather facts, then spend some time and effort thinking about it.
All will become clear in time.:D
Aloha,
Weeze
^ cool. thanks Weez. Inverse square law, eh? gonna search that now.
yeah, after I thought about it a while I started thinking about some of the very same things you just mentioned. maybe wrap the lights around the outside of them, like on a circular fence not actually touching them, for a little added umpf down lower. but, I'm thinking now maybe you need them somewhat proportional and reflected to get the correct wavelength. :stoned:
but you are right, a little R&D may needed at this juncture. :jointsmile:
ty, all that posted something.
i need a few 425-440 nm panels or spotlights and the same in 630 and 660 preferably just 660. anyone know where to get far red 730 also? thank you
The first (and likely only rule) when dealing with LED lighting, is CHECK THE SPEC. LED lights are good if you find ones with the proper wavelengths, the proper output, and a proper balance.
If you see "NASA Spec 7:1:1 or 8:1" RUN AWAY. Natural sunlight is NEVER that imbalanced, and the point of growing indoors is to emulate all the good outdoor stuff and exclude all the bad outdoor stuff.
White LEDs IMHO are a waste. I've got a quad-band LED panel with white diodes, and my tri-band does a little bit better.
Take your wattage, and divide that by the amount of diodes on the panel. Is the result 1 or greater? If not, it's not worth it, avoid it and look elsewhere.
Weezard, Stra8, they've got the pudding proof!
I've had great results as well, as you can see.
You can't listen to the marketing, because that's all it is - marketing. It's deceptive, misleading, and quite often flat-out BS.
Its the weezard!
You still have to give me a DIY workshop when I visit the islands. One day...
