Thats because you have an unimpressive light. Even mid range LED grow lights that work are $$$
This Bhut Jolokia 9 months old was grown with only LED lighting.

If I was made of money I would use this light in my grow tent.
Instead I have a few of these. The one on the plant in the...
Really, I thought it was the other way around? Where did you read about it? I just remember someone made an offhand remark about an LED study that showed the blueish light you get when the light is filtered by a canopy of covering foliage promotes branching of the underlying foliage. A kind of...
Doppler broadening is the broadening of spectral lines do the temperature of the stuff emitting the light. Temperature translates to atoms and molecules jiggling around. The hotter something is the faster the atoms are bumping around. In analog to sound waves when the atom/molecule is moving...
It has optics. They are built onto the LED chip. They range from a 120 degree lens to 60 degrees. The UV LED is pure UV and looks like a dead chip (i.e. no visible light).
I don't know how geeky you are but I'll delve into my thoughts about the white light. The spectrum of atoms and molecules are dictated by the number of atomic transitions of a particular species and in molecules there is a complex interplay between the atoms in the molecule that allow for many...
Good info. I have looked up most of this before though not the same depth (I didn't look into carotenoid's). Right now Im using this on some Butch T's that I just started. We'll see how it goes. I have a small one that keeps a Ghost Pepper going in my house (it is very very bushy) Even though it...
Right, so the PAR sensor is picking up green which is not what the plant needs, so while the band-gap is in the photo reactive region for plants it still doesn't have a perfect bias. Unless Im missing something and the sensor can break up the light into spectral bands. Sunlight isn't really a...
Cool setup. I'll have to read more of the thread later. I'm doing a setup with mid range LED's in a grow tent. I would like to know for sure if filling in with white does anything. What is the spectral sensitivity of a par meter? What is it using to guess what a plant wants?
Howdy, I would like to purchase some 7 pod brain strain seeds. I just started growing peppers indoors with a little success (Bhut Jolokia)
Cheers!
