Excellent point,But to clarify I was simply dreaming up an idea for an LED sugar light that could be affixed to ones existing HID reflector. And the idea of induction was just an idea to drive the thing without use of additional wires or timers.

I met Mr. Rosenthal at a book signing in Chico CA circa 2000, the man is totally smoked. I was totally unable to have any form of intelligible conversation with him. He was unable to answer any of the very specific questions I was asking him. Then he signed a little boys skateboard and tried...

Great charts! That's all hXXp://www.marijuanagrowershq.com/category/lighting/inverse square law real simple stuff when you boil it down. Now as far as how many plants?!? I imagine you can expect great coverage from youro 1000w for a 4'x4' but could stretch that to 5'x5' if you wanted. Use of...

All so interesting. I'm sure that too much UVB 'therapy' would not only inhibit the plant but could in fact kill it. I imagine the next question would be in regard to dosage. That being said, how in the hell would you measure UVB light intensity? I have a PAR meter but I don't think it's...

There's a book on this subject?! Please share the title. I'm not sure if light in the 450nm spectrum is going to accomplish the same thing. 450nm is just at the cusp of viable light spectrum, actinic lighting is for aquariums isn't it? Love the ideas, keep it comming

Please forgive If this has already been brought before the community, I did not search the forum prior to posting. It would seem that there is some sort of coalition between THC production and exposure to UV lighting. This effect has been sited by several biologists. Ultraviolet light between...

Love it, I have always wanted a grow room attached to a greenhouse so that I can vent lamp heat into the greenhouse. What a wonderful set up!

You go girl

The problem with planting seeds in such a large pot is that it makes it hard to regulate soil moisture. I'm sure it will be ok but for future reference smaller cans for smaller plants. Also the 600, if used should be quite high to reduce the light intensity and heat...

As far as the older inductive type go, hydrofarm make something they call thejxxp://www.hydrofarm.com/pb_detail.php?itemid=3497"]powerhouse. Copper coils are copper coils but what sets this one aside is that the transformer is located at the top, this is important because it tends to cook the...

Now may be a good time to consider selective removal of some of those huge leaves. plants need leaves of course so take just the ones that may be shading. Maybe too go through lower portions of the plant and remove any of the popcorny stuff that won't amount to much. Looks good though. In...

In this most exultant article you mention that EJ has little to no customer service. Well this is exactly the case, but i would like to share a bit of an insider tip with you. Ej is made in a warehouse near the airport in Chico, CA. EJ is part of a company chain owned by a married couple...
