GPS's posts are either a clear demonstration of this lack of knowledge or a bad joke. Reading and learning something about lighting/electricity would help in these discussions.

You can take exception with all you want, that's your prerogative. And remember I can do the same. But I can tell you that I'm very comfortable with my knowledge (not that I know everything), and I simply wont be bullied into believing something just because someone that I don't knows demands it. Even in 7'th and 8'th grade, my science teacher (same teacher both years) would have the entire room set up as a lab at least once a week. Where we had to disassemble things like lamps, motors etc. at different station's around the room, explain all the parts and their function, then put it all back together so it works properly. My high high school auto shop teacher that I had for 5 semesters did exactly the same thing (including alternators and starters)' except we each had one at our own desk that we had to do by ourselves.

I also took electronics in High school for two semesters, and along with the textbook learning we had to build things like small radios from kits, making all the solder connections in the right places ourselves. Beyond school, I have also replaced all the electrical outlets (including all GFI outlets) in my moms old house. That includes behind the refrigerator and under counters like for the disposal. I also updated all the electrical switches in that house to the flat switches. There wasn't a outlet or switch that didn't get replaced, including all outlets and switches outside and in the garage.

I have also replaced the florescent lighting (including ballasts) in the kitchen, striped the wood molding and refinished it to give it a updated look. I have also added new security lighting in both the front and back of the house, and added an outdoor light fixture in the atrium, as well as installed the new electrical boxes for all the new light switches. That included cutting into the drywall and mounting them to the studs. Not to mention all the miscellaneous things like replacing existing light fixtures, door bells, thermostats etc.. Through all of that only once did I ever have a problem. There were two outlets where the voltage output was low (80-90 volts), and even after replacing them again it was still low. So we called a electrician in and he not only told me that I did a great job saving my mom thousands of dollars, but he also said the problem had nothing to do with my work. It was due to a ground short within the wall, and I would probably never have found it.


So again I don't clam to know everything, but I'm far from ignorant about electricity also, and I'm very comfortable with what I do know. Even if you don't like it. So when you say

find the # of lumens for a lamp and divide by the number of watts....

Then when I give an example based on exactly what you stated "you have a florescent light that puts out 10,000 lumens at 100 watts. 10,000 divided by 100= 100. Is that 100 kilowatts?" this is your reply

Watts/1000 = kilowatts
(Lamp watts/1000) X hours of operation = kilowatt hours
KWH X cost/kwh = cost

The problem here is you forgot to answer the question. You mention lamp watts, watts, kilowatts, but never mention lumens. The whole basis of your theory and the point of my question (in response to "find the # of lumens for a lamp and divide by the number of watts....") You simply started with watts and convert watts into kilowatts. So where's the lumen's you so adamantly referred to? You don't even seem to know. I gave you plenty of opportunity to explain, you just can't. Yet, you expect me to just believe you because you say so, even when you can't seem to figure it out yourself. Even if I wanted to, you have not supplied an accurate equation (showing your work) to calculate it with that would help anyone. You also have not supplied any information other than just your say so on your flawed theory. Talk about a joke, that's a good one.

Then to top that off you get offended when I choose not to believe in that theory. Then you resort to attacking my intelligence because I don't believe in your "divide lumens by watts" theory, rather than simply supplying links to sources that would support your theory. Again, that's what a real joke looks like.

You, sir, are a poseur and your ignorance is not a virtue.

That's the term - an Ignorant, that wants to look smart by all means. The worst part though, is that it goes at the expense and credibility of others who actually know what they are talking about.

Mobbing and scaring away any knowledgeable contributers keeps him safe from facing the bitter truth.

Calling me names defeats any purpose, and clearly shows your immature mentality. You obviously cant explain your own statement, and you want to call me ignorant. That's about as funny as it comes. But I guess it must suck when you cant find any creditable facts to support your theory, and you want blame me for that. FYI, bulling me won't work. But that doesn't stop bully's from trying, after all that's all they know how to do (they just haven't learned good social skills). I feel bad that your not able to answer the question and explain your statements, but that's just not my falt.

The worst part though, is that it goes at the expense and credibility of others who actually know what they are talking about.

Appointing yourself a knowledgeable contributor, and creditable source simply does not count, anybody can do that (including me if I wanted to). If you had your way, you would be crowned the only person on the planet that knows anything about anything. Just because you don't like it, you simply say that others don't know what they are talking about, like as if you were the only person that did. You simply want to keep other people from giving their opinions if you don't like them, just like a dictator. You simply don't know how to disagree with someone without putting them down.

Even if you did have some "special knowledge", it still doesn't give you license/right to keep others from speaking, and/or treat them with disrespect. That's exactly what you do time and time again without provocation, and you don't see any problem with that. Even if you were given a degree from the university of hydroponics (as you would like to claim), your still a worthless human being because of the lack of respect/courtesy you treat others with. That would just make you a worthless human being with a degree, but still worthless nun the less.

I have nothing to do with the way you were raised, so blaming me for your lack of character is laughable at best. You can cry about it all you want, but you simply need to give respect in order to get respect, something your parents should have taught a long time ago. You can't blame me or the world because they failed at doing that. Now you want to go through life trying to bully people into accepting your abuse, then crying about it if they don't. That's the bitter truth here. Cry all you want to, including all your "Oh woo is me", and "Oh poor me" stuff. Your simply not bright enough to understand the consequences of your actions. If I was your parent that wouldn't be an issue, you would have learned right from wrong as well as respect before you were 10 years old.

Now that that's hopefully over.

I'm wondering, if you're able to put the cfl or other fluorescents (sp?) closer to the canopy does that effect the number of lumens that the plants are able to use? Because if watt for watt the CFL's or fluorescent tubes are just as good because they can be closer, then because of the lack of heat this seems like the best answer.

Yes, the distance of the light is from the plant canopy defiantly does affects the plants usable lumens. This is true for all artificial lighting. But in the case of florescent, the amount of usable lumens drops off much faster than MH or hps lighting. Therefor floresent lighting should be placed as close as possible without burning the leaves. If it's to hot to hold your hand there it's too hot for the plant, or use a small thermometer to see how warm it is at the top of the plant canopy. Most plants like it around 85 degrees F, however lettuce plants like it cooler, around 75 degrees F.

Because if watt for watt the CFL's or fluorescent tubes are just as good because they can be closer, then because of the lack of heat this seems like the best answer.

Watt for watt florescent lighting is NOT as good as HID (MH and/or HPS), but florescent are a good for growing some plants. Mostly low light requirement plants like lettuce. Basically plants that do well in shaded areas, and/or seedlings. But florescent's need to be placed as close to the plant as possible to get the most usable light.
