no ones mentioned bleaching even after 5 pages?

Didn't have a problem with bleaching, but again, I use CFL and fluoros. I do get leaf burn. A tip here, a side there, no sweat.

You have to really pound the light to them to see bleaching. And to the guy that was say a 1K light has full lumens at 24" and loses by half for every inch after that you are spreading bad info bro. Lights of any ordinary type (HID included) are rated at 12" from the source and then the inverse square law applies from there. So actually at 24" you are actually recieving 25% of the rated lumens of the bulb and at 36" you are receiving 1/9 of the rated output.

Post no. 6 I believe BigV.....this guy Medi 1 knows everything, he's gonna be so pissed someone called him out once again!!

bIgv has obviously broke out the photo resistor and the ohmsmeter. Even though I know all this my bonnet will stay where it is, for full spread over the grow, and I'll still keep my 360w/of flouresent tubes. My clones go in at one foot high and within the first week they're over two feet and by the time they're done I have to keep them pushed back away from the bonnet. I lay my plants over by moving them by the roots when my table is flooded.

no why would i get pissy., its the childiswh comments that bother me not fact stuff. at least he ahd more info than....cause i say so...shows there is actualy less lumens at the distances i claimed. makes your light even worse. not better.
still waiting to see thios indoor crane holding the light....lol and if you raised the light even further away you get even more of that week footprint to light more of the room with less lumenhs
by the way big v we know each other if thats the same name on other forums.

Once again bulbs are NOT rated 12 inches from the bulb. Where did you come up with this notion? 99% of bulbs on the market are rated right at the bullb surface. Sorry but your inverse square theory was proven wrong in your own thread a few days ago.

ya i was just re reading that.
and here is more on it...but i guess its wrong to. i went by light meters not this math equations....says nothing about doing it a foot from the ligtht, says from source. to me that means a ligtht. not 1 foot from source.
and i need to say in a hood the law is out the window as well with the reflection

The inverse square law is correct when used moving away from the bulb. Bigv the other day using the 'rated 12 inches from bulb theory' tried to use it moving closer to the bulb from 12 inches to say a bulb puts out more lumens than it was rated at. Great notion but completely unfounded and wrong.

ya i saw someone the other day post a chart that has been onloine for years that shows the increase as well...start a 400 hps at 53k..and is right then at a distance it was about double....lol
i want one of them that increaees lumens at further diatnces...where do we buy them at....
i knew it was right as working where i do i have axcess to test this so called stoner theories out. most are wrong or dont get why things to do what they do or how
i will say with a hood depending on designs there is hotter and cooler ereas within this to, its not a perfect even flow of light. or perfect patterns but the basic science is there.

For like $20 you can get a light meter and figure for yourself how the light fades as you get further away.
Not being scientific or anything, But I can say that with the meter you'll easily see if the light gets cut in half when you double the distance from the light. It does not work that way.

I use a clear plastic garbage bag made into a mini greenhouse to do my clones. I put my flouresent coolwhite tubes on the ceiling and I put a shelf up to set my mini greenhouse on. It's up out of the way and it works great. Clear plastic gargage bags are really cheap. This is what others might refer to as a humidity dome but I call it the cloning bin, or the bin for short. You should keep your 250w bulb about one foot from your plant.

You will never see a pic of my op. But I will tell you that to set one up like mine you need 128 square feet of room. I don't write anything unless it's a proven fact, either proven by myself or fellow growers. The reason you(Medi 1) can't understand anything that I explain is because you work for a fertilizer company and you think about growing in conventional ways. The sun gives off way more light than any 1000w lightbulb anyway so...heavy duty 1000w lightbulb housings are extremely expensive and I can understand.

how do oyu prove anything with no equipment to probe it...your word isnt proof. i see people claim mg is ther bomb but thats not fact....lol
whats the sun have to do with what this is about. you keep going off on other subjects...i dont understand cause i work for a nute co....huh????. dam what a waste of all that skoolin i did then hey
just cause thersew something you do dont mean its the right way...nor totaly wrong...just your way is all. i try n post science or fatcsw then let them go from there to how far to the right way they want to go. but at least they know its fact...not an idea or though i had....the guy that has a 1k 4 foot from palnts...ya ok. your sayin the inverse square law is wrong...man all them proffessors must be fallin over by now then. when they call a theory law...there is no other explanation or variance to it. same as in breeding with mendals law in genetic traits. what you have is an idea...or theories
by the way...you ever hear the sayin....size dont matter. id say that also goes for room sizes. dont mean shit cause its a med size grow. some of the worst are commercial croppers like that. commercial and quality dont go in the same sentence

The inverse square law says that the light gets cut down to 25% when you double the distance from the light.
