THIS is what I mean be retards spreading rumors...I don't mean everyone is a tard...just the people who believe in something totally wrong and spread the incorrect information.



a so-so post. yea Mylar isn't THAT superior but plain ol every day flat white paint isn't in the same ball park with good reflective materials.

Getting dirty? What makes you think a painted surface doesn't get as dirty? I'm guessing it's because you can't SEE the dirt that you think it's not as dirty. Truth is, it doesn't matter what you use, it gets dirty at the same rate.

Flat paint? No, you should at least use an egg shell sheen. If you are using floros you should use a high gloss if possible.

If you want to use paint at all, buy a premium brand of roof coating (Cool Seal) which reflects about 95% of all light.

The problem with flat white paint is it reflects less than 70% of all light (key word here is ALL as the light you and I see is useless to plants). In reality, the thermal blankets (sold at most sporting goods stores in the camping section for $2.00) or the mirror like gift wrap reflect roughly 80% and are superior to flat white paint. I strongly suggest you only use these if you are using floros however.

Where I agree with this poster is I would take paint over mylar with HID lights. Where a wrinkle could cause a "hot spot" a painted surface won't.

Again I apologize for all the "retard" comments. I hate when I hear (on a forum or in real life) "I just read xxx is true dude! You should be doing that!" People don't take the time to find out the guy that posted xxx is a retard...and they become a retard as well for spreading the...well....tardness!



Actually urine is a great fert. It's sterile as well. Very high in Nitrogen, but the problem is it's too strong and as it decays it invites bacteria that wouldn't normally be attracted to your soil. Unless you have a perfect environment, I wouldn't recommend it either.

Well at least you found some of my info correct but you're way off on some things, so let me try to correct them:

Shiny paint (gloss or eggshell) has an additive in it to give that sheen. Just because you can see a shine doesn't mean it's more effective than flat, in fact quite the opposite.

The white in the paint is the only thing actually reflecting the spectrum. The light has to pass through the gloss first, then reflect off the white then reflect back through the gloss. You loose more light with any amount of gloss in a paint at all and it actally makes a pretty big difference. It's like light through a window vs straight light.
Plus gloss white hot spots as you said.


The difference between dirty mylar and dirty paint has simply to do with how much easier it is to clean or repaint the paint, and I suggested just repainting the paint as often as every couple grows. It's easy as hell to run a roller over a wall with some paint and no way in the world are you cleaning mylar that easily. If someone is I think we would all love to hear about it.


Beyond all this: One problem with mylar that I didn't even mention is it is directionally relective only and distributes light very poorly. Just as would happen trying to bank a ball in a game of pool a 30 degree incoming angle goes out at an equal 30 degrees. Usually that means a lot of your light directed exactly where it does no good at all. Figure out your angles. Additionally mylar is gray, automatically. If you understand how we see color you'd know that mylar isn't going to refect back as much light spectrum as white. What we see as color is the color that something ISN'T. That's the color that whatever you're looking reflects, and that reflected light is what's picked up by the eye. So essentially when you see green, it's every color except green, which is why you see green. White is no color. It absorbs nothing and scatters light evenly. The only loss from refected light off a flat white is the strength of the light. The spectrum is virtually unaltered.

There is ample evidence like what I said in the last two paragraphs that flat white may in fact be superior period in how it reflects light compared to mylar but that would have been too controversial and there is not enough scientific evidence of direct comparisons in grow situations that I'm aware of to support my taking a firm stand on that without having to argue that to death, so I didn't claim it at all originally but did now only to try and explain more of the how and the why.

Anything else anyone questions about this subject though I'll try to answer, but I'm no scientist I just happen to know a few things.

I think I will break this out into it's own thread tomorrow.. I'm tired now.

You can even add some very common additives to make flat white even more reflective than it already is, but that can be quite troublesome...

This ones a little tricky.

Plants start their life in a growth stage. The seed has enough food to get 1 root (tap root) and to produce a seedling leaf. So the first order of business is to produce roots and more leafs. Durring the veg stage the plant is rooting as fast as the plant is big. (good clones). Once you switch to flowering the root production is almost at a hault. Now the energy is directed to flowering.

Plants have one goal in life, Survival the bi product just happens to be O2. So yes if you clone a flowering plant it will go back to rooting but under a lot of stress. The plants can be deformed and 25-50% smaller. But since you are at the begining of the grow (clone stage) Its better to just start over.

All I know is what I have seen. Bought 3 k-train clones fully flowered with red hairs in 1" rockwool with basically no roots. I am cheap and didn't want to waste the genetics or smoke a $45 gram...so I babied them through the re-veg process. To say it is cool to do this, just leads to people like the dude I bought them from doing it and saying he does it all the time. I have re-veged twice. the process is SLOW! Though I totally recommend it if you have room. And if you must clone in flower keep them or give them away.

Yeah like straight up liars! Still working for investors looking to put money into a cannabis forum? Or how about getting a pound per plant (wet) using fluorescent lighting? This isn't a nice chicks thread so I am not going to be as nice here I really doubt you are even old enough to be on here, much less to pop in and tell HOHO to "get over it" At least you didn't make up some blatant b.s. here, so I guess I should cut you some slack

you're funny man...but in a strange way. I'm 43 today, and yes I work for a company that buys forums. Really wished I could tell you more about that, but you probably wouldn't believe me.

Pound per plant wasn't a joke/lie/whatever...but if you read I said WET. I think most of the flamers for that missed the wet part. I don't really care, I've got more interesting things to do than prove my accomplishments to people I don't know.

I do find it interesting however, there's tons of posts and even videos of people who did far better, and that's why I said I wanted to shoot for 2 next round. Unfortunately I was sucked in by the HID outfit, and it's going to be very difficult to be as patient with a floro grow ever again.

Now if you're done attacking me, we'll part ways, agreeing to disagree. If not...well it's obvious matching wits with kids is pointless.

Nothing better than ending a post pleading for mercy with a jab!

Its so funny, cuz i remember like 2 days ago when i read what you wrote and i saw you said "wet", i said to myself "i wonder how many retards are gonna try to call him on getting a pound of of one plant."

LOL

Before you start calling people "retards" maybe you should read my post and the portion of my post quoted by bluediemond. They both have wet in parenthesis. I noticed the "wet" the first time I read his B.S. in https://www.rollitup.org/general-marijuana-growing/141398-read-then-ask.html

I noticed it then and have no problem with a wet weight as others have. I would weigh wet also to get an idea of final yield. So I just automatically make the ~25% of wet yield. That is still 3#'s or 1344 grams. Going by the 1/2g per watt using hid lights that is 2688 watts. But he claims to have done this not only with fluorescent lights but his first time, and he doesn't smoke.

2688w HID = ~137.5 lumens/watt. T5 fluorescent bulbs (which he did not claim to use) produce ~90 lumens/watt.

So: 2688 watts of HID lighting = ~369,600 lumens
To get the same lumens from T5's you would need ~4,106 watts. That's 76 T5's!!!!! Regular T8's doo not have the same output but assuming they did it would be 102 4 ft 40watt bulbs.

I know all this lumen stuff may mot be linear, but this just gives more validity to the fact that he is full of crap. He claims that it was flouro and natural lighting which though possible, without a greenhouse that has black out capabilities (huge cost) it would be major pain in the ass...to not even smoke it....

I think I understand your thinking but mylar is superior to white paint. You only need a lux meter to test it for yourself. First of all, white paint absorbs significantly amount of light. Although you are correct that the 'color' white reflects more light than any other color but if you remember, white is subjective, and it is meaningful only to how people perceive light, not plants. That means it isn't reflecting all colors equally but is reflecting more green light than reds and blues. Secondly, mylar isn't gray, it is silvered, which means reflective, just like a mirror. But unlike a mirror, the reflective surface isn't below a plane of glass. Mylar could be analogous to the surface-silvered mirrors used in laboratories to reflect laser light.
I don't remember the numbers, but IIRC, white paint tops out at about 80% reflectivity and mylar around 92-95%. Also, I don't know if those measurements are taken with a lux meter, but if so, that means that it's reflective properties for the red and blue ends of the spectrum is even less. If you want to use UVB during flowering, I wouldn't count on white paint to be especially reflective of these very short wavelengths but I bet mylar and other silvered surfaces will reflect the UV light just fine.

What do you expect for a first time grower that read for a couple of weeks. Of course he knows more then anyone else. What is wrong with you people, can't you see he is an expert? After all, how may of you can say you read for a couple of weeks on the internet and you were not an expert? Of course you are. No need for schools or degrees or anything, just read up on what ever you want to do on the internet and you too can be an expert.

Can you spell brain surgeon? That actually takes 3 weeks of internet reading....

panhead recently ended an experiment about Dutchmasters Reverse that i found very interesting,it does not stop hermies but there are somethings that are unexplained about this product like 100% female from seed that were not feminized seeds(for a short time though) so basically if you find hermies and think you can just order this stuff and fix your problem it won't work. hope the link worked

OMG neg rep! I should just shoot myself!

You ever consider "rep" is pointless and the advice I've offered is spot on?

The "rep" system is what continues to make this a kid's site. Half the posts on here beg for rep....personally I'd like to see how low it gets just to show how little it means to me.

If you saw something I posted that was wrong, prove it.

Okay guys, heres my opinion, take it or leave it.
#1. Everyone needs to smoke some of that great dope they're growing and chill the fuck out.
#2 Miracle gro & bagseed are completely viable options.
...having said that, currently drying some GH cheese that is the nicest looking dope i've ever seen.
#3. Bluediamond is full of shit.
A little excerpt from his thread:
"From what I've learned I'm currently harvesting apple white widow. We did a fast dry of a bud for test....it smells and tastes like apple, but smokes and has the same effects as white widow."
You cant just taste weed and arbitrarily decide it is a certain (made up) strain, thats not only silly, its misleading. And with all due respect, you can't know shit about weed if you don't smoke it. You're like the football coach whos never been on the field before, it doesnt work.
I can only assume that you are unsatisfied with your life and have to take out your anger unprovoked on these good people who are just trying to promote the free exchange of ideas, you are everything that is wrong in this world.
#4. Expensive soils are for suckers, as previously stated, you can ammend cheepo homedepot soil and have it be just as effective at the fancy stuff that is ten times as much to buy. It's all about what you put into it.
#5. The ground wire is ALWAYS important, especially in wet environments, surrounded by stoned (clumsy) gardeners.
#6. Trichomes are produced for alot of reasons. They act as magnets for pollen, act as a shield from pests, and are the plants' natural defence. "i'm hungry i'm gonna eat some of this....... WHOAH MAN" of course this is like trying to tell you why you have an appendix, we might be able to explain it, but it doesn't mean we're right.
#9. I am high as fuck right now....
#c) Weed can and will make you hallucinate. cant smoke it fast enough? eat some of my cookies, they'll make you feel like a rookie.
#420. "Feminized" seeds come from females that have been forced hermie, a naturally occuring hermie is of no real use for breeding.
#36473. I hate to admit this one, but people have died from marijuana before, not so much from ODs but from heart problems that are exaserbated by being high as shit (a strong sativa will make your heart go boomdeeboomboom). Also lets not forget about impaired drivers, i like to think i can drive stoned, but i'm positive that someone at sometime got too high and slid off a bridge or some other terrible fate.
#10. birth control pills are about as effective as punching a rusty nail through your stem, just another magic snake oil that has never been shown to do anything usefull.
#11. And heres where i destroy my credibility in all your eyes, The idea that you can harvest earlier for a more "heady" high is bunk. There is an ideal window in which to harvest marijuana when its THC is at its highest levels, its my opinion that when you make the claim that an early harvest made for a uppier high you are simply not getting as high and getting a bit of a head rush from smoking unripe plant material. If you want a head high you should get yourself a long flowering sativa, something with more THCV or Tetrahydrocannabivarin, this will act as an antagonist to the THC and change the psychoactive effects, it used to be thought that this was a precurser to THC that would make the transforamation via certain enzymes reacting , its now beleived that the cannabinoid profile of marijuana is, for the most part, genetaically determined Having said that, over a long period of time THC will break down into CBN (among other things) which is more associated with the heavy, stoney feelings. But this only takes place well after a plant is past its ideal harvest window and is therefore (in my eyes) irrelevant.

Just my 2 cents.
MYTH.... plausable?
