how about busting the great flushing myth, that flushing removes nutes & toxins from the plant?

or the myth that plants need high P bloom boosters during flower?

Well aside from maybe boosting "P" during late flower to produce "Stress" to increase resin production or "sugar" I believe high "P" screws up the most important part of the grow when everything needs to be at optimum... and more than the plant needs or wants is not optimum

Flushing seems to help people "feel" better . . . that's the why on that one

And Riddle I pm'ed u >>>please get back ...thanx

they say if you drink drink a pint of water straight without a break then light up a zoot immediately then you get SUPER DUPER HIGH on like the third toke! ive tried this and it does tend to get me higher than usual but not on the third toke i guess it might be dependant on strain, quality and the individual, but i recommend trying it!

there was also a myth when I was in college that any strain with the "White" in its name (e.g. White Widow, White Rhino) contained cocaine, lol i now know thats just stupid but i believed it at the time haha

One of my "favorite" myths is "Aluminum Foil causes hotspots", what a load of crap! I've said it before and I'll say it again - "Nobody has ever suffered from hotspots caused by using aluminum foil as a reflective material!".

It's a virtual impossibility - it would have to be like a ten billion-to-one, odds, coincidence. Besides, foil sucks as a reflective material anyway - it only has an index of something like 40%.

That one is NOT a myth.


GrowRoom Reflectivity Choosing the right surface for the walls of your grow room is very important, as up to 40% of your total yield comes from the edge, and the right wall surface can increase the amount of light those plants receive by up to 30%! Artificial lighting diminishes exponentially with distance, so it is important to ‘contain’ as much of this light as possible, and direct it accordingly. Reflective surfaces also help illuminate the lower portions of the garden, providing lower buds with light and heat energy.

To get the best results with your light and walls, it is important to get the walls as close as possible to your garden to ensure the least amount of light is wasted. As a caveat, the percentages provided are only useful as a general guideline, as they present the range of reflectivity of the particular surfaces. The high percentage presents the best possible circumstances for that material (for example a 99% reflectivity rating for mylar sheeting would be under ideal conditions - no creases, completely flat, no discoloration, etc).

The best way to determine how well your grow room walls reflect light would be to purchase a light meter and measure your light directly; then take an opaque board and hold it a few inches off one of your walls with the light meter below the board in such a fashion that the light reflects off the wall and onto the light meter. You can then compare the difference between the two and determine a percentage from those numbers, the closer the two numbers are, the better your wall reflects light. It is important that in both measurements, your light meter is the same distance from the light, otherwise your results will be skewed.

Also important to note is that radiant light energy refers to electromagnetic (EM) radiation with a wavelength between 400-700 nanometers (nm) and radiant heat energy correlates to EM radiation with a wavelength between 800-2000nm.

Listed below are some of the most commonly used materials used for grow room walls:

Foylon:


A more durable version of mylar, made of spun polyester fabric and reinforced with foil laminate. Foylon is resistant to most solutions, won't tear or fade, and can be wiped or washed clean.

A great solution for growers who are interested in long term use, and though it may be slightly more expensive than mylar, its durability will more than make up for its cost. It has the ability to reflect about 95% of the light and approximately 85% of the heat energy, so a good ventilation system should be used in conjunction with folyon.

A recommended method to attach Foylon to the walls would be using Velcro, as it makes taking it down for cleaning much easier nd reduces the risk of tearing, creasing or bending it. If this is used for your walls, making sure you get it flush with the wall with no pockets of air between it and the wall to prevent hotspots.

Mylar:


A highly reflective polyester film that comes in varying thickness, the most common being 1 and 2 mm thick. The 2mm thick mylar while not quite as durable as the foylon, is fairly rugged. The 1mm thick mylar tears fairly easily, so taking it down for cleaning is quite difficult without damaging it in the process. Both types of mylar are able to reflect approximately 92-97% reflective, giving it the potential to be more reflective than foylon, but because foylon is more easily cleaned without damaging it as well as it being harder to crease, foylon usually ends up being slightly more reflective. Important to note is that mylar reflects radiant heat energy just as well as foylon (around 85%), so proper ventilation is necessary if mylar is used in your grow room. Attaching this to walls can be done in a similar fashion as foylon, and the same caution should be used to avoid creating hotspots in your room. The 1mm thick mylar stands a fair chance of being creased or ripped in the process unfortunately, even if Velcro is used to attach to the walls.

C3 anti-detection film:

A specialized type of mylar that exhibits the same properties as the 2mm thick mylar, but in addition to reflecting approximately 92-97% of the light, it also is 90% infrared proof, making your grow room all but invisible to IR scanning. This can also be attached in the same manner as foylon or mylar, and the same caution should be used to avoid creating hotspots in your room.

Flat white paint:

Self explanatory; a great option for large grow rooms or for people who are interested in a low maintenance wall. Flat white paint has the ability to reflect between 75-85% of the light, and does not create hotspots. Adding a fungicide is recommended when painting.

Glossy and eggshell whites not reflect light as efficiently as flat white. Semi-gloss paint for example, only has the ability to reflect between 55-60% of the light. Also important to remember when using paint is that any smears or blemishes on the surface take away from how reflective the wall is so care should be taken to avoid marking or staining the walls. Titanium white paint is very reflective; however it is usually only used on reflectors due to its high cost.


White/Black plastic (also known as panda plastic or "poly"):

"Poly" is useful if you are setting up a temporary grow room or don’t want to damage the walls. Poly is easily cleaned.

The purpose of the black side is to not allow any light to pass through the plastic, which ensures your dark cycle remains dark. The white side is 75-90% reflective. Choose a 6 "mill" thickness of poly for maximum light blockage and duribility.

If this plastic is put too close to the light, you will obviously melt it so be careful!. Panda plastic does not create hotspots. Poly can be attached to the walls by using carpenter’s nails or using tape glue or similar means. This can be used as a cheap alternative to mylar if painting your grow room is out of the question.

Polystyrene Foam Sheeting (more commonly known as Styrofoam):

This is excellent for harsh environment growrooms (your attic for example), provided you have a good ventilation system and a way to keep the temperatures from rising too high (an a/c unit or similar) as it is an excellent insulator.

It is also a great material for use in a temporary setup or for use as a "travelling reflector" on a light mover, where weight is a concern. It is approximately 75-85% light reflective so it is comparable to using a flat white paint. Foam will not create hot spots. Rigid foam can be purchased in sheets, and can be used as a free standing wall or can be taped, glued or nailed to the wall, the last generally being the most successful method.

Emergency Blankets:


These are ultra thin polyester blankets that are sold in most camping stores and are constructed of a single layer of polyester film that is covered with a layer of vapor deposited aluminum.

It is not very effective at reflecting light because it is so thin. Holding it between you and a light source, many small holes are noticed at the intersections of creases and the entire blanket is translucent to begin with, this coupled with the many creases that are in it when you purchase it takes away a significant amount of it reflectivity. It is very easily creased as well which also detracts from its ability to reflect light. And while it is reflects nearly 90% of radiant heat energy, it is only able to reflect around 70% of the light.

The largest advantage of using this type of material is that it is very cheap and therefore easily replaced. Emergency blankets can create hotspots if not attached flush to the wall so it is important that no air gaps exist between it and your supporting wall. The easiest way to attach this is to use tape (Aluminum or metal tape is recommended), as it tears very easily once it is cut or punctured.

Aluminum Foil:

Aluminum foil is no more than 55% reflective - if used, make sure that the dull side is the one that is used to reflect the light. When it becomes creased its reflectivity is even lower (around 35%.) It is also very dangerous to use because it creates hotspots easily, is electrically conductive, and is a fire hazard when it is in close contact with HID lighting. Attaching this to walls is a pain and usually using aluminum tape or glue is the best way. This should only be used as a last resort, and even then its usefulness is questionable.

I'm not saying it isn't a popular myth! I've heard everyone repeat this as if it had actually happened to somebody at some point. What i'm saying is, I've never heard of these "Hotspots" actually happening to anybody's grow-op - have you?

I may not be the last word in explaining scientific phenomina, but it seems to me that a great deal of crinkled foil would be required and most of the "crinkles" would have to be focused on the exact same point (and that's with no air circulation waving things around). I'm saying that it is so highly unlikely that it would be hard to do if you wanted to do it on purpose. I may be wrong, but I still say "It's never happened to anybody - ever!".

There are lots of good reasons not to use aluminum foil as a reflective surface ( I just don't believe "Hotspots" is a legitimate one!) - and on top of that "Why take the chance - who needs hot spots?"

I know cats can totally get high from eating it. My cat got into some special brownies that were wrapped in foil when he was 6 months old and went from crazed hellion to a happy lethargic zombie that just sat, swayed and smiled for 24 whole hours. this same cat comes running over when I smoke and he loves me to blow it at him. he smiles and looks off into the distance. If i don't share he taps my foot like when the food dish is empty. He likes the good stuff because whenever i have lesser quality shit and blow that at him he makes a sour face and runs away haha. swear to god. I don't know if he just likes the smell or if he gets an effect from it but he definately likes it. Think about it though. Your lungs can't posibly filter out all the thc, and a cat lung is like the size of a bic lighter. We are roughly 30-40 times their size, so i imagine they require a MUCH smaller amount to get high, and if people can catch a contact, then why can't other mammels?

It happened to my friend. It was a little circle of crispy leaf, right where the foil reflected light.

Haven't any of you's guys watched the Trailer Park Boys before? Aluminum foil has to work if Ricky uses it! I remember using foil in a closet back many moons ago at college with a 430 son agro and 3 NL#5 and they were all monsters and nothing burned. Also we used it shiny side out, hung it using headliner glue in a spray can. Needless to say we just painted over the foil when we moved out, I dont think it ever came off! not that it's a good idea or anything, but it wont kill your crop either.

What type of lights was your friend using?
Was it just a "crispy leaf", or was it a "fried leaf" (really burned)?
How, in the world, did it keep from burning a hole, even deeper into the plant?
Did you, or your friend, actually see the reflected light concentrating itself into a single small area - could you feel the heat with your hand?
If the light was concentrated on that single area, did the rest of the grow suffer from lack of light?

Is it possible that something else could have caused the "crispy leaf"? I would really like to hear alot more details before I stand corrected!

1) Myth #1 - Minor light leaks cause hermies...
2) Myth #2 - Miracle grow doesnt work and will kill your cannabis
Light leaks causing hermies have to be a myth, walking to my grows at night and looking at all the light poles around my plants proved this to me. No hermies.

I've grown good buds from start to finish in Miracle Gro, maybe it lowers the quality and/or quantity, not sure but it was all great bud.

The real myth is that tin foil is something worth using... it's not! It only reflects about 10% of the light and it doesnt reflect it evenly either. Flat white paint is way more reflective then tin foil... even yellow paint is slightly more reflective if I remember correctly.

And...
Light leaks CAN and often DO cause hermies and at the very least it causes a range of hormonal problems within the plant that will effect your plant negatively...It also commonly slows growth and causes your crop to take longer to mature.... All of this is common knowledge easily found from a ton of reliable sources.

lol just to add to the animals can get high myth, my dog ate like a quarter of some regs and she was doing really strange shit. It was sad but really really funny at the same time.

So can animals get high? Probably. From blowing second hand smoke in their face? Probably not..

yea dogs can get high by eating it or by getting it blown in there face.... its not really cool to do though. Your lucky your dog didnt need its stomach pumped and a pricey visit to the vet, because that much weed could damage a small dogs insides seriously bad not to mention give it the worst acid trip of its life... not fun for your dog.

RE Orange Cordial Myth

Ingredients of a typical (if quite cheap) bottle of orange cordial;

Water, Orange Juice (10%), Citric Acid, Natural Flavouring, Sweeteners (Sodium, Saccharin, Aspartame), Preservatives (Potassium, Sorbate, Sodium Metabisulphate), Stabilisers (Carboxymethylcellulose, Acacia), Acidity Regulator (Sodium Citrate), Natural Colour (Beta-Carotene).

:-?

I wouldn't drink it, never mind feed it to such an expensive plant.
