i was smoking a spliff with my mate and he told me he got told that when transplanting into new soil u should break the root ball up so " the roots can spread into the new soil more easily " i told him was bullshit, id never do that n would more than likely course more stress than good
worst thing is he did it with a greenhouse seeds bubba kush i gave him in a party cup

What is a PPM ??

A common Old Wives Tale (there are others, believe me) is that Aluminium foil used as a reflector somehow causes hotspots on your plants. Total BS, people read it and then just repeat it, nobody has experienced it because it DOESN´T HAPPEN !!!
Take any series of calculus courses and you will actually learn why you are wrong. It's all based on parabolic curves, and their ability to concentrate light energy. This is actually the foundation of the invention of the telescope.... The chances of creating this condition accidentally are small, but that's not to say it's an 'old wives tale'. It's a mathematical fact, and the foundation for many applications you use every day (for instance if you are using a reflector on your light, chances are it is a parabolic design who's shape is based on the math behind focus points of parabolas) :)

i dunno... my friend had a shitty ghetto grobox, wrinkled tinfoil around the walls ( that shit is almost impossible to keep completely flat) and his plant looked burnt, asif he had split nutrient water on the leaves and the light created a magnifying glass effect, but he was using cfls and was feeding via a tray at the bottom, and then i looked at the glow spots on the tinfoil... it kinda clicked so im sure it is possible, dont hate the player hate the game

This sounds very much like mythbusters tbh, sure in a certain application it is plausible, but only when they rent a minigun. I have not found any horror stories of tin foil hotspots yet, searching around it seems that people being told to be cautious of hotspots, well they'd been using tin foil for years prior to learning about them. I don't doubt that it might be possible, but i wouldn't have thought it would be an occurence under standard conditions, i mean foil is designed to dissipate heat to minimize hotspots. I just don't really care less about the "issue" until someone shows me lots of pictures of hotspots on a regular basis to make me worried, the only thing that would put me off using foil as a reflective material would be the reflective quality.

Question, qhy does mylar not create hotspots? I mean mine has to be the worst applied mylar to exist, it waves around, is crinkled and creased, causes spears of light to dance around when the fan is on etc, no hotspots from that, is it the light from the light or the heat from the light that is the apparent issue with foil (just feel like learning something new tbh :D)

pruning your fruit trees and taking off foliage always and will produce bigger fruits and veggies as will a MJ plant.
Considering the buds need fan leaves to grow, explain how removing the fan leaves will increase the yield? certianly it might allow more light down to the lower fan leaves, but it will be a seesaw effect in that you are no longer getting as much light and energy to the top of the plant.

quite a few people have told me that miracle grow is the best soil there is. i call it b/s lol
it is if used correctly. if you start a plant off as a seedling in MG soil thats bad. but transplanting after a plant is 3 or 4 weeks old is just fine and they will trive like no 2morrow

im am only talking the leafs that come strait off the main stalk. most of the time they are the ones with the purple stem. cutting any more then that and yes your just hurting your plant, and yeilds

I would agree with you 100%. It requires a very particular situation that is very unlikely to arise by accident. I like to think of it as any other time you are playing the odds. When you fly, there is a chance your plane is going to crash, but the odds are slim, and you weigh that risk and decide to fly anyway. Foil dissipates heat because it is not a good reflective surface, so more light energy is absorbed in the form of heat. It is also a good conductor, so that heat easily radiates through the surface. It does still reflect though. Another way to put it in perspective is to think of how much care must be taken to grind a mirror perfectly for use in a telescope, it is unlikely you will create this situation accidentally, however knowing this is a far cry from just blatantly saying that it's a myth with no foundation (which was what I felt the original post I was responding to was saying). You could also create a perfect parabolic surface to focus your light on a .1"^3 area (or smaller if you like), but if you're light source isn't strong enough it still might not burn a plant...

I haven't used mylar extensively, but the stuff I have used had an insulation layer, or was mounted on a rigid surface, so the chances of creating angular reflection is basically nil (you would have to purposefully shape the stuff I was using to create such an effect, unlike tin-foil which easily forms angles and curves). The concept holds though, and if positioned in the right shape, any reflective surface has the ability to concentrate light energy to a small area and create higher levels of heat.

My post was certainly not to say that using tin-foil will burn your plants. I simply get tired of hearing people stating their experience as absolute fact when they don't really understand the topic they are commenting on. Though less than ideal, I by no means think tin-foil is an evil thing, but if you understand how things work you know how to ensure you don't have problems, so I truly believe that educating people about what conditions *could* lead to tin-foil causing burn is much better than fallaciously saying this is a myth.

Thankyou for your opinion, i was getting fed up with people simply stating that things are dumb or false without offering any reasoning beyond a loud mouth, i always figure i might as well learn about soething if i'm not too sure on it.

With the mylar i picked up, it is very much like that silver wrapping foil for presents, really flappy and loud, also a pain to handle, silver rap get's all over yours hands (or at least it did with my variety) and as a result of me being, well, me, it is not as flush to the wall as one would like :lol:

I;'d have thought that a smooth curve in my mylar, being 80-90% reflective and such, would cause a heck of a lot more chance of a hotspot due to the parabolic curve thingymajig, than a crease in foil (crease will not concentrate light as well as a curve i'd have thought) yet myalr and hotspots are never mentioned together. I'm interested to get to the bottom of this. WIt that in mind it also would stand to reason that foil would be safer because it can't curve uniformly in the way mylar can (the mylar was delivered as a roll of it, so it naturally tries to roll itself up, curveyyy)
