RED Mylar for flowering???

[tat2ue]

Has anyone had any experiance with red mylar??? I went ahead and ordered some from my Hydro shop and picked it up yesterday. I have two 8' flood tables set up for SOG and was planning to enclose one table with the red mylar and put in a new batch of clones to flower tomorrow. The other tables is in it 5th week of flowering with the standard silver mylar so I can do a side by side comparison. I figured the the red would intensify the red/orange spectrum of my 600w HPS in the flower room. But if anyone has had a chance to use the red mylar, what is your feed back??

I would think anything besides white would absorb more light. Pretty sure its normally white because that reflects the most. I've never even heard of red mylar, only black/white. So it will be interesting to follow this.

looks like a "whore house" in there....i want to see how this goes

I guess you could call it a whore house....there is 80 good looking females behind the red curtain waiting to please me....lol

ha ha ha sounds good!

I would take the whore house as a complement. I don't think anything could go wrong as red is the way to go :]


"I had a friend who planted several rows of tomatoes out on his land in the country. Lots of space and lots of tomatoes so it wasn't just a fluke...the tomato plants that had red (plastic?) laid under them grew at least twice as big as the other tomatoes! No kidding. Thanks for the reminder. I'll put it under my tomatoes this year too.
P.S. I am doing "Straw Bale Gardening first time this year. I 'm excited about it since it will be much easier to harvest and keep watered. I wish you well on your gardening."


just read this.... so... I'm going to try this also

looks promising i like radical thinking and hoes

to the person posting about red plastic underneath tomatoes.....red plastic? seriously? was it red mylar? was there normal full spectrum mylar tested too?

honestly to me, this seems like complete snakeoil

if the mylar reflects back red, it is therefore filtering the other spectrums. Why not have the full spectrum reflected? Sir, you should get a refund from those hydro store numbnuts.

The will do more refraction and absorption of light than reflection. Seems like a waste of time and money to me.

Red mylar does not intensify anything. Regular full chrome looking mylar is what you want. How people got into this blue light vs red light debate is beyond me. perhaps people thought the sun puts out more red light in the fall than what it does in the spring. This is STUPID!! Its the SUN, it doesn't change its light output to suit our growing seasons, People might think it looks more red but that's because the leaves on the trees are turning red so that light is more predominately reflected. It has shit to do with the sun other than its lower in the sky causing temps to fall which then causes leaves to turn gold and red and orange.

The suns 'real' kelvin temperature is somewhere around 5,800 degrees kelvin, but because the sun is not a perfect 'black body' (the standard for calculating kelvin temperatures of light) its adjusted kelvin temperature is somewhere around 6,400 degrees kelvin.

6,400 degrees kelvin is predominantly 'bluish-white' light and this is the best kind of light and kelvin temperature for vegetative growth - primarily because in nature the time of year Cannabis is in vegetative growth is during the long hot days of summer where the suns daylength is the longest and receives the most 6,400k light. The reasons it changes for flowering is again because of the predominance of the kind of light found from the sun when Cannabis enters it's floral stage - usually at the start of Autumn or Fall when the days get shorter and the nights longer thus reducing down the daylength significantly. Sunrise and Sunset account for almost 50% of the suns light during the short days of Autumn/Fall and sunrise and sunset are made up of almost entirely red spectrum light due to the angle of the suns rays hitting the earths surface. Therefore as sunrise and sunset account for almost 50% of the sun total light output at that time of year it necessarily follows that 50% of that light will be entirely in the red end of the visible spectrum - hence the 2,700k colour temperature being favoured for flowering. In reality a mixture of red and blue light is required in flowering due to the other 50% of the spectrum being more blue in colour.





You still can argue, but like I said. it was tested and shown that the 3 plants out of the bunch with red reflectors under it were significantly bigger than the others next to it. I guess that means nothing since the only difference was the red.
and...."IT DOESN"T HURT TO TRY" If it doesn't work like you say oh well, it would be like him not doing it since it will grow the god damn same

I agree with this.

If anything it will absorb more light taking away what should have gone to the plant.

obviously won't intensify as much, but flowering loves red. and it intensifies more than dirt. and the sun does change light output. as I posted above

Hi. I think this is where the idea for the red mylar comes from. http://etmd.nal.usda.gov/bitstream/10113/17874/1/IND89030828.pdf
who knows, it might be great? keep us posted- I'm curious.
I was actually planning on ordering this for my garden this year... worth a shot. http://www.leevalley.com/US/garden/page.aspx?p=10532&cat=2,2300,33272

uh ohhh. good stuff. of course people can argue it's just advertising to sell a product. but it's also factual.... as it was done in plenty studies. I'm still probably going to lose the debate with all the science and facts put in this guys face

The sun does not change itself. But light spectrums and intensities do differ morning, noon, evening and season too season by how it is diffused while passing through the atmosphere at different angles. And the red mylar is the new fad in growing Thanks OP for testing and sharing. +rep From what I have read so far it may have promise........

Well I am in a position to give it a side by side test of red mylar -vs- chrome mylar. I have two 3 x 8 ebb and flow tables in my flower room. One table has been in flower for almost five weeks using the chrome mylar and I just harvested the other table a few days ago and I'm in the process of getting it ready to put in 80 rooted clones to flower. So I am going to use the red mylar around this table for the flowering stage and see if there is any difference in yields between the two. Everything else will be the same in respect to plant strains and genetics, lights, nutes,temps,humidity,CO2 enrichment. The only difference will be the red mylar and in 7-8 weeks I'll know for sure. But if I don't try it, I'll never know.

Perfect. Can't hurt to try. Let us know. +rep

Isn't it more likely that the tomato comparison was between plants with a reflective underlay vs plants with plain dirt or dark underlay? That would really explain The issue. Extra light bouncing back up vs a plant with no extra light bouncing.


I'm on the boat that the Mylar is not going to produce any red light therefore it is simply absorbing the rest of the spectrum. I'm no scientist though
