If you get the desired results you should go into business by supplying the plant world with the coloured cloths/sheets lol then when you make a million remember me for suggesting it, I'd be happy to get a 10% cut in the post lol

Thanks for the encouragement Tracy & Phil.Am sure to split the spoils of this patent tent with you folks, if it works! :)

muy interesante

Muchas gracias

I do not mean to rain on this parade but this basically just shades the plants. They will get less light instead of more because the fabric does not emit blue and red light wavelengths in themselves, it just screens out the sun. They are better off fully exposed, absorbing the light at wavelengths they can use.

Artificial light that emits red and blue light is useful indoors though, since there is no other source of light for plants to use and they have to be provided artificially. Grow lights are made in the red and blue spectrum in order to save energy by directly providing plant-usable wavelengths instead of generating white light that plants will then have to photosynthetically separate into what they can use.

Thanks for your insights Pagan, as you know I recently changed the soil around 01 Oct 15 to half coco coir +half manure for all these which I had earlier planted in gravel with little soil only.

Now I don't really know whether the soil change or the blue light filtered through this plastic shade is working but the plants seem much better off under the shade coz they were'nt putting out new leaves then, but have started that in the last one week.

Its always sunny on this south balcony so they were in the sun since 01 oct till 13th oct but the response to the blue shade has been good in my opinion.A few more days will tell.

The blue red grow lights are available here too but I don't have that much space indoors to house them in a separate room in my apartment so I resorted to filtering the available light to kick start these.

A pic below will show the changes
