First attempt at a 24-hour "Martian Method"

Sal..... Also could I put some kind of blue filter like (colored cellophane) on my glass lens and filter out blue light from a 400w bulb. I want to use this life light 4k CMH bulb from the pic below. I like the amount of red and far red in the bulbs spectrum but I don't like the amount of blue. Could I filter that out somehow. I know the tempered glass I'm using now filters out some of the blue but more then likely I want more of the blue filtered out of this bulb for flowering and the martin method. Thanks again for your time.

We've tackled filtration on both HID and Floros, and HID (HIGH INTENSITY DISCHARGE) will fry most filters other than glass or quartz.

If your filter is gonna give and it's not glass, it will distort (melt and shrink) before it discolors (burns). So if you're gonna go there, watch out for ripples and shape changes on what should be a nice flat surface. (I did a Blue gel filter across the glass shield of a 400 to 1000W air cooled HID hood, w/ only a 200 Watt MH bulb in it, still to much heat and fried the gel filter.)

If you gonna give and it's glass, THEY DO SHATTER and they usually do it soon if you are overloading them. (I used two Blue filter glass sheets on a 500W Incandescent source and shatterred the first one in under two minutes and the second one in under another minute due to concentrated leaks through the breaks in the first one).

For DAY lighting with artificial light, use unfilterred light since the plants can use it. And at night, it's time to weigh the benefits of filterring against the light losses and other factors.

Also without knowing the Spectral Transmission Distribution (STD) of the filter, you couldn't be sure what spectrum was coming OUT of it, which may not be what you want at all. Most filters tend to remove light across the spectrum, not just in the range you want to eliminate, and may remove much of the light you would rather keep.

Be Safe.

Take Care, Sal.
