does anyone know if theres any sleeves out there to turn normal florescent bulbs(4ft or 8 ft) into the proper color spectrum to promote growth or flowering ? ---maybe a cheap way to pick up fixtures people aren't wanting anymore and using crap bulds & yet still have the proper growth colors --then swap plastic tubes for the flowering stages

Light is a pretty complex issue. You can do an awful lot of research on light, and not know a fraction of what there is to know.

I would suggest reading up on Photosynthetically active radiation aka PAR, Light temperature. and luminous flux.

COB LED lights are what's happening now. And not terribly expensive. Last 50,000 hours.

yeah them LED are awesome ---and in my opinion fairly green-tech since they last so long it keeps a lotta other bulbs outta the trash ---its just around me I see the old type florescent fixtures in trashcans at jobsites all over the place --I bet I coulda picked up 250 of the 4 footer fixtures in the last few weeks if I wnted too----so I was thinking if people could find them free near them ---a colored sleeve dded to free lights makes for nice deal & ws wondering if they are on market anywhere --the sleeves that is

The answer is yes, they do make colored sleeves.....

fluorescent light bulb sleeves

But I don't think they will do what you're wanting them to do for grow lights.
There's a difference between bulbs that are designed to put out the specific wavelengths in the red and blue spectrum, and a filter over a regular florescent bulb..
IOW, you can change the visible color of the light to what you want, but that won't change the intensity.

that's so much bull**** ! ! ! grrr

fluorescent light bulb sleeves

I clicked that link it opens I look at a few links there (all still happy at this point ---UNTIL I notice the title of the search ---florescent light buld sleeves ---- this is where I get pissed off -----I TYPES EXACTLY THAT IN MY SEARCH & GOT NO VIABLE LINKS --hence why I started this link here in the first place ---ow wait yall it gets better ---I "convince" myself I musta typed something in wrong in the search ----so I type in exactly what it shows on that links search ---and I get nothing again --- I swear when it comes to the internet I couldn't find moisture if I was underwater sometimes

 

[chaossmurf]

by the way il be afk a bit looking at the link farmer provided ---thnx big time
im in no way mad at you --only upset at how bad my internet searching is ussualy

 

[farmrbrown]

LOL
I know what you mean.
Between my fat finger typing and constant "suggestions" from search engines, it's amazing that I ever find anything.

interesting little sidenote that I had pondered but didn't know how to word it in my original question about this -----
I contacted one of the manufactureres and they informed me that in order to adjust a red bulb sleeve or a blue one to "A certain color" it all changes between diferent bulb manufacturers and such --because diferent bulb manufacturers use diferent glasses ,thicknesses, inside chemicals, electrical parts & so many other thngs --that theres no way to say their sleeve would provide a certain light ---but I was free to buy diferent ones and return any ones that didn't provide the color spectrum I was aiming at for just the shipping charges
so im guessing this was a waste of all our time --- other than at least my idea that diferent bulbs would provide diferent spectrums even with the same exact sleeve applied to each of them BLAH

Smurf - when I worked in Special Ed. we would lay different colored plastic overhead sheets (that were used with the old overhead projectors at school) over the white pages of a text book for kids with dyslexia that a different light spectrum helped (we had the flourescent bulbs in the ceiling lights at school) them to read better. Anyway, I bet you can still get those plastic overhead sheets at Walmart or a store like Staples and then you could tape them over the bottom of the light holder for the light to shine thru onto your plants..... You CAN buy the "natural" light flourescent bulbs though but they cost a little more than normal ones. A friend of mine used to buy them for her classroom because it helped with the kids behavior to have a more natural lighting.

 

[chaossmurf]

yeah id be way wway better just buying the natural light bulbs & even the newer pricier ones than my original idea of colored sleeves --just because id have to keep trying bulb&sleeve combos --untili found the light spectrum I was looking for ---isn't worth all that time and expence to save a few bucks on fre elight fixtures from construction projects

That's too cool. You're the only person other than my mom that I ever heard talk about that. She was a special ed teacher most of her life. She helped one of her students transition back to the regular classroom after only a year when she discovered the same thing. The florescent lights give off a wave length that some people are hypersensitive to, causing headaches and behavior problems with learning. After finding that a yellow filter was what allowed him to see without headaches, he got yellow tinted glasses and was "cured" of his learning "disability".
KUDOS TO GOOD TEACHERS EVERYWHERE!

Sorry for the thread hijack, but I love it when someone gets the help they need.
