They are sometimes used, however aren't really used since metal halide and high pressure sodium are much better. Get one of those or flourescent (flourescent doesn't perform as well.)
so is it bad, how about that and a fluerecent at the same time, i have two 4 FT. Fluerecents.
Lamp Type ....................Watts.... Lumens/bulb ....Total efficiency
Fluorescent Bulb ..............40................3000........... 30k lumens
Mercury Vapor................ 175.............. 8000 ............20k lumens
Metal Halide................... 400 ..............36000 ...........36k lumens
High P. Sodium ................400.............. 45000........... 45k lumens
Notice the Mercury Vapor lamps are less efficient than the fluorescent (FL), and can not be positioned as close to the plants, so the plants will not be able to use as much of the MV light. The light distribution is not as good either. MV lamps simply are not suitable for indoor gardening.
Good luck and have a good grow!:thumbsup:
well it made the room a looot warmer way faster. and its a closet, but its warm enough. the light just makes it 5-7' warmer if i leave it on
No one has said anything about LPS. MV arnt all that good, no one really uses them. Get a HPS, you'll get alot better yeild wise.
they do make phosphor coated mercury vapor bulbs, raises the color from 5900k to 4000k (still not ideal, but quite a bit more red).
you might look in to a cfl conversion replacement bulb
good luck
envirolites are a good cfl bulb im using them and they are quite nifty really
they come in 2 sizes and 2 colours
125w and 200w
blue spectrum for vegging
and red spectrum for flowering
and as an added bonus they are self ballasted
check this link out www.envirolites.co.uk
cheers all :)
switch the mercury bulb for a halide bulb of same wattageQuote:
