lamps and lighting
    #22499587 - 11/09/15 09:30 AM (8 years, 2 months ago)

so i'm thinking of starting some ethnos again after a long time,
and i am wondering what's new in the world of artificial lighting.

in the last decade people apparently figured out that a 6500k bulb
is best for mushrooms, is there any plant that happens to like this colour?

what types of lamps and light colours are you guys using, and what are you using them on?

I use a 4 X 1026W, 5800K, fusion lamp.  For ALL my adult cacti, which are mostly Mexican desert cacti.
For seed raising I use a pair of 20W, 6000K fluoros.  But I am probably old-fashioned - the young thrusters like LEDs I believe.

He is referring to the sun.

As far as indoor lighting, I use a mixture of 6500k CFLs and tubes. Anything I grow indoors (other than my usual houseplants, of course) gets put under these. Everything from salvia, to cacti, to cacti seedlings, caapi, psychotria, everything.

I also use the same lights for starting herbs and veggies over the winter and spring. :thumbup:

I just don't have the budget to jump into any larger and pricier lighting systems...

sunlight isn't much of an option for me for certain plants, as we
just don't get enough here in holland. (currently getting 8 hours a day or so)

anybody ever try to grow weed with 6500k bulbs?

I think there is actually someone on the forums doing this right now.... I may be wrong though...
I don't grow it myself so IDK really.

Fine for veg.  I haven't tried in flowering.

A cloudy sky is brighter than any indoor light.  And a higher colour temperature.  If you do a Google you can compare lux readings for different sky conditions and different lights.
And currently ALL of us in the Northern Hemisphere are getting less than 12 hours daylight.

Lights never have the exact color of the sun but you can get 90% there with good lighting.  If you live far enough north then the light intensity on a cloudy day in winter is far, far lower than a good grow light. I don't think you comprehend how dark it gets in the winter once you reach a certain latitude and what kind of gloom certain areas receive.  Where I live, the sun doesn't even shine bright enough to give you your daily dose of vitamin D in the winter and people have to take supplements.  I've actually been doing a lot better with that since I got my growlights because on the darkest day I can go look at my cacti and feel some near sunshine coming off that light.  It's a real life saver.  There are even local companies that specialize in putting halogen, xenon and other high intensity lighting into people's houses so that they don't blow their brains out from SAD in the winter. :lol: 

@OP, what kind of plants are you wanting to grow?  I have a T5 flourescent and it is good for b.caapi, pereskiopsis and globular cacti, although trichocereus can't get very thick under it and while I don't grow weed I don't think it would cut it for that either.  It really depends on what you want to grow, how much you want to spend and what kind of heat/electrical output you want to deal with.

for weed i was planning a windowsil grow with some autoflowering lowryder or something like that.
but i am considering setting up something with cfl lights or maybe LED lights.
but i think i will take that question to the weed forums.

i plan to start a bunch of cacti from seed, as the local cactus club sells seeds donated by
members for ridiculously low prices. and i want to get my hands on a salvia cutting.
beyond that i'm considering getting back into carnivorous plants.

Yeah, the weed guys are the ones to ask about weed. :lol: I like my 4' 4 tube T5, my plants probably won't grow super thick in diameter but for most ornamental, globular cacti and other tropical ethonbotanicals it is an affordable and well rounded option, doesn't give off too much heat and doesn't suck electricity.  I think I paid around $140.

Fluoros will work for weed, but the buds won't be very dense and growth will be slower. I'm still not a fan of LED's. A buddy of mine worked up a prototype of an LED which looks much, much better than anything on the market today using large white light LED's, instead of the little multi-colored things that cost an arm and a leg.

Look into a Ceramic Metal Halide bulb to more represent a full sun spectrum. They run on magnetic HPS ballasts. It would be a good supplement for a window sill, as it won't look like a parking lot in your window. I did a complete grow with a 400w CMH and was pleased with the results. But nothing tops an HPS.

Really incorrect info here.  A cloudy day is probably going to be (far) under 10,000 FC, which can easily be beat by some strong lights.

That one aimed at me??  LOL, I lived in Scotland for 8 years - and a cloudy sky there still has a ´standard´ light intensity of 5,000 lux (1 lux = 1 lumen m-2) - but this is very variable and an overcast sky can reach 35,000 lux in high summer.  Clear sunny skies can produce 100,000 lux.

What is not widely appreciated is how very, very much lower are light levels we use indoors.  A brightly lit office has about 400 lux.  A warehouse aisle about 100 lux.  To read requires just 50 lux.  This is not widely appreciated because the human eye is totally useless for judging differences of light intensity.

A 20W T5 or T8 fluorescent tube, commonly used to raise seedlings, has a light ouput of 1,000 lumens.  You would need serried ranks of these to illuminate a room to the brightness of an overcast sky. 

Artificial lighting just cannot compare to the intensity of natural light - if you want to avoid etiolation give your plants natural light. Put them in a cold frame or greenhouse - I did that when I grew in the UK - had to use a paraffin heater in winter to keep the frost off.

Of course people use artificial lights for weed - there is only ONE reason for this - weed is ILLEGAL and you have to keep it out of sight.  The stuff grows far better under God´s sun.

I would be a bit more impressed with some actual data - rather than the expression some strong lights.  Also I think all lamp suppliers are now fully converted to SI units.

(I still use FC so you'll have to convert that to lux if you so desire)
I have a light meter, I know that cloudy light is weaker than optimal for budding.  It doesn't matter what kind of light or what kind of bulb or what kind of equipment were talking about, if you reach 10k you got the job done.  Cloudy might get you by for veg... but decent lighting can blow away cloudy light.

Weed WILL NOT grow better in cloudy light, than the guy who has the indoor set-up.  This is so basic.
