Lightting Problems
    #10665215 - 07/12/09 07:34 PM (14 years, 8 months ago)

Ok i used to be able to just take my humidification tub outside and leave it till the sun went down for my source of 12h light, anywho i just got some new nabiers and i just cant put out my monotubs and be worry free.

So ive decided to move everything inside thing is i never had luck with ligts where ill never get pins but im guessing that's cause ive tried to do it 12H on 12H Off, an nothing so idk if its the lights im useing or what?


This is what ive been useing, what am i doing wrong?

You should be using light in the 7500k color temperature range. These are usually marked as "Daylight" or something similar. I got a small 18" fluorescent hood and a daylight lamp for under $15 at Wal-Mart.

Oh I also Just Bought Some Rope Light seeing as in some Teks it seems to work.
dose it matter what trype of rope light it is?
and if i leave a light on for 24/h will that cause pins?

Light is the least important pinning trigger. More importantly you need plenty of fresh air exchange and evaporation.

The ideal range is 5000-6500K.  Most fluorescents are around 4100K so make sure you find one that's marketed as daylight or has the right kelvin spec on it.

Light is a secondary pinning trigger, but using the proper light source has really helped improve pinset formation for me.  It usually takes a substrate 7-10 days to colonize fully and another 5-7 days to see pins.  How long are you waiting?

no offense but are you guys serious? leaving the bins or whatever out in a room where there is light coming in, or on, is fine to initiate pinning....... no purchasing of any lights is necessary to grow caps unless you are in an area like alaska where they dont get sunlight for 6 months or something crazy like a volcano erputs and the ash blocks out the sunlight for an indefinate amount of timeeeeeee?

Sure, if you're happy with a mediocre pinset.  If you want a great pinset, you'll provide bright daylight or a fluorescent or LED light in the correct spectrum.

I was going by RR's notes here in which he repeatedly mentions 7500k, not 5000k-6500k.

6500K seems to be about ideal.  Where did you see 7500K?  I could have made a typo, but it would be strange to make it repeatedly.

Here: Although now that I look, you also recommend slightly lower than 7500k from time to time as well. Of course who knows when you made these posts since they were all collected into one document with no links, timestamps, and many are out of context.

http://www.shroomery.org/forums/showflat.php/Number/8468474#8468474

"*The Kelvin scale refers to the color temperature of the light. Briefly stated, if you took a piece of white paper and looked at it under 2,000K such as you'd get from hps, it would look yellow. If you looked at it under 5,000K fluorescent tubes such as you'd find in an office or school classroom, it would look white. If you look at it under 7,500K fluorescent, it would have a blue tint to it. That's what is meant by 'blue' light. You can pick up an inexpensive fluorescent fixture and 7500K fluorescent tubes fairly cheaply at your local hardware store."


and here, although to be fair here you said 5000-7500 and not 7500.

You can't argue that light makes a big difference with growers that are happy with crappy pinsets. However, if you want the best pinset and growth you can get, and then use bright light with a color temperature of 5,000 Kelvin to 7500 Kelvin. Of course, there's other parameters that are just as important, if not more important than light. Failure to pay attention to ALL the pinning triggers is like trying to win the Indy 500 with a clogged up air filter or dirty spark plugs.

*5100K is fine. I think 6,500K to 7,500K is better, but when you compare to incandescent bulbs which burn at 3,000K, they're way better. Definitely, you don't want red. You also don't want any sort of colored cover over the bulb, and that includes blue.

I had some awesome pinsets when using the same room for hydro and mushrooms with a 400 watt metal halide, which only burns at 4,000 Kelvin.  I think it makes up in intensity what it lacks in color spectrum.  If it's already there, use it.

LED rope lights can now be bought for nearly any color temp you want.  I recently purchased 1,000 feet of daylight LED rope lights for my new underground mushroom farm.  An added benefit besides low wattage is it's waterproof so can be direct sprayed with water.

That is the color temperature of the light (a bit of an abstract concept if you aren't scientifically inclined but the Wiki is pretty good) but long story short 7500K stands for 7500 Kelvin.

If you're referring to the rope light that they sell at Wal-Mart, it is not in the 5000-7500 range (although it doesn't say anything on the packaging, you can see that it's really a yellowish-white, indicating that it's probably more in the <4000 range). If you're going to go with a rope light for sure, get one online. If you want something quick and cheap but also effective for a couple grows, buy a 2-foot fluorescent fixture ($5-$8) and a daylight bulb ($3-$6) and a wall timer if you need one.

So i just got back from Walmart and nothing, where would you suggest on finding this sort of light?

Hmm, I found one at Wal-Mart for $8 but I also saw similar lights at Menards. Most hardware stores should have something that'll work, just make sure you don't buy a ceiling fixture (you'd have to buy a plug adapter).

Wal-Mart should have what you need. Last time I went, they had at least 20 different bulbs that would work.

For my setup, I picked up one of the GE 12" Flourescent Utility lights that runs on batteries that come with adhesive strips. I have a really deep Sterilite tub that's opaque and used the adhesive strips to mount the light to the lid. Stays in my closet, produces very little heat, and is very inconspicuous.

Whichever one you get though, the lightbulb itself will have a model number, and usually if it doesn't say "daylight" somewhere on the packaging, if the model number ends in D, it's a 6500K bulb. Stay away from ones ending in WW and CW
