Light
    #7772613 - 12/18/07 01:40 AM (16 years, 3 months ago)

Hey everyone, this is my first post here on this wonderful forum. :laugh:
I've been reading for a while before I signed up. I was wondering though, is a 25w lightbulb too hot to use in my fruiting chamber? Right now I've got my cakes under a 3.5w (I think) light and I'm concerned that it's too weak. Is light even necessary?
thanks, Sam

Hi, welcome to the forum!
Mushrooms need some light to initiate pinning. In other words, a light is not really necessary, unless you're growing in a completely dark environment.
25 Watt is too much imho. However, I would measure the temp around the cakes. It shouldn't be higher than 26-27 C.
There is another disadvantage of lights as well: the heat of the light causes the humidity to decrease. So if you use a light, I would use a 8 Watt fluorescent light or so. Do not use incandescent bulbs since they produce too much heat a too little light.

Those new compact florescent bulbs stay cool. A 15watt florescent would be equivalent to around 75watt incandescent bulb, in brightness.

I'm not sure what other wattages are available with compact florescents.

An incandescent bulb might heat up a little bit much, plus it doesnt provide light in the right colour temp. A "daylight" compact fluerescent will provide much better results than just ordinary bulbs. (plus they last much longer)

Only needing a small amount of light is not quite true, while mushrooms dont use light to grow, the light must be strong enough the penetrate the surface of your casing layer and reach the surface of the myc. So a nice bright light is needed

25w CFL won't heat up to much and give off lots of light (make sure it is the right kind of light)

If you are not sure, test it in an empty FC for a day first

If your unsure, a cpl light in the right temp will give of a cold blue tint (not a blue light but cold looking)

No light should be inside the terrarium. The lights should be next to or above the fruiting chamber.

Thanks for the warm welcome! I'm not using a casing layer so I don't think it needs to be a super powerful bulb, am I right? The light is outside of the transparent fruiting box. I wouldn't really call it a terrarium lol
I'm not really sure what a CFL or a CPL light is...

also I'm really diggin' that avatar of yours, RogerRabbit lol

Probably because The high humidity will cause your light to burnout and even become a fire Hazard.

I use an aquarium with a fluorescent light built in the lid. Works well! I think what RR means is that you shouldn't put the light too close to the cakes. I would dry them out because of the heat they produce. Especially incandescent bulbs produce a lot of heat.
Also, throwing a light in the FC could be dangerous (short-circuit) if you do not prevent the light from getting in touch with water.

CFL = Compact Fluorescent Light. Those energy saving bulbs. As the light that the shrooms detect is in the 6000k and over range, a normal incandescent (filament) bulb will not work. You need or a fluorescent tube or a CFL that emits light in that spectrum.
