Lighting question
#18743240 - 08/22/13 04:32 PM (10 years, 5 months ago) |
|

Does it matter how powerful of a light is used? My friend has an insulated shed that he wants to use for growing. It has no power source and a generator isn't a viable option due to the attention it would draw. So he's trying to put together a plan for lighting. If he was to get a car battery and a power inverter, a lower wattage light bulb(such as 13w) would help save battery life and he would only have to recharge the battery every few days as opposed to using a 40 watt fixture and recharging every single day. Is a 13w bulb enough light bulb for a room with say 10 monotubs?

Can you run an extension cable from house to shed?
As per 1 13w bulb for 10 monotubs.. its doable but id say 3-4

The extension cable can't be done as it would also draw too much attention

does the shed have a window? just use natural light if you can.

Something like this. Use rechargeable batteries. You have to turn it on and off anyways. So just recharge them each time you're on dark time.
Battery operated light

He's thinking about going with a 12 volt battery(110 aH) and a 13 watt CFL rated at 12 volts. That should last quite a while

It doesn't need to last a while. Unless the light is on a timer, it has to be turned off and on anyways by hand every 12 hours. Small light, small batteries, easy to conceal, easy to recharge batteries. Personally, I would tap into an existing circuit on the house (or just make a new one) and bury a line all the way out to the shed. It's rather easy.

Actually, 2 hours should be plenty. LEDs maybe a better option. Less power consumption. Plus, I'm too paranoid about exposing my grows to mercury from a broken CFL bulb to use the CFLs.

I wonder where you get your info from...actually I don't 
Don't break your CFL bulbs, then you don't have to worry about mercury (which will affect more than your grow).
Not only that, it has been long proven that you need to break many CFLs to ever pose a risk.

Don't use a car battery. Get your hands on a marine battery. They're designed for deep-cycling. Car batteries will fail after just a handful of deep cycles. If you're in the US, Advance Auto Parts seems to always have some kind of discount deal going on that can help you get a marine battery for cheap.
LED lighting might be better than fluorescent lighting, too. This strip of LEDs will run directly off a 12-volt battery. The whole strip will draw more power than that CFL, but you can cut it shorter. Even if you cut it down, you should get more light out of it than with the equivalent power put into CFLs. And you can lay the strips directly over the individual tubs so more of the light shines onto your grow.
Either way, I don't think you can expect a charge to last more than a week or so, even if you're only running the lights for half the day.

2 hours will leave you with insufficient lighting. A 12/12 schedule is recommended for beginners, but can be adjusted slightly.

A 12/12 schedule is best. What does skill level have to do with it?

Some people prefer more light during pinning time and more darkness during fruiting time. But, for a beginner a strict 12/12 cycle is ideal as not to change things too much without knowing whether it's a help or it hinders growth.

It's kind of hard to argue with Pennsylvania University.
http://mushroominfo.com/growing-mushrooms/six-steps-to-mushroom-farming/
"A question frequently arises concerning the need for illumination while the mushrooms grow. Mushrooms do not require light to grow, only green plants require light for photosynthesis. Growing rooms can be illuminated to facilitate harvesting or cropping practices, but it is more common for workers or mushroom farmers to be furnished with minerâs lamps rather than illuminating an entire room."

Here is more current lighting info...
http://www.mushroomvideos.com/Terrarium-Tek
""Lighting Requirements of Mushrooms
Some mushrooms, such as the Agaricus species commonly found in grocery stores require no light at all. However, those commonly grown by hobbyists, such as Pleurotus ostreatus (Oyster Mushrooms), Lentinus enodes (Shiitake), Psilocybe cubensis, a hallucinogenic mushroom, and Hericium erinaceus (Lion's Mane) all require light to produce abundant, normal sized fruits. Experience has taught us that the light best suited for primordia formation and the development of fruitbodies is bright light with a color temperature of 5,000 Kelvin to 7,000 Kelvin. Fortunately, this type of light is easily obtainable at your local home improvement center in the form of fluorescent fixtures. For a small terrarium as described in this chapter, a single CFL (compact fluorescent) that screws into a standard light bulb socket will work very well. These can often be found in grocery and drug stores in every neighborhood. 15 watt CFLs will do the job well, but the package will probably have a large 60 stamped on it, indicating they produce light "equivalent" to a 60 watt incandescent light bulb. They're referring to lumens of output, not the frequency. Incandescent light bulbs are the worst possible choice for growing mushrooms, since they emit a 'red' light in the 3,000 Kelvin color temperature range.
The higher the color temperature, expressed in Kelvin, the closer to the 'blue' end of the spectrum the emitted light is. The lower the color temperature the 'redder' the light is. If you have a choice of fluorescent lamps, purchase those labeled 'daylight' since these have a somewhat higher color temperature than cool white. Daylight, sometimes called 'natural daylight' fluorescent tubes generally emit light in the 6,500 Kelvin range, while cool white fluorescent emits light at around 5,000 Kelvin. If you have several terrariums stacked or otherwise near each other, you can use larger 2 to 4 tube fluorescent fixtures. These come in 48" and 96" lengths. Place the fluorescent lamps as close as you can get them to your terrariums without causing excessive heating. Species such as Shiitake and Oyster mushrooms prefer to fruit at temperatures in the upper 50's to mid 60's Fahrenheit (15C to 20C), while Psilocybe cubensis prefers to fruit at a temperature in the mid 70s to about 80 Fahrenheit (23C to 27C) Most mushroom species don't mind a slightly warmer temperature during daytime than at night, so if your grow room is a bit colder than the temperature ranges given above, a little warming from your lights during the daytime won't hurt at all, provided you don't let the air in your terrarium get too dry. For cakes, try to keep the humidity above 95%. Cased substrates are a bit more forgiving, but still try to keep your humidity above 90%. 12 hours on, 12 hours off has proved to be a great combination over a wide range of species. Of course, if you have a bright window near your terrarium, that will suffice, but direct sunlight for more than a few minutes per day should be avoided. Disregard outdated advice in old books which is constantly repeated on the internet to colonize mushroom substrates in total darkness. Experience and rigorous peer reviewed studies have proved that exposure to low level ambient indoor lighting during spawn run and substrate colonizing will speed up the process, leading to full colonization up to a few days earlier than the same substrate would if colonized in darkness. In addition, mushroom mycelium develops a day/night circadian rhythm, so exposure to light from day of inoculation sets this process in motion, leading to earlier fruiting and harvest.""

I don't agree with the campaign against bulk growing... but Cue is a good grower who has shared many crops across many sites. Just saying.

Most of Anne's close associates grow bulk manure... I noticed. Which I find interesting.
They promote fert-grain, but then grow Amish-style 'turd tubs, like the rest of us.
