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.

No one who has actually done any testing with lighting during pinning and fruiting

I never said there was. I merely said people have preference.
