If you don't have a sunny, south facing window, you can use a single light bulb or invest in florescent, high density plant light, grow lights and/or a timer.  It's
As above it depends what seedlings you have but I would be wrapping something around your shelf (plastic sheet, blanket, mylar, tinfoil)to keep the heat in and put an incandescent light bulb

I think the secret is to have lots of organics in the mix. The other critical part is mulch! I

After a bit of researching, my own light bulb came on and I realized that besides fibrous vegetables, nuts and seeds are possibly the best focus, as they can offer a good bit of protein and low
Bees wax versus tallow. Candle versus oil lamps.  Whale oil versus petroleum oil.  Oil versus gas.  Gas versus arc lights.  Arc versus incandescent.  Incandescent versus halogen versus xenon versus
control projects. All our light bulbs are LED so they use a very small amount of power. One of our showers is heated by black pipes with the sun's rays. All of our grey waste water goes into a banana
As far as color quality goes, there is an actual system for describing it for non-incandescent light bulbs. It's called "Color Rendering Index" or CRI. Incandescents by default have a CRI of 100
Looking for suggestions for a decent grow light for seed starting indoors?  I am currently using 24" florescent bulbs and get decent results.  I am not sure if there would be a benefit to the LED's

Hello Kevin,

Prickly pear doesn't cast a great deal of shade and for this reason I like to pair it with groundcovers that will intercept the remaining light. Here's a list of different plants I've

in a suburban neighborhood, the creepiest thing is the random hovering light of a doorbell on an unlit porch. They're just the color of a flame, but aren't flickering and they're not round like most bulbs

Use heated lighting for your sitting areas during winter. They cost as much to run as a heated blanket, but give the feel of a nice summer's day
??  Sorry forgot to say we have all electric and we do have led bulbs in light fixtures and most cooking is done on stove top..not oven!  Thanks!!

The advice about questioning the bill

the solution may be on its way

words, artificial light.  Most light bulbs these days are mercury based, that is to say

already mention the bulb's voltage rating esp. with regards to long-life bulbs.  IIRC they mostly just make the wire filament thicker, which makes it less efficient in lumens / watt, but does make it last
an incandescent light bulb will make a fair amount of heat..
It's going to get hot in the sunshine too, and quickly so you'll need to be around to open it up a bit to regulate the temperature.
Rendering Index

High-CRI bulbs put out a much better spectrum than others and are prized in Photography, Supermarkets, and Jewelry stores (who were really quite stuck on Halogens for the longest time

I hope that the stuff I'm trying this year doesn't do that. 

I also stocked up on incandescent light bulbs and am toying with the idea of hanging

It is a complete LAMP.
But if you have a light bulb, the same electronics + LED's must be crammed in a smaller space -> a lot higher temperatures.

We are at the end of the world literally. We are the true end of a feed off the power grid. When we
bulbs have more than one element, LEDs could have a wider spectrum of light... I don't think the cost would be much more, if any. (higher design costs maybe)
I think that LEDs used in low voltage

I too love Edison bulbs for their look, and candles. However to deal with my SADD, I need the brighter lights. Something that returns 95% of the energy put
), but it may be that I don't have total control over my lighting at the moment as I share accommodations and the house came with various light bulbs already.

That all said, I am hoping to build
fine, however you also need to take into account what else changes as you vary the voltage. Lower voltages will produce warmer light; your 6500K bulb is not producing that color mix light when you run
Haven't read the whole thing but I appreciate your doing the math, Paul.

. It's interesting that they make the bulb not so much for health reasons but rather for better rendition of colours in store displays and so on.

my head for the light bulbs! It would have been nice to have another foot of headroom, but if I had done that, I would have had a really low pitched roof. It worked out, but barely!

I'm on episode three of the first season with the duck guy.
I already learned that I want a screw in ceramic heater vs the light bulb I've always used in my brooder! 
Thanks for the suggestion
of incandescent light bulbs. Ernie explains how Paul is wrong. They talk about how the power companies are uninterested in you actually reducing your consumption. Ernie underlines that your heat bill is one
of the volume of the pot and small nature of the tree the damn thing takes awhile to dry. I wonder if that's causing nutrient deficiency? Who knows I'll try the light that had a light bulb go off for me.
obviously changes daily. I just leave the light switch turned on, but it is only one cfl bulb so it is not a huge cost. The grain room light adjacent to th coop has a second light hat we only use when we
