Because this project is modular you can make it as big as you need it.

I made my light with four modules, to make the same size as me you are going to need:
“the reason why you don’t think this is enough light is because unlike nasa you are using regular LEDs. you need to use at least 1W high power LEDs.”

If all the LEDs doesn’t light up go back and check your wiring and soldering.
Parts

  1. 40 red LEDs
  2. 16 blue LEDs
  3. 20 56 ohm resistors
  4. 16 100 ohm resistors
  5. 2 blank circuit boards – 5 x 7 cm
  6. USB cable
  7. USB charger
    1. Any power source with 5 V and more than 720 mA will do
  8. Hookup wires

However if you reconfigured the LEDs into a 1″ by 9″ light bar some of the light will travel straight down to the top leaves while some light will travel at a steep angle, miss the top leaves, and then hit the lower leaves. Larger light sources have less distinct shadows and better light penetration.

If you browse online you’ll discover that conventional seed starting lights are quite expensive. Luckily, I have great news — you don’t need one of those fancy light racks. You can easily assemble your own seed starting rack with materials from your local hardware and big box store.

The Lights
There are lots of LED and high performance grow lights out there, but you don’t have to get anything fancy if you don’t want to. For many years I’ve been using standard 48″ long shop lights that hold two fluorescent bulbs.
Additional Materials For Your Grow Lights
Timer: Your lights should be on for 12 hours per day and off at night. The easiest way to ensure this happens is to plug everything into a digital timer.

If you’d like, you can watch the video above where I show you the simple list of parts that make up my home grow light stand and then you can read the post below to find links to all of the supplies I talk about in the video.
If you prefer to shop on Amazon, find all of the supplies here.
Although you’ll need some extra cash to get started, most of these things are a one-time investment. You can use them over and over again every year.
Due to the heat the fixtures produce the soil dries out very quickly and the seedlings under this light need to be watered more regularly than the seedlings on the other shelves. Neither of these things happens with regular fluorescent or LED bulbs.
I position the grow light in one of the middle two bulbs on the shelf so its light is more likely to reach all of the seedlings.

Another option for a light is this fixture, which I purchased a few years ago in order to compare it to the standard shop lights. After using it for several years I don’t necessarily prefer it over them.

It's very difficult to grow healthy seedlings in front of a window. Instead, assemble your own DIY grow light stand with supplies from the hardware store.
