Christmas light LED grow box – Update #1


I have been pretty impressed with the results of the Christmas lights LED grow box so far. I did have some preconceptions that I may need to double the lights or upgrade the LEDs, but so far the plants look healthy without white leggy stems, though still need to wait until the true leaves come in. As you can see in the picture above I have quite a selection of pots reused from previous years. The one exception are the newspaper pots which I discovered last year and am definitely a fan of.  You can also see from the gross white stuff that my grow box probably could use a fan or at least prop a corner open.

Here is a picture of one of the cucumber plants up close.


My experiment is being conducted in the LED grow box so for its update, looks like is in the lead but hard to say with just germination occurring.

    I’m a big fan of newspaper pots too. I only use them for things that are harder to transplant (like cucurbits) but they work very well.

    Hi there, LED grow box? Are you speaking of using LED lighting and nothing else special (besides the cool newsprint pots of course) I would love to do some indoor gardening and you have inspired me.

    I was researching this 3 years ago from a college that did this and they had stunning results. They used 80% red and 20% blue. The plants grew to a certain height next to the outdoor plants to a certain height and stopped. Was impressed enough to try it my self with the soldiering method. Blew up my leds. Need more research and added current resistors around a 12 volt supply in parallel. Anyway I was thinking of using the disc’s from cheap led flashlights next . They make them in several colors and are shipped free from hong kong. Take out the disc and wire them up. They have them up past 109 led flashlights that I have purchased over 2 years ago. Time to put them to use. Just take out the disk and throw the rest away. A couple of sites I use are and the other is They also have led’s on a roll to for over a year just now making it’s way to the u.s. market.

    You mentioned the problem of air circulation. Perhaps you could rig up two computer case fans to pull fresh air through the box?

    This is a fascinating case-study. I know that people use LEDs to grow plants, but I never would have thought to try it using Christmas lights in a shoebox. Great stuff my friend. haha
