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.
