Another approach to growing cucumbers indoors

I have two Little Leaf cucumber plants growing in AutoPots under a red/blue/white 90 watt LED, and they seem to be doing fine up to this point.

As I had four seedlings left over, I thought I would try to grow them under a red/blue LED in what I refer to as my modified aeroponic unit.

My intention is to compare the difference in growth, if any, between a passive system, such as the AutoPots, and an active system, such as the modified aeroponic system.

Additionally, I wanted to try some of the additives that I received as samples, so I concocted a witch's brew containing: Peter's Professional, calcium nitrate, epsom salts, Athena's Aminas, Olympus Up and Zeus Juice in various proportions. The TDS is a comfortable 1610 and I adjusted the pH to 5.5.

As usual, I will be running a 14 hour photoperiod, and the nutrient cycle is going to be one hour on and three hours off.

As stated above, my objective is to compare the growth rate between the two systems and evaluate the supplements, so I may just continue this grow until I have achieved those objectives. I am also curious to see if the plants flower with only the red/blue spectra.
