Photo Update: Time-Lapse test shot (LED Lettuce)

Today the long-awaited red/blue LED experiment has gotten underway. That is, the plants have been moved into their new reservoir below the LED panels. I spent some time today setting up the time-lapse camera and getting the focus/etc corrected. Below is a test shot from that camera, indicating approximately how the time-lapse videos will look. It's a little strange that this setup is totally in the dark, but I want to exclude all secondary sources of light.

Some details you might find interesting:
-The camera is set up to take photos every fifteen minutes during the 'daylight' hours of the experiment.
-The lettuce is receiving 13 hours of light per day, so we'll get about 52 shots per day.
-The lettuce is being fed Maxi-Grow dry nutrient from General Hydroponics, at a concentration of 1 teaspoon per gallon.
-The reservoir holds 7 gallons of solution.
-The solution pH is being kept at 6.5
-Solution temperature is 68 degrees.

You'll notice the camera is set up a bit high, or that the plants appear very low in the frame. This is to make space in the frame for the (hopefully) explosive growth we're about to witness.

  1. Looks good! You could also set up a webcam to provide constant feedback on your experiment. And if you wanted to you could set the plants up in suggestive positions and charge per the hour. It's a gold mine Bucket, a gold mine!
