LED Experiment Week 4 Update.

Week One

one-week

As noted earlier the plant under the 9 grow emitters seemed to suffer from transplant shock, the others are all doing well.

Week Two

At two weeks into the experiment the plant under the 9 “grow” emitters is still stunted compared to the others but it is recovering. At this point I am fairly comfortable blaming transplant shock rather than the emitters for it’s appearance. To support this the plant under the 6 “grow” and 3 Red emitters appears to be one of the more vigorous plants. Also at two weeks it appears that the plant under the 9 Cool-White emitters is lagging in growth and finally the plant under the 6 Red:3 Blue emitters is starting to show a greater depth of colour than the other five plants.

Week Four

s28days

After four weeks the plants have become large enough that I don’t want to remove the partition in fear of damaging them when I replace it. Unfortunately this makes for a rather poor photo. For the update on week six I think I will remove the plants and photograph them individually.

I don’t want to make any significant observations at this point, not least because the photograph from the top down angle isn’t the best. That being said the photo does show that the stunted plant has recovered but is obviously still lagging in growth, and the plant under the 6:3 Red:Blue light continues to show a greater depth of colour than its peers.
