Just a quick update for anyone interested in the progress of my DIY LED growlight experiment.
The system has been unmodified since last week. Below is a photo of the lettuce experiment after 3 weeks.
I’m still quite impressed with the progress of the lettuce growth. I’ve thinned out quite a few of the lettuce and had 2 salad which they made a nice addition to. Some of the lettuce are doing really well, but one side is definitely doing better than the other. I’m sure this is due to uneven light distribution, which I’ll try and sort out over the next week or two when I update the growbox system.
Also, I wonder if hey need feeding soon as there’s not that much compost in the container.
