Our biggest lettuce plants are now 9" in diameter. You can't keep them down! As you can see, though, we've added some plastic mulching around them. You can no longer see the media, but trust me, it's there. This is to help prevent any algae growth down the road. We want to make sure all nutrients and oxygen are going straight to our green leaf lettuce!
We're also excited that the much younger seeds in our raft system are taking root (literally). Their roots are now through the rock-wool into the nutrient-rich water. Hopefully they start shooting up soon! The bigger sprouts are our lettuce and the smaller ones are our rosemary - apparently it's a slow-grower in comparison. We can't wait until we can sample some of our product!
