Salad garden Part1

Only 7 days after sowing the first batch of lettuce, tiny shots have appeared. They are growing in a large trough which has been divided into 3 sections. Each section will grow the same lettuce varieties with 2 weeks intervals. Thus providing a longer abundance of salad leaves. The next sowing will be done on 3rd and 17th June.

Now all Ive got to do is keep the slugs away. Im sprinkling slug pellets once the last lot have dissolved. Im slightly worried that I may be creating a pollutant in the soil. The Hostas in their second year seem to have escaped slug damage, whether that is because they are not so tasty or the slugs were not around when the Hostas started to grow, im not sure.
