The tomato/capsicum/chilli seedlings were taking over the house so I decided it was time for them to move out.
The balcony is ideal for this purpose. Line the trellis with leftover polycarbonate sheeting, put another sheet on the floor (to protect it from all the water) and move the plant stand over to hold all the boxes. Cover the boxes with a plastic sheet overnight and during cooler days. Take it off on warm, sunny days. So far they seem to be happy in their new home.
