Then fill with soil or potting mix and plant out your seedlings. We have tomatoes and cauliflower in at the moment. I am just using a single stake in the centre of the tub, for all of the tomato plants. We will see how this goes.
The tubs get hardly any weeds, are higher up for ease of planting, they are light enough to move around the garden easily and could even be put up on a bench, for no-bending gardening. Perfect for balconies, and renters (like us).
