Caulis in containers

floyd

I have bought some cauli Avalanche F1 seeds that are apparently a good option for container growing. What I am unsure of is how to plant them as the instructions say to sow in a seed tray at a minimum of 15c until germination or thinly in a seedbed 1/2 inch deep and then to transplant 5 weeks later.

If I intend to grow them in 18 inch diameter pots can I just sow directly into the final pots or will it be too cold for germination to occur?

Thanks in advance

I would grow them in seed trays first, then when big enough plant them in your pots.
