Growing in MFBs (flower buckets from shops)

Hi all,

Now that we have a Morr*sons near us, I have been spying some of the MFBs on offer (8 for 99p, I think). They look about 35 cm or 14 inches high, something like that. I imagined them a bit bigger, for some reason. I usually need more pots for chillies, peppers, tomatoes, melons, in the GH, but I'm not sure what is a good fit for this size pot.

In any case, I'm wondering what you grow in this size pot.

Please fill my head with ideas for GH growing!

Thanks
