How do you get good caulifowers?

[Tee Gee]

They are growing well nice and healthy when will I get heads on them?

This is difficult to say as it can depend largely on the variety.

Having said that I find when the leaves start to curl inwards this is the first sign of curds forming (see picture)

At the moment I only grow fruit (no time or space for more).
Does it make economical sense to grow cauliflowers with the time you send on them?

L/D  do you grow cabbage or sprouts?   If so you can grow cauliflowers.
Well dug bed.   Plant deep.  Puddle in.  Slug pellets.  Net.  Keep watered if necessary.  Weed carefully so not to disturb.  Await crop.

You make it sound soooooo simple!  :)
